Abstract
The cichlid genus Archocentrus has been considered one of the most promising (i.e., possibly natural) genera resurrected
to receive some of the species formerly included in Cichlasoma. Evidence is presented to justify generic recognition of
Archocentrus, as well as eight other closely related genera (Caquetaia, Hypsophrys, Parachromis, Amphilophus, Archocentrus, Cryptoheros, Amatitlania, and Rocio). Of these, Amatitlania (type species, A. nigrofasciata) and Rocio (type
species, R. octofasciata) are described as new. The present revision treats all nominal species ever assigned to Archocentrus, as well as species that have been included in or near the same clade as Archocentrus centrarchus (type species of the
genus) in available phylogenetic analyses. Geographical variation in morphology of the more widespread species was
examined, which has resulted in the description of six new species (Cryptoheros chetumalensis, Amatitlania coatepeque,
A. kanna, A. siquia, Rocio gemmata, and R. ocotal) with a seventh resurrected from synonymy (Cryptoheros cutteri).
Archocentrus includes the type species (Ar. centrarchus), plus Ar. spinosissimus and Ar. multispinosus. Cryptoheros is
restricted to the species complexes of Cr. spilurus (= subgenus Cryptoheros, including also Cr. chetumalensis and Cr.
cutteri) and Cr. septemfasciatus (= Bussingius n. subgen., including also Cryptoheros altoflavus, Cr. nanoluteus, Cr. myrnae, and Cr. sajica); Cryptoheros panamensis is placed in Panamius n. subgen. Herotilapia is synonymized with Archocentrus, and Neetroplus is synonymized with Hypsophrys, which now includes the type species H. nicaraguensis and H.
nematopus. Lectotypes are designated for Amatitlania nigrofasciata, Archocentrus spinosissimus, Cryptoheros septemfasciatus, Cr. spilurus, and Rocio octofasciata. Cichlasoma immaculatum is considered to be a synonym of Archocentrus
spilurus, not of Ar. spinosissimus.

Resumen
Archocentrus (Cichlidae) se ha considerado uno de los géneros más prometedores (es decir, posiblemente natural) resucitado para recibir algunas de las especies antes asignadas a Cichlasoma. Se presenta evidencia que justifica el reconocimiento a nivel de género de Archocentrus, así como otros ocho géneros cercanamente relacionados (Caquetaia,
Hypsophrys, Parachromis, Amphilophus, Archocentrus, Cryptoheros, Amatitlania y Rocio). De éstos, Amatitlania (especie tipo, A. nigrofasciata) y Rocio (especie tipo, R. octofasciata) se describen como nuevos. La presente revisión trata
con todas las especies nominales alguna vez asignadas al género, así como las especies que han sido incluidas dentro o
cerca del mismo clado que Archocentrus centrarchus (especie tipo del género) en los análisis filogenéticos disponibles.
Se examinó la variación geográfica en morfología de las especies de distribución más amplia, lo cual resultó en la
descripción de seis especies nuevas (Cryptoheros chetumalensis, Amatitlania coatepeque, A. kanna, A. siquia, Rocio
gemmata y R. ocotal) y una séptima rescatada de la sinonimia (Cryptoheros cutteri). Archocentrus incluye a la especie
tipo (Ar. centrarchus), junto con Ar. spinosissimus y Ar. multispinosus. Cryptoheros se restringe a los complejos de Cr.
spilurus (= subgénero Cryptoheros, incluyendo también a Cr. chetumalensis y Cr. cutteri) y de Cr. septemfasciatus (=
Bussingius n. subgen., incluyendo también a Cr. altoflavus, Cr. nanoluteus, Cr. myrnae y Cr. sajica); Cr. panamensis se
coloca en Panamius n. subgen. Herotilapia se sinonimiza con Archocentrus, y Neetroplus se sinonimiza con Hypsophrys,
el cual ahora incluye a la especie tipo H. nicaraguensis y a H. nematopus. Se designan lectotipos para Amatitlania nigrofasciata, Archocentrus spinosissimus, Cryptoheros septemfasciatus, Cr. spilurus y Rocio octofasciata. Cichlasoma
immaculatum se considera sinónimo de Ar. spilurus, no de Ar. spinosissimus.
The arrangement of the American cichlids into genera is a puzzle of great difficulty.

Introduction
The cichlid fish genus Archocentrus was originally proposed as a subgenus of Heros Heckel by Gill (in Gill &
Bransford 1877), and later treated as an informal “section” of Cichlasoma Swainson in Regan’s (1905) revision of the genus. The generic status of Cichlasoma sensu Regan (1905), encompassing more than 100 species, has been in a state of uncertainty since Kullander’s (1983) restriction of Cichlasoma sensu stricto to 12
South American species. Of the many remaining groups of species formerly referred to Cichlasoma, those

referred to Archocentrus have been among the strongest candidates for recognition as a monophyletic group
(e.g. Miller 1993, Miller et al. 2005). Species assigned to Archocentrus are major components of the neotropical Central American ichthyofauna from southern Mexico to Panama, occurring across all the ichthyolimnological provinces of Bussing (1976), but the monophyly of the genus has not been explicitly demonstrated and
its species composition has been far from clear.
Since a comprehensive analysis of Cichlasoma sensu lato appeared unlikely, Kullander (1996) advocated
the provisional use of available generic names, a procedure that some workers had already adopted. Kullander
himself (1983), Stiassny (1991), and Miller (1993) had earlier recommended that the use of ‘Cichlasoma’—
with the quotation marks indicating its informality— would prevent further confusion. Because the systematics of all species previously referred to Cichlasoma had not yet been completely resolved, Nelson et al. (2004:
151–153) chose the conservative approach and tentatively referred all species to Cichlasoma in the most
recent checklist of fishes for the United States, Canada, and Mexico.
Several species have been assigned to Archocentrus more or less consistently in the literature (Table 1).
Allgayer (2001) restricted Archocentrus to include the two largest species (Ar. centrarchus and Ar. spinosissimus), and referred six others to a new genus, Cryptoheros (type species, Cr. spilurus), which also included the
new species Cr. altoflavus. Other species that have sometimes been assigned to Archocentrus (Table 1)
include: Heros octofasciatus, though more frequently placed in incertae sedis; H. citrinellus, albeit demonstrated by Roe et al. (1997) to be an Amphilophus; H. multispinosus, generally considered in the monotypic
genus Herotilapia; and Neetroplus panamensis, variously included in Archocentrus (in Kullander 2003),
Theraps (in Eschmeyer 2001), or Hypsophrys (in Bussing 1998).

To complicate things further, variation within some Archocentrus species has not been evaluated before.
Hubbs (1936) observed tantalizing meristic and morphometric differences among populations of Cichlasoma
octofasciatum, but he chose not to describe any subspecies because, in his material, geographic differences
were confounded with differences in body size.
Considering the potential for undetected biodiversity within presently recognized species, especially those
more widely distributed, lectotypes are designated in the present work: Amatitlania nigrofasciata, Archocentrus spinosissimus, Cryptoheros septemfasciatus, Cr. spilurus, and Rocio octofasciata. Cichlasoma immaculatum is shown to be a synonym of Cryptoheros spilurus and not of Archocentrus spinosissimus, although it was
first described as a “variety” of the latter.
The present revision treats all nominal species ever assigned to the genus Archocentrus, as well as species
that have appeared in the same clade as (or as sister group to) Archocentrus centrarchus in relevant phylogenetic analyses (Roe et al. 1997, Martin & Bermingham 1998, Farias et al. 2000). Six new species are
described and a seventh is resurrected from synonymy. Archocentrus, Cryptoheros, and Hypsophrys are redefined, and two new genera (Amatitlania and Rocio) are diagnosed.
Genus–level decisions in this work are supported by a phylogeny (Schmitter-Soto, in press), published
separately, which includes most character illustrations and analysis.
Material and methods
The specimens studied include representatives of all nominal species that have at various times been assigned
to the genus Archocentrus (Table 1), as well as comparative material of species that appeared in the same
clade(s) as species assigned to Archocentrus in Roe et al. (1997), Martin & Bermingham (1998), and Farias et
al. (2000) (Table 2). Material of the more widely ranging species was selected in order to include the species’
entire geographic range (see Material examined in Appendix 1).

Pigmentation patterns were assessed primarily from preserved specimens. Osteological methodology (i.e.,
clearing and staining) follows Taylor and van Dyke (1985), as modified by W.L. Fink (pers. comm.). Radiographs and skeletonized specimens were also used. Bone measurements were taken with an ocular micrometer. Some body measurements (e.g. interorbital width) were taken with vernier calipers, but most were taken
from digital photographs using tpsDig (Rohlf 1999). Measurements and counts are standard (Hubbs & Lagler
1958), except that lateral-line scale-count methodology requires discussion. The lateral line in cichlids is separated into two disconnected segments, which overlap on the posterior part of the body (see Nelson 1994:
6 · Zootaxa 1603 © 2007 Magnolia Press
SCHMITTER-SOTO
381). The procedure used here was to count those scales only in the upper of the two overlapping segments,
then include the remaining scales in the lower segment posterior to the zone of overlap in order to obtain a
total count. The last dorsal and anal fin rays were counted as one only when joined at the base, a condition
usually checked in cleared and stained specimens. The number of scales between the vent and the origin of the
pelvic fin does not include the interpelvic scale. The interpelvic scale is an enlarged scale (sometimes a group
of 2–3 scales) between the bases of the innermost pelvic-fin rays, overlapping the rays; the scales included in
the count do not overlap any ray. Anal creases refer to the intestinal folds, as counted on the anus, viewed
from the outside.
Gut-coiling patterns were illustrated from the right side of the fish, in order to keep stomach and liver,
which are on the left side, out of view. Most widespread within the studied species is the pattern here termed
“simple,” or “S-shaped,” which is retained from juveniles to adults in most cichlids: the gut depicts an S,
forming first (from the vent to the mouth) an “anal loop” rostrally, then turning caudad to form a “medial
loop,” then again rostrad to a “rostral esophageal loop,” then once again caudad to a “caudal esophageal
loop,” and finally to the esophagus, which it joins at approximately the same point as the stomach. The rostral
esophageal loop and the caudal esophageal loop are less abruptly folded than the anal and median loops,
which are rather evenly rounded. The basic simple pattern shows variations of taxonomic interest. The Intersecting Point (IP) is a complexity index defined by Yamaoka (1982) as the number of intersections of the gut
with an imaginary left–right line (here modified as a dorsoventral line).
Results
The identification key provided here includes all species in the genera Archocentrus, Cryptoheros, Amatitlania, Rocio, and Hypsophrys, all of which include species once assigned to Archocentrus. The key has been
modified from various sources (Villa 1982; Greenfield & Thomerson 1997; Bussing 1998; Schmitter-Soto
1998; Miller et al. 2005). The genera Amphilophus, Caquetaia, and Parachromis, which showed up within the
ingroup in the phylogenetic hypothesis of Schmitter-Soto (in press) are included for comparison. Abbreviations: SL, standard length; D., dorsal fin; A., anal fin; Roman numerals after D. or A. indicate spines; Arabic

29; predorsal scales 12–17; scales from vent to interpelvic scale 6–9; circumpeduncular scales 15–21; anal
creases 10–15. Species small, less than 110 mm SL. Body rather oval, deep, depth 47–61% of SL. Head length
10 · Zootaxa 1603 © 2007 Magnolia Press
SCHMITTER-SOTO
33–35% of SL. Snout short, length about 25% of head length. Orbital diameter 24–33% of head length. Caudal peduncle twice as deep as long; least depth 16–19% of SL. Head profile straight or concave to above
orbits, convex at nape. Lips not medially narrow; pectoral and pelvic fins long, always reaching posteriorly to,
or beyond, 3rd anal-fin spine. Origin of pelvic fin posterior to a vertical from origin of dorsal fin. Gut equal or
longer than body. Seven vertical bars on side of body; dorsal and anal fins immaculate or with dots in a checkered or diagonally-aligned pattern. A blotch on scaly base of caudal fin, which crosses lateral line, ocellated or
not.
Distribution. Pacific slope of Central America from Costa Rica (Río Tempisque) to Nicaragua (Río Guasaule); Atlantic slope from Costa Rica (Río Matina) through the Great Lakes of Nicaragua to Guatemala (tributaries of Lago Izabal) (Fig. 1).
FIGURE 1. Distribution of the species in the genus Archocentrus. Squares, Ar. centrarchus; circles, Ar. multispinosus;
triangles, Ar. spinosissimus. A symbol may represent more than one collecting site.
Species composition. Archocentrus as restricted here includes only three species: Ar. centrarchus, Ar.
multispinosus, and Ar. spinosissimus.
Remarks. The synonymization of Herotilapia is discussed and justified below.

Holotype. USNM 16878, J. F. Bransford, Mar. 1, 1876. Lake Nicaragua, Nicaragua. No paratypes (see
Remarks).
Diagnosis. Autapomorphies (Schmitter-Soto, in press): total gill rakers on first arch 16–19; gill rakers
elongate, slender; two opercular spots, vertically aligned. Further diagnosed from other species of Archocentrus by absence of a concavity at posterior end of maxilla; circumpeduncular scales modally 18 or fewer (vs.
19 or more); presence (vs. absence) of rows of secondary pored scales on caudal fin; bars on side of body
extending partially onto dorsal and anal fins (vs. bars confined to sides of body), absence (vs. presence) of
medial intensification in bars on side of body, presence (vs. absence) of ocellus on dorsal fin of mature
females; abdomen predominantly yellow-green in life (vs. abdomen predominantly bluish, whitish, yellow or
black); and caudal blotch ocellated (vs. not ocellated).
Description. D. XV–XVII,7–9; A. IX–XI,7–9. Gill rakers on lower limb of first arch 12–17; gill rakers
long, especially on ventral side, and serrated. Scale rows on cheek 4–6; pored lateral-line scales (not counting
scales overlapping between the two segments of the lateral line) 25–29; scales from lateral line to base of first
dorsal-fin ray 1.5–3; circumpeduncular scales 15–17. Additional meristic data appear in Table 3.
Largest examined specimen 102 mm SL. Body rather oval, deep (50–57% of SL), horizontally almost
symmetrical in profile. Head profile straight or concave above orbits, convex at nape. Head length 33–34% of
SL; orbital diameter 24–27% of head length (further morphometric data appear in Table 4). Maxilla extending
to ventral rim of orbit; premaxilla extending to anterior rim of orbit. Teeth embedded, conical, slightly retrorse, upper symphysial teeth not abruptly larger, lower symphysial teeth subequal to adjacent teeth. Lower
jaw slightly protruding. Lower lip at corner of mouth not tapering, rounded or squarish. Frenum of lower lip
usually absent (not “present”, contra to the original description).
Pectoral fins reaching posteriorly to 5th–6th anal-fin spine; pelvic fins reaching to 6th–9th anal-fin spine; distal pelvic ray not bearing filaments. Filamentous rays of dorsal fin extending to about middle of caudal fin.
Caudal fin definitely truncate to slightly emarginate. Scales weakly ctenoid. Subsidiary pored scales on caudal
fin forming 3-scale–long rows; scales between anal fin rays in one or two rows, 6–11 scales long.
Gut simple, about as long as body; intestinal anal and esophageal loops adjacent. Genital papilla tongueshaped, in adults deeply notched or strongly crenulate; longer than wide in females, may be wider than long in
males; pigmented on tip, but with little pigment on posterior side.
A vertical bar on head; two interorbital bands; a suborbital streak; diffuse stripe from snout to eye; no
speckles on cheek; two spots characteristically on opercle. Eyes golden, yellow or reddish. Seven vertical bars
on sides; 1st bar curved on head, all bars well marked medially and dorsally, 4th and 6th bars extending onto
dorsal fin, no lateral spot discernible on bars. Blotch on dorsal fin over 6th bar sometimes ocellated; soft dorsal
fin occasionally with two rows of dots forming a checkered pattern, but elsewhere unpaired fins mostly
immaculate,. Rows of spots on sides 11–14, smaller than scales; breast region golden in juveniles, bronzegreen in adults. Axil of pectoral fin and base of pectoral fin with same coloration as breast. A black caudal
blotch, on fin, across lateral line (not “chiefly above,” contra the original description), ocellated.

Remarks. Although the specimen BMNH 1905.3.27.2 (Fig. 2) is labeled “cotype”, Gill and Bransford
(1877: 186) left no doubt that they had only one specimen (i.e., the holotype) at hand. The BMNH specimen
therefore has no formal type status.

Holotype. BMNH 1865.7.20.34, 68 mm SL (Fig. 3) , J. M. Dow. Lake Managua, Nicaragua. No paratypes.
Diagnosis. Autapomorphies (Schmitter-Soto, in press): both upper and lower symphysial teeth tricuspid;
basally two rows of interradial scales on anal fin; rostral arm of articular bone only a little longer than dorsal
process (ratio ca. 0.87, vs. 0.77 or less in other Archocentrus); gut with IP = 6. Also diagnosable from all other
Archocentrus by a sigmoid (vs. irregular) posterior edge of urohyal; coronal pore triple (vs. single); narrowest
point of dentigerous arm of premaxilla at caudal tip (vs. before tip). Truncate caudal-fin profile, synapomorphic with A. centrarchus (vs. rounded-truncate in A. spinosissimus).
Description. D. XVIII–XIX,8–9; A. XI–XII,7–8; gill rakers on lower limb of first arch 8–9; gill rakers
blunt, their ends trapezoidal, serrated. Scale rows on cheek 4–5 (contra Stawikowski & Werner 1998, who
counted 3); pored lateral-line scales (not counting scales overlapping between the two segments of the lateral
line) 27–29; 2.5 scales from lateral line to base of first dorsal-fin ray; circumpeduncular scales 19–21 (further
meristic data appear in Table 3).
Largest examined specimen 87 mm SL. Body rather oval, usually not so deep (47–54% of SL) and not so
symmetrical horizontally, the curve of the nape somewhat more pronounced than the curve of the thoracic
region. Head profile straight above orbits, convex at nape. Head length 33–35% of SL; orbital diameter 26–
28 · Zootaxa 1603 © 2007 Magnolia Press
SCHMITTER-SOTO
33% of head length (other morphometric data appear in Table 4). Maxilla extending to ventral rim of orbit;
premaxillary dorsal process not reaching anterior rim of orbit. Teeth not embedded; incisors tricuspid (Pellegrin 1904: fig. 20, 4), symphysial teeth aligned with adjacent teeth. Lower jaw not protruding. Lower lip at
corner of mouth square, not rounded, the angle varying from right-angled to acute. Frenum present on lower
lip.
FIGURE 3. Archocentrus multispinosus, holotype, BMNH 1865.7.20.34. Photo, BMNH, London.
Pectoral fins reaching posteriorly to 3rd–5th anal-fin spine, and pelvic fins extending to 4th–6th anal-fin
spine; distal pelvic ray may bear filaments. Filamentous rays of dorsal and anal fins extending to about proximal third of caudal fin. Caudal fin truncate (contra Günther 1869 and Pellegrin 1904, who considered it
rounded). Scales strongly ctenoid. A few, sporadic subsidiary pored scales on caudal fin, not forming rows;
scales between dorsal fin rays, proximally in two rows, the rows up to 14 scales long.
Gut strongly coiled, IP = 6. Genital papilla longer than wide (may be wider than long in females), widest
at base, deeply notched, sunken; no pigmentation, except for base and sides.
A vertical bar on head; two interorbital bands; no suborbital streak; diffuse stripe from snout to eye; no
speckles on cheek; a spot on opercle, which represents an anterior expansion of longitudinal stripe on side of
body. Eyes orange. Seven sharp vertical bars on sides, broader than interspaces, and usually double; 1st bar diffusely Y-shaped; a longitudinal stripe from orbit to a circular, jet-black blotch on 4th bar; bars on side of body
not extending onto dorsal fin. No ocellus on dorsal fin; dorsal and anal fins immaculate or with 3–4 rows of
dots. About 12 rows of spots on sides, smaller than scales; breast region olive-yellowish. Axil of pectoral fin
with same coloration as breast or dusky; base of pectoral fin with same coloration as breast or slightly paler. A
black caudal blotch, on fin, across lateral line, the blotch not ocellated.
Distribution. Atlantic slope, from Costa Rica (Río Matina) through the Great Lakes of Nicaragua to Honduras (Río Patuca); Pacific slope, from Costa Rica (Río Tempisque) to Nicaragua (Río Guasaule) (Fig. 1).
Panamanian records (e.g. BMNH 1925.3.6.165) are based on misidentifications.
Remarks. Pellegrin (1904) put the species in a monotypic genus because of the “dentition tout à fait caractéristique” (surprisingly not observed by Günther 1867 or 1869); on the other hand, he considered it
“[v]oisin de Neetroplus.”

A. multispinosus exhibits striking and abundant autapomorphies, but its relationships to the other two
Archocentrus are not resolved (Schmitter-Soto, in press). Considering this, it seems best to apply only one
name to the monophyletic group formed by the three species.

Paralectotypes. MNHN 2005-0780 (3; 58, 59, and 74 mm SL).
Diagnosis. Autapomorphies (Schmitter-Soto, in press): vertical bar on head, extending just across nape,
not present on opercle; distally three rows of anal interradial scales. In addition, caudal fin rounded-truncate
(vs. definitely truncate) in the other species of Archocentrus.
Description. D. XVII–XIX,7–10; A. XI–XIII,7–9; gill rakers on lower limb of first arch 6–8; gill rakers
bifid or at least distally expanded, trapezoidal, serrated. Scale rows on cheek 4–6; pored lateral-line scales (not
counting scales overlapping between the two segments of the lateral line) 26–28; scales from lateral line to
base of first dorsal-fin ray 3.5–4.5; circumpeduncular scales 19–21 (additional meristic data appear in Table

nape. Head length 34–35% of SL, head deeper than long; orbital diameter 28–29% of head length (further
morphometric data appear in Table 4). Maxilla not reaching a vertical line from anteriormost rim of orbit, but
extending to a horizontal line from inferiormost rim of orbit; premaxilla reaching anterior rim of orbit. Teeth
embedded, canine, pointed, cylindrical, rather long, slightly retrorse; symphysial teeth subequal to adjacent
teeth. Lower jaw slightly protruding. Lower lip tapering, the ventral corner acute. Frenum present on lower
lip.
Pectoral fins reaching posteriorly to 4th–8th anal-fin spine; pelvic fins reaching to 5th–10th anal-fin spine.
Filamentous rays of dorsal fin extending posteriorly to distal fourth of caudal fin. Caudal fin rounded-truncate. Scales strongly ctenoid. Pored scales on caudal fin vestigial or absent; scales between dorsal and anal fin
rays distally in two or three rows, up to 8 scales long.
Gut simple, anal and esophageal loops not adjacent. Genital papilla rounded or vase-shaped, wider than
long; large feminine pore, tip crenulated to deeply notched; pigmented on margins (males) or just around
opening (females).
A bar extending across nape from preopercle to preopercle; two interorbital bands; suborbital streak usually pointed, slightly concave dorsally; no stripe from snout to eye; speckles on cheek aligned from chin to
angle of preopercle and along anteroventral edge of opercle; only one opercular spot, which is part of a longitudinal stripe running from orbit to lateral blotch. Eyes coppery, bluish. Seven vertical bars on sides, rather
diffuse; 1st bar diffusely Y-shaped; 1st to 5th sometimes double, none extending onto dorsal fin; a squarish or
rounded spot on 3rd bar. No ocellus on dorsal; dots on soft dorsal and anal fins in 4–6 rows, concentric on base
of third or fourth ray, a basal row all along dorsal fin. About 10–14 rows of well-marked spots on sides,
smaller than scales; breast region olive. Base of pectoral fin paler than breast, sometimes yellowish. Caudal
blotch on scaly base of fin, extending across lateral line, never forming a saddle over top of caudal peduncle,
connected to posterior speckles between rays of caudal fin.
Distribution. Ríos Polochic, Dulce, and other rivers in Lago Izabal drainage, Caribbean versant of Guatemala (Fig. 1).
Remarks. Pellegrin (1904) considered that the species “présente tout à fait l’aspect d’Herotilapia multispinosa […] elle n’est pas éloignée de C. nigrofasciatum […] et de C. centrarchus…”
Cichlasoma spinosissimum var. immaculata Pellegrin (1904), which occurs sympatrically with A. spinosissimus (and with Cryptoheros spilurus) in the Río Polochic, was considered a valid species by Regan (1905)
and Miller (1966), mainly because it lacks speckles on the fins and has up to 19 dorsal fin spines, as few as 9
anal-fin spines, and as many as 29 pored lateral-line scales. Pellegrin himself (1904) was of the opinion that,
in spite of the differences, it was not possible to categorically separate this form to species (he even called it a
“variety,” not a subspecies). Allgayer (2001) noted that it might be the female of Archocentrus spinosissimus,
the reduction or absence of speckles being a “fait aussi observé en captivité.” After examining the types, I
conclude that they are somewhat decolored (although not totally descaled, contra Allgayer 2001) specimens
of Cryptoheros spilurus. Thus, Cichlasoma immaculatum (the nomen used for this taxon by Regan [1908] and
Miller [1966]) is hereby synonymized with Cryptoheros spilurus, as discussed in the account of that species.
Genus Cryptoheros Allgayer
Cryptoheros Allgayer 2001: 14 (original description).

by a twisted median loop in adult gut (except in Cr. myrnae and Cr. sajica), and peritoneum moderately pigmented dorsolaterally (also found in Archocentrus, Petenia, and Amatitlania kanna).
Description. D. XVI–XIX,9–11; A. VII–X (VI in Cr. panamensis),7–9. Gill rakers on lower limb of first
arch 6–7, occasionally 5. Pored lateral-line scales 26–30; circumpeduncular scales 16–18, rarely 19 or 20. A
genus of small cichlids, less than 130 mm SL. Body rather oval, deep, depth 42–56% of SL. Maxilla not
reaching orbit, premaxillary dorsal process not reaching anterior rim of orbit (except in young). Frenum
present in lower lip. Filamentous rays of dorsal and anal fins extending to mid-caudal fin or beyond. Origin of
pelvic fin located behind a vertical from origin of dorsal fin. Caudal fin truncate or rounded. Scales usually
strongly ctenoid (moderately ctenoid in Cr. sajica). Up to two pored scales on caudal fin, as an extension of
the lateral line. Gut simple, with variations (secondary loops) in some species; anal and anterior esophageal
loops adjacent. Genital papilla usually tongue-shaped or rounded. No spots on cheek; vertical bar on head,
absent or faint, as a darkening of opercle and nape; interorbital bands faint or absent. Seven vertical bars on

Species composition. Nine species: Cr. spilurus, Cr. chetumalensis, Cr. cutteri, Cr. septemfasciatus, Cr.
altoflavus, Cr. myrnae, Cr. nanoluteus, Cr. sajica, and Cr. panamensis. Three clades diagnosable, here
described as subgenera, one of which is monotypic.
Remarks. The generic name was introduced by Allgayer (2001) for the “smaller Archocentrus” species,
i.e., those species included here in the subgenera Cryptoheros and Bussingius, and the genus Amatitlania, but
excluding Cr. panamensis. Allgayer (2001) also united Archocentrus, Cryptoheros, and Herotilapia in a new
subtribe, Archocentrina. However, this decision was not supported by cladistic analyses, and Allgayer did not
consider conflicting evidence, such as that presented by Roe et al. (1997) (see below).
Panamius, n. subgen.

Diagnosis. Autapomorphy (Schmitter-Soto, in press): teeth truncate and labiolingually compressed, incisor-like, but tips rounded (pointed in juveniles), their biting edges not forming a line. Further distinguished
from other species in the genus by having modally three rows of scale rows on cheek (vs. four or more); presence of single spot at posteroventral angle of opercle (vs. opercular spots absent, or single spot present but not
located at angle in other species except Cr. altoflavus); a medial intensification only of 4th lateral bar on side of
body (vs. either only on 3rd bar or none at all); dorsal edge of the articular bone straight (vs. convex); first neural spine retrorsely directed (vs. antrorse in all other Cryptoheros, except Cr. spilurus and Cr. cutteri), and two
dorsal elements between first two epineural spines (vs. three). Cr. panamensis is the only member of its genus
in which the paired fins seldom or never extend posteriorly to the first anal-fin spine, and also the only one
with six anal-fin spines (vs. seven or more) and as few as 16 dorsal-fin spines (vs. always 17 or more). Sum of
dorsal- and anal-fin spines 23 (vs. 24 or more).
Description. D. XVI–XVIII,9–10; A. VI,7–8. Gill rakers on lower limb of first arch 6–7; gill rakers trapezoidal, serrated, no basal process. Scale rows on cheek 2–4; predorsal scales 9–12; pored lateral-line scales
(not counting scales overlapping between the two segments of the lateral line) 25–29; scales between lateral
line and origin of dorsal fin 3.5–4.5; scales from lateral line to base of first dorsal-fin ray 1.5–2.5; circumpeduncular scales 14–16 (further meristic data appear in Table 3).
Maximum size 130 mm SL (Conkel 1993), although largest examined specimen during this study only 79
mm SL. Body relatively deep (45–51% of SL). Head profile convex to straight. Head length 30–34% of SL;
orbital diameter 27–32% of head length (further morphometric data appear in Table 4). Teeth not embedded;
the only incisor teeth are those near symphyses, which are rounded, its edges not forming a line; other teeth
are conical (in young, even symphysial teeth conical). Upper and lower symphysial teeth lower than adjacent
teeth in adults. Lower jaw slightly receding (contra Stawikowski & Werner 1998, who considered it terminal).
Upper lip medially narrowed; lower lip square, not rounded at corner, its lower angle acute.
Pectoral fins not extending caudad to 1st anal-fin spine; pelvic fins sometimes reaching 3rd anal-fin spine.
Filamentous rays of dorsal fin reaching posteriorly to distal third of caudal fin. Scales strongly ctenoid. Two
lateral-line pored scales on caudal fin, subsidiary pores few and sporadic; scales between dorsal and anal fin
rays in one row, up to 4 scales long.
Genital papilla tongue-shaped, rounded, longer than broad, sunken; some melanophores on basal margins.
No interorbital bands; no suborbital streak; a faint stripe from snout to eye; only one opercular spot, associated to the medial intensification of the 1st bar. Eyes greyish, reddish. No longitudinal stripe. Bars on sides
diffuse, 1st bar not divided, somewhat curved on head; 1st, 4th and posterior ones more intense medially, as
series of blotches. No bars on dorsal and anal fins, but an ocellus present on dorsal fin of mature females,
between spines X or XII to XVI or XVIII. Dots on soft dorsal and anal fins in 4–6 undulated rows, concentric
on base of third or fourth ray. About 11 rows of light spots on sides, smaller than scales; breast region oliveyellowish. Axil of pectoral fin dark, sometimes with a spot. Base of pectoral fin either whitish or same coloration as breast. Caudal blotch on both caudal fin and peduncle, two-thirds above lateral line.
Distribution. Atlantic drainages of Panama; Lake Gatún, rivers Mandinga, Chagres, Ipetí and others,
including areas formerly within the Canal Zone (Fig. 5).
Remarks. The list of objective synonyms underscores the obscurity in phylogenetic position of this species. It appears clear, nevertheless, that its resemblance to Neetroplus (=Hypsophrys) nematopus is a convergence (Rogers 1981, Schmitter-Soto, in press). The affinity with Cryptoheros was earlier recognized by
Kullander (2003), who considered it a species of Archocentrus. This relationship was overlooked by all previous workers, perhaps because of the low anal-fin spine count of Cr. panamensis, which is atypical for Archocentrus and related taxa (Table 3) and is approached only by Cr. sajica.

extending to distal third of caudal fin or beyond. One or two lateral-line pored scales on caudal fin; subsidiary
pores always present, occasionally forming two-scale rows. Scales between dorsal and anal fin rays distally in
two rows, up to 16 scales long.
Genital papilla oval, with pigment on margins and basal half, rarely also on tip.
A faint vertical bar on head, starting behind orbits; no interorbital bands; a stripe from snout to eye; no
opercular spots. Eyes golden-green. No longitudinal stripe, but said to have a blue streak in life. Second bar on

more on peduncle, one third or less on caudal fin; the blotch crosses the lateral line, and usually forms a saddle, i.e., blotch continuous across the dorsal part of the caudal peduncle but not across the ventral part.
Distribution. Endemic to rivers flowing into Lake Izabal, Guatemala (Fig. 5).
Remarks. Although earlier references (e.g., Schmitter-Soto 1998) have included this species in the Mexican fauna, Kullander (2003) correctly considered the species not to be present in Mexico. Alleged records
from that country are based on Cr. chetumalensis (see below). Costa Rican and Panamanian specimens originally identified as “Cichlasoma spilurum” at UMMZ (190367 and 147222) are Cr. septemfasciatus and Cr.
altoflavus, respectively. The Nicaraguan records mentioned by Allgayer (2001) and Kullander (2003) might
be Cr. cutteri (see below), but I was unable to locate any specimen of the subgenus Cryptoheros from Nicaragua.
Cichlasoma immaculatum, originally described as a “variety” of C. spinosissimum by Pellegrin (1904; see
above) is actually a junior synonym of Cr. spilurus. The two syntypes (MNHN 9846, Fig. 8), although decolored and partly descaled, are readily identifiable as Cr. spilurus based on meristic (e.g., A. IX, not A. XI;
scales between lateral line and first dorsal fin spine 4.5, not 5–6) and morphological grounds (e.g., the triple
coronal pore characteristic of Cryptoheros).
Cr. cutteri is removed from the synonymy of Cr. spilurus (see below).

ing rows; scales between dorsal and anal fin rays distally in two rows, up to 11 scales long; in juveniles, no
scales between anal fin rays.
In specimens above ca. 45 mm SL, gut of simple type but with two intermediate loops; anal and medial
loops twist and directed dorsad; anal and anterior esophageal loops adjacent. Peritoneum only dorsally pigmented, mainly on posterior half; black melanophores on tan background. Genital papilla oval or tongueshaped; some melanophores on its base, margins and posterior side, or none.

grey, or bluish; sometimes golden. No longitudinal stripe. Bars on side of body, medially more intense, especially at scale edges; no conspicuous alternation of intensity, except that 3rd bar most intense and 2nd bar least
intense; first bar I-shaped, somewhat inclined on head; 1st and 2nd bars may coalesce medially as a humeral
blotch, and 3rd bar may display an oval spot. Ocellus absent from dorsal fin. Bases of soft dorsal and anal fins
usually darkened; sometimes with rows of light dots discernible. Abdomen whitish or greyish in life, not
wine-colored (Fig. 10). Axil of pectoral fin somewhat darker than breast; base of pectoral fin usually white.
Caudal blotch either more on peduncle than on fin, or entirely on peduncle, oval in shape, extending from dorsum to abdomen; edge of blotch diffuse, usually not saddled, coalescent or not with last bar.
Distribution. Belize (Belize River) and the Guatemalan Petén (Río Sarstún) north to Quintana Roo, Mexico (as far north as Laguna Kaná, 19°30’N —ECOCH 1559) (Fig. 5).

Diagnosis. Autapomorphy (Schmitter-Soto, in press): a wine-colored abdomen in life (in adults). Bars on
sides of body with alternating intensity, the second one much lighter than first and third. Further distinguished
from other species in the subgenus by arms of first epibranchial bone, which are divergent (vs. parallel);
supraoccipital crest undulating (vs. straight); ventral angle of articular obtuse (vs. right-angled); absence (vs.
presence) of an anteriorly directed pronounced convexity on ventral process of articular; procurrent rays of
caudal fin 2 (vs. 3–4).
Description. D. XVII–XIX,9–11; A. VIII–X,7–9 (one specimen of 60 with 11 spines). Gill rakers on
lower limb of first arch modally 7. Scale rows on cheek 4–6; scales from lateral line to origin of dorsal fin 4–
6 (contra Fowler 1932, who counted 7); scales from lateral line to base of first dorsal-fin ray 2.5–3.5; circumpeduncular scales modally 18 (further meristic data appear in Table 3).
Largest examined specimen, 112 mm SL. Body depth (44–54%, usually greater than 49% of SL). Head
length 32–43% of SL (further morphometric data appear in Table 4). Head profile convex or straight, concave
above orbits. Teeth embedded; pointed or bluntish, slightly labiolingually compressed and retrorse, bicuspid.
Upper symphysial teeth subequal to adjacent teeth, not abruptly larger; lower symphysial teeth may be
slightly shorter than adjacent teeth. Upper lip medially narrow; lower lip squarish or rounded at corner, its
lower angle acute.
Pectoral and pelvic fins always reaching caudad beyond 2nd anal-fin spine. Filamentous rays of dorsal fin
at least to mid-caudal fin. Subsidiary pored scales on caudal fin always present, occasionally forming twoscale rows; scales between dorsal fin rays distally in two rows, up to 11 scales long.
In specimens from ca. 35 mm SL and larger, gut simple with two intermediate loops; medial and anal
loops twisted and directed dorsad. Peritoneum pigmented only dorsally (to half sides), mainly anteriorly; with
isolated blotches posteriorly. Genital papilla rounded, as long as broad, or oval, longer than broad or broader
than long; in some, the tip crenulated or notched; sunken; no pigment, except on margins, basal half, and posterior (caudal) side.
No vertical bar on head; no interorbital bands, but postorbital–nape region somewhat dark; a stripe from
snout to eye, sometimes diffuse; suborbital streak straight, sharp-ended; no opercular spots, but opercle dark,
except on postorbital region. Eyes blue-greenish. No longitudinal stripe. Bars on sides of body, medially much
more intense; 1st bar I-shaped, somewhat inclined on head; intensity alternating: 1st, 3rd, 5th, 7th bars, especially
3rd, much more intense than 2nd, 4th, 6th; 2nd, 4th bars may be dorsally evanescent; 3rd bar and sometimes also 5th
and 7th may extend slightly onto base of dorsal fin. An ocellus may be present on spinous dorsal fin of mature
females. Soft dorsal and anal fins usually immaculate; sometimes light dots discernible at bases. About 13
rows of light spots on sides, smaller than scales; breast region yellowish-greenish or olive (or “wood brown”
according to Fowler [1932]). Axil of pectoral fin somewhat dark (part of 1st bar); base of pectoral fin yellowish or white. Caudal blotch two-thirds or more on peduncle, across lateral line, usually forming a saddle.
Distribution. Atlantic Honduras (Ríos Celán, Lancetilla, Aguán, Jutiapa, and others) north to Guatemala
(Ríos Achuelo, Matasano, and others) (Fig. 5).
Remarks. Synonymized with Cichlasoma spilurum by Miller (1966) with no explicit justification. This
move was followed by Allgayer (2001), who added that the Honduran so-called “«Archocentrus» sp.
«Yojoá»” also belonged in Cr. spilurus, but acknowledged that “[p]lusieurs formes locales, notamment du
Honduras[,] sont connues.”
Fowler’s (1932: 381) figure is not accurate: it depicts the holotype as showing all the bars of approximately the same intensity, which is not the case (Fig. 11). The figure contains other errors, e.g. the size of the
scales on the breast, which are much smaller and numerous than shown. Fowler (1932) thought his new species was “[r]elated to Heros octofasciatus” and felt that he needed to compare Cr. cutteri with R. octofasciata,
not with Cr. spilurus.
I was unable to examine specimens of the “Río Papaloteca” Archocentrus (Velasco 2001) from northern
Honduras, but nearby specimens (from Río Jutiapa, UMMZ 228665) are identifiable as Cr. cutteri.

base of pectoral fin; mature females with a black ocellated blotch on dorsal fin (except Cr. sajica); lateral spot
oval or circular (not discernible from bar in Cr. sajica); caudal blotch often diffuse, ventrally triangular,
mainly on peduncle (except in Cr. sajica).
Distribution. Atlantic Panama and Atlantic and Pacific Costa Rica (Fig. 5).
Species composition. Five species: Cr. septemfasciatus, Cr. altoflavus, Cr. myrnae, Cr. nanoluteus, and
Cr. sajica.
Etymology. Gender masculine. Named in honor of William Bussing, arguably the most influential recent
ichthyologist in Costa Rica.

Lectotype. Herein designated as BMNH 1909.3.13.82 (Fig. 12), C. F. Underwood. Río Iroquois, Costa Rica.
The specimen, 69 mm SL, is the second largest individual in the type series, inasmuch as the largest syntype is
rather deformed.
Paralectotypes. BMNH 1909.3.13.83–91 (17, 60–100 mm TL), collected with lectotype.
Diagnosis. No unique autapomorphies, but the only species of Bussingius with symphysial teeth conical
rather than labiolingually compressed, and a caudal blotch both on fin and peduncle (vs. either exclusively on
the fin or on the peduncle). Further distinguished by bars on sides of body only medially (not dorsally) more
intense; anal creases 12–16, modally 14 (vs. 10–15, modally 11–13); and lower symphysial teeth bicuspidate,
with a small lingual cusp (also in Cr. altoflavus).
Description. D. XVII–XVIII,9–10 (one specimen of 20 with 8 rays); A. VIII–X,7–9. Gill rakers on lower
part of first arch modally 6; gill rakers trapezoidal, sometimes bifid. Scales strongly ctenoid. Predorsal scales
modally 13; pored lateral-line scales (not counting overlapping scales between the two segments of the lateral
line) modally 27; scales from lateral line to base of first dorsal-fin ray 2 or fewer (one specimen of 20 with
2.5); circumpeduncular scales 16–17, occasionally 18 (additional meristic data appear in Table 3).

darker in some specimens. Eyes dark, greenish or bluish. No longitudinal stripe. Bars on side of body with no
dorsal intensifications; diffuse, except for the medial darkening; 1st bar diffuse, Y- or V-shaped (inversely triangular), inclined on head; on the 3rd and often on the last bar the medial intensification forming a distinct oval
spot. Bars not extending onto dorsal fin. A dorsal blotch in females, starting on 8th or 9th spine, ending on 11th
or 12th. Soft dorsal and anal fins immaculate; their bases darkened. About 12 rows of light spots on sides,
smaller than scales, clearer on breast; breast, fins and throat yellowish-olive. Axil of pectoral fin either dusky
or with same coloration as breast; base of pectoral fin whitish. Caudal blotch more on peduncle than on fin,
occasionally entirely on peduncle; always ventrally pointed, its edge diffuse.
Distribution. Atlantic Costa Rica, Río Banano to Río San Juan, at the Nicaraguan border (Fig. 5).
Remarks. Regan (1908) considered this species to be “very close to C. spilurum.” Misidentifications are
common; many museum specimens of the other species in the subgenus are determined as Cryptoheros sep-

Río Caña, an affluent of Río Cañaveral.
Diagnosis. No unique autapomorphies. Breast, fins and throat yellowish (vs. greyish or strongly yellow in
other species of Bussingius); basal process on the largest first-arch gill-rakers; lower symphysial teeth bicuspidate, with a small lingual cusp (also in Cryptoheros septemfasciatus); distally two rows of interradial scales
on anal fin (also in Cr. nanoluteus); spots on opercle, part of a rather indistinct longitudinal stripe.
Description. D. XVII–XVIII,9–10; A. VIII–IX,7–9. Gill rakers on lower part of first arch 6; gill rakers
distally expanded, sometimes bifid. Scales strongly ctenoid. Predorsal scales modally 14; pored lateral-line
scales (not counting scales overlapping between the two segments of the lateral line) modally 28; scales from
lateral line to base of first dorsal-fin ray 2.5; circumpeduncular scales 17 (other meristic data appear in Table
3).
Largest specimen examined, 90 mm SL. The deepest-bodied species of subgenus Bussingius, depth 45–
56% of SL, mean 53% of SL; head length 31–36% of SL (this trait not diagnostic vs. Cr. nanoluteus, contra
Allgayer 2001); orbital diameter 22–35% of head length (further morphometric data appear in Table 4). Head

retrorse. Upper symphysial teeth, often one larger than the other; the smaller upper symphysial tooth not
abruptly larger than adjacent tooth; lower symphysial teeth subequal to adjacent teeth. Lips not narrow medially; lower lip slightly tapering or not, squarish at corner.
Pectoral fins always reaching caudad beyond 2nd anal-fin spine; pelvic-fin filamentous rays always reaching beyond 4th and sometimes to 9th anal-fin spine. Filamentous rays of dorsal fin to distal quarter of caudal
fin. Two pored scales continuing lateral line on caudal fin, subsidiary scales present. Interradial scale rows of
dorsal and anal fins imbricated (i.e. with supplementary scales), up to 7 scales long.
Gut simple, with a secondary medial loop. Genital papilla tongue-shaped or rounded, notched, longer than
wide, wider at base, pigmented on base, sides, and posterior (caudal) face.
No vertical bar on head, but lower half of opercle darker; opercular spot usually distinct, forming part of
longitudinal stripe from opercle to pectoral-fin origin. Eyes greenish, greyish, or bluish. Bars on side of body
diffuse; 1st bar V-shaped with coalescent arms, like an inverted triangle, inclined on head; 2nd and 3rd intensified medially, all intensified dorsally; 5th and 6th more marked; medial intensification of 3rd bar an oval spot.
Bars not extending onto dorsal fin. Ocellus on dorsal fin of mature females starting on 6th or 7th spine, ending
between 10th and 13th spines. Soft dorsal and anal fins immaculate; their bases darkened. About 9 rows of light
spots on sides, smaller than scales; breast, fins and throat yellowish. Axil of pectoral fin somewhat dark, surrounded by a lighter ring; base of pectoral fin whitish. Caudal blotch more on peduncle than on fin, occasionally entirely on peduncle, across lateral line, saddled or diamond-shaped (always pointed ventrally), its edge
diffuse.
Distribution. In addition to the type locality, also known from Río Cricamola at Konkintu, Panama, a
new record that extends the range of the species westward (Fig. 5).
Remarks. Allgayer (2001) counted 15 abdominal + 15 caudal vertebrae, whereas I count 13+16 (also on
the published radiograph, ibidem); the present redescription is also at variance with the original description
with regard to other meristic data.
The collectors believed the species to be absent from the Río Cricamola “d’après les Indiens.” The Cricamola specimens of Cr. altoflavus approach Cr. nanoluteus in some characters, notably in body depth and
shape of caudal blotch.

Diagnosis. No unique autapomorphies, but distinguished from other species of the subgenus Bussingius
as follows: upper symphysial teeth usually abruptly larger than adjacent teeth (vs. not abruptly larger); gill
rakers on first arch digitiform, blunt (vs. trapezoidal or bifid); a diffuse but complete longitudinal stripe, ending in a tenuous blotch on the caudal peduncle (vs. on the fin); lateral spot circular (vs. oval); predorsal scales

(not counting scales overlapping between the two segments of the lateral line); scales from lateral line to base
of first dorsal-fin ray 1.5–2.5; circumpeduncular scales 16–18 (further meristic data appear in Table 3).
FIGURE 14. Cryptoheros myrnae, holotype, AMNH 59079. Photo, M. Stiassny.
Largest specimen examined, 68 mm SL (maximum size 80 mm SL: Kullander 2003). The most slender
species of Bussingius, depth 42–50% of SL; head length 33–37% of SL; orbital diameter 25–30% of SL (other
morphometric data appear in Table 4). Head profile straight above orbits, convex on nape. Teeth not embedded; labiolingually compressed, the sides not concave. Upper symphysial teeth usually abruptly larger than
adjacent teeth; lower symphysial teeth subequal to adjacent teeth. Lips medially narrow; lower lip slightly
tapering or not, rather square at corner; often with fleshy hair-like protuberances on lower lip.
Pectoral and pelvic fins always reaching caudad beyond 3rd anal-fin spine. Filamentous rays of dorsal fin
extending to mid-caudal fin. One or two pored scales of lateral line continuing onto caudal fin; usually no subsidiary scales present elsewhere between caudal-fin rays. Interradial scale rows on dorsal and anal fin imbricated (i.e. with supplementary scales), up to 6 scales long.
Gut simple, with secondary loops. Peritoneum heavily pigmented dorsoanteriorly. Genital papilla globose
and distally pigmented in females, tip triangular and immaculate in males.
No interorbital bars, but snout darkened; suborbital streak, if visible, posteriorly sharp; opercular spot usually not distinct. Eyes metallic blue in life. Longitudinal stripe diffuse but complete, extending from orbit to
caudal fin. Bars on side of body diffuse, sometimes absent or incomplete; 1st bar V-shaped with coalescent
arms, like an inverted triangle, inclined on head; medial intensification of 3rd bar a circular spot. Bars not
extending onto dorsal fin. Ocellus on dorsal fin of mature females starting on 8th or 9th spine and ending
between 11th and 13th spine. Three hyaline rows of dots on soft dorsal fin, iridescent blue in life. About 6 rows
of light spots on sides (golden in life in thoracic region), smaller than scales; breast and throat orange in life; a
black triangular region ventral to pectoral fin in females. Axil of pectoral fin somewhat dark to black; base of
pectoral fin whitish. Caudal blotch mainly on peduncle, situated across lateral line; coalescent with last bar
and pointed ventrally.
Distribution. Atlantic Central America, from Río Guarumo, Panama, to Río Estrella, Costa Rica (Fig. 5).
Remarks. Cr. myrnae is replaced by Cr. septemfasciatus north of the Río Estrella (Bussing 1998). Specimens of Cr. myrnae have, in the past, been used to demonstrate the supposed variability of Cr. septemfasciatus
(Bussing 1978).

Diagnosis. No unique autapomorphies, but the only Bussingius with at least the third (main) lateral bar
uniformly wide (its width not uniform in other species); usually no caudal blotch, no lateral spot or medial
intensification of bars on side of body, no ocellus on dorsal fin, no abdominal blackening in mature females;
palatine arms subequal (vs. anterior longer); posteriad projection on ventroposterior angle of retroarticular
absent (vs. present); articular with a right angle ventrally (vs. obtuse); an anteriorly directed pronounced convexity on ventral process of articular present (vs. absent); anal-fin spines modally 7 (vs. 8–9).
Description. D. XVII–XVIII,9–10; A. VI–VIII,7–8. Gill rakers on lower limb of first arch 6; larger gill
rakers bifid or at least distally expanded, trapezoidal, some digitiform. Scales moderately ctenoid. Predorsal
scales modally 14; pored lateral-line scales (not counting scales overlapping between the two segments of the
lateral line) 27–28; scales from lateral line to base of first dorsal-fin ray 2 or fewer; circumpeduncular scales
16–18 (additional meristic data appear in Table 3).
Largest specimen examined 53 mm SL (maximum size 90 mm SL: Kullander 2003). Body depth 46–49%
of SL; head length, 34–37% of SL; orbital diameter 28–31% of head length (further morphometric data appear
in Table 4). Head profile nearly straight to convex. Teeth not embedded; conical, labiolingually compressed.
Upper symphysial teeth not abruptly larger than adjacent teeth, but not subequal either; lower symphysial
teeth subequal to adjacent teeth. Upper lip normal or medially narrow; lower lip square squarish at corner,
often tapering.
Pectoral fins always reaching caudad beyond 2nd, pelvic fins beyond 3rd anal-fin spine. Filamentous rays of
dorsal fin to mid-caudal fin or beyond. Up to two lateral-line pored scales on caudal fin, subsidiary scales usually present. Dorsal-fin interradial scale rows, not imbricated (i.e. with no supplementary scales), up to 5 or 6
scales long.
Gut simple. Genital papilla tongue-shaped, oval, sunk; sometimes twice as long as broad; pigmented on
margins and tip.
No definite vertical bar on head; no interorbital bands; suborbital streak present; no stripe from snout to
eye; no opercular spot. Eyes blue with a golden rim (more noticeable in life). No longitudinal stripe. First bar
on side of body, rather V-shaped, but diffuse; 3rd bar best defined and uniformly wide; 3rd and 6th bars extend
onto dorsal fin, but there is no dorsal (female) spot. Hints of 2–3 spot rows on soft dorsal. About 11 rows of
spots on sides, smaller than scales and located on the scale rim; breast beige. Axil of pectoral fin with a dark
dorsal spot; base of pectoral fin paler than breast. Caudal blotch tenuous or absent, rather a dark region on
base of fin, not on peduncle.
Distribution. Río Parrita to Río Coloradito, Pacific versant of Costa Rica (Fig. 5).
Remarks. Without a cladistic analysis, Bussing (1974) hypothesized the species to be the Pacific sistergroup of the Atlantic Cr. septemfasciatus; my analysis could not support this assertion. However, several character states of Cr. sajica are plesiomorphic (Schmitter-Soto, in press), which suggests that the species could be
basal in Bussingius. The rest of the species in the subgenus are distributed in the Atlantic versant.

Type species. Heros nigrofasciatus Günther, 1867, by original designation.
Diagnosis. Three strict synapomorphies (Schmitter-Soto, in press): first bar on side of body, Y-shaped, wellmarked, caudal arm discontinuous; bars from sides of body extending fully to the edge of dorsal and anal fins;

medial intensifications on 2nd and 3rd bars, sometimes also on 1st. Differs from most other heroine genera also
as follows: mouth terminal (also in Cryptoheros and Ar. multispinosus); spots on opercle part of vertical bar
on head (also in Caquetaia and H. nematopus), which extends fully across opercle (also in Rocio and Archocentrus); three procurrent rays on caudal fin (also in most Cryptoheros, Petenia, and Tomocichla); dentary
symphysial teeth lower than adjacent teeth (also in Rocio, Cr. panamensis, and Petenia—not so abruptly lower
as in Parachromis); premaxillary symphysial teeth abruptly larger than adjacent teeth (also in Rocio, Parachromis, Cr. myrnae, and Caquetaia); ascending premaxillary arm reaching only to anterior orbit rim (also in
Rocio); maxilla dorsally serrated (also in Cryptoheros and Tomocichla).
Description. D. XVII–XIX,7–10 (up to 11 in Am. kanna); A. VIII–X (to XI in Am. siquia and Am.
kanna),6–8 (to 9 in Am. siquia); first dorsal fin ray divided. Gill rakers on lower limb of first arch 5–8, total
gill rakers 7–11; gill rakers trapezoidal or bifid, with a basal process. Scales strongly ctenoid. Scale rows on
cheek 4–6; pored lateral-line scales (not counting scales overlapping between the two segments of the lateral
line) 25–29; scales from lateral line to first dorsal fin spine 4–5.5, rarely 3.5; scales between vent and interpelvic scale 6–12. Lower jaw external teeth 22–24. Anal creases modally 14.
Maximum size, less than 100 mm SL. Body rather oval, depth 43–58% of SL. Maxilla reaching only to
ventral rim of orbit, not to a vertical from anteriormost rim (except in some specimens of Am. nigrofasciata);
premaxillary dorsal process extending only to anterior rim of orbit; mouth terminal or lower jaw protruding
slightly; frenum present in lower lip; teeth moderately embedded, occasionally with a small lingual cusp,
lower symphysial teeth lower than adjacent teeth; pectoral and pelvic always reaching anal-fin origin and usually to 7th anal-fin spine; in Am. kanna and Am. siquia, pelvic fins may extend caudad to 10th anal-fin spine.
Origin of pelvic fin behind origin of dorsal fin. Caudal fin rounded-truncate. Interradial scale-rows in dorsal
and anal fins, up to 7–8 scales long (to 11 in Am. kanna). In gut, anal loop and rostral esophageal loop adjacent. Genital papilla oval, in females opening oval, not much crenulated. Seven bars on sides, first bar clearly
Y-shaped, medial intensifications on 2nd and 3rd bars, and sometimes also on 1st bar; no speckles on cheek; no
interorbital bars, or diffuse; a sharp vertical bar on head, across all of opercle and nape, coalescent with opercular spots; no longitudinal stripe on body; no abdominal black blotch on females; caudal blotch entirely or
mostly on fin (sometimes obsolescent), across lateral line, not ocellated.
Distribution. From Panama (Atlantic) to Guatemala (Atlantic and Pacific) (Fig. 17).
Species composition. Four species: Am. nigrofasciata, Am. coatepeque, Am. kanna, Am. siquia.
Etymology. Gender feminine, derived from the type locality of the type species; “Amatitlán” means “a
place abundant in amate” in Nahuatl, “amate” being a kind of rustic paper made from the bark of Ficus petiolaris or F. indica (León-Portilla 1959).
Remarks. Regan (1908) suspected a relationship between Amatitlania and Rocio. The genus does show
putative synapomorphies with Rocio and Cryptoheros, but the cladistic analysis (Schmitter-Soto, in press) did
not find substantial support for such a clade.

Paralectotypes. BMNH 1865.4.19.77–78 (12), ZMB 6882 (1). There were several syntypes, not only one
(see Remarks).
Diagnosis. No unique autapomorphies, but the only species in the genus with two (vs. one) distal rows of
interradial scales on anal fin, and arms in the first epibranchial bone parallel (vs. divergent). In addition, posterior end of dentigerous arm of dentary rounded or squarish (vs. triple-spined or bluntly pointed). Peritoneal
coloration uniformly dark (vs. not uniformly dark). Rostrad directed pronounced convexity on the ventral process of the articular absent (vs. present). Also morphometric differences (body less deep) vs. Am. kanna and
Am. siquia, and coloration differences (4th bar not Y-shaped) vs. Am. coatepeque.
Description. D. XVII–XIX,7–9; A. VIII–X,6–7. Larger gill rakers elongated, rounded or pointed, curved
ventrad. Scales from lateral line to base of first dorsal-fin ray modally 2.5; circumpeduncular scales usually
17–19, modally 18; total vertebrae 27–28 (further meristic data appear in Table 3).
Largest specimen examined 88 mm SL (maximum size 100 mm SL, according to Kullander 2003). Body
depth 46–50% of SL, usually less than 48% of SL (further morphometric data appear in Table 4). Head profile
nearly straight on orbits to convex on nape. Teeth conical, pointed. Upper symphysial teeth abruptly larger
than adjacent teeth; lower symphysial teeth lower than adjacent teeth. Lips not medially narrow; lower lip
often tapering, corner dorsally rounded, ventrally angled.

FIGURE 18. Amatitlania nigrofasciata, lectotype, BMNH 1865.4.19.76. Photo, BMNH, London.
Pectoral fins always reaching caudad beyond 2nd anal-fin spine, pelvic fins extending beyond 3rd anal-fin
spine. Filamentous rays of dorsal fin to distal quarter of caudal fin. Up to two lateral-line pored scales on caudal fin, subsidiary scales usually present. Dorsal- and anal-fin interradial scale rows arranged in one or two
rows, up to 8 scales long (contra Günther 1869, who found the soft dorsal and anal fins to have “scarcely any
scales on their base”).
Gut simple, usually shorter than standard length of fish. Peritoneum silvery. Genital papilla tongueshaped, somewhat oval-tubular, slightly notched, tip bluntly triangular, not sunken; pigmented on margins,
tip, and base on posterior (caudal) side.
Suborbital streak diffuse; stripe from snout to eye usually diffuse. Eyes bluish-green. Fourth bar on side of
body I-shaped. Ocellus on spinous dorsal fin of females absent (present in 0.3% of the specimens examined).
Breast olive. Axil of pectoral fin dark; base of pectoral fin usually definitely white. Caudal blotch present as a
bar on fin, not on peduncle.
Distribution. The range of this species is restricted as follows: Pacific slope, from Río Sucio, El Salvador
to Río Suchiate, Guatemala; Atlantic slope, from Río Patuca, Honduras to Río Jutiapa, Guatemala; in neither
slope to Panama, Costa Rica or even Nicaragua, as formerly considered. Those southern populations, and the
one isolated at Lake Coatepeque, El Salvador, belong to the three species described below (Fig. 17). Introduced elsewhere, e.g. in the Río Balsas basin, central Mexico (Contreras-Balderas 1999).
Remarks. Günther (1867) mentioned both lakes, Amatitlán and Atitlán, as the type locality; however, the
original labels of the syntypes at BMNH mention only Lake Amatitlán, same as did Günther (1869). On the
other hand, Eschmeyer (2005) mentions just two British syntypes, but there are 13 specimens in the jar (plus
one skeleton), and Günther (1867) wrote: “numerous examples…were collected by Mr. Salvin.”
The extensive experimental (ethological, physiological, etc.) literature mentioning Archocentrus nigrofasciatus or Cichlasoma nigrofasciatum should eventually be revised regarding the origin of the material used
(see Distribution). The same applies to the study of biological invasions by the “convict cichlid,” considered a
potential pest outside its natural range (Welcomme 1988).

Paratypes. FMNH 12136 (10), island in Lake Coatepeque; UMMZ 181823 (18), 202805 (4), Santa Ana,
eastern coast of Lake Coatepeque at Monterrey.
Diagnosis. Unique autapomorphies (fig. 24h in Schmitter-Soto, in press): fourth bar on side of body Yshaped (formed by ventral coalescence of 4th and 5th bars) (vs. I-shaped); posterior end of dentigerous arm of
dentary triple-spined (vs. rounded), squarish or bluntly pointed; and a characteristic double medial-loop in gut
present (vs. absent). Differs from the other Amatitlania species also by posteriad projection at dorsal corner
present in lower lip (vs. absent), peritoneal pigmentation uniformly sparse (vs. uniformly dark or silvery), and
scales from lateral line to origin of dorsal fin 5–5.5 (vs. 5 or fewer).
Description. D. XVII–XIX,7–9; A. VIII–X,6–7. Scales from lateral line to first dorsal fin ray modally 2;
circumpeduncular scales usually 17–18; total vertebrae 28 (additional meristic data appear in Table 3).
Largest specimen examined 91 mm SL. The most slender Amatitlania, body depth 43–48% of SL, usually
less than 47% of SL (further morphometric data appear in Table 4). Head profile concave to straight on orbits
to convex on nape. Teeth conical. Upper symphysial teeth usually subequal to adjacent teeth. Upper lip medially narrow; lower lip tapering or not, rounded at corner, sometimes with a dorsal posteriad projection.
Pectoral and pelvic fins sometimes not reaching 1st anal-fin spine, but usually extending caudad beyond 2nd
anal-fin spine Filamentous rays of dorsal fin to end of caudal fin. One or two pores continuing lateral line on
caudal fin, subsidiary scales forming rows between other caudal-fin rays. Dorsal-fin interradial scales
arranged in one row, anal-fin scales in one or two rows, both up to 8 scales long.
Gut simple with a double medial-loop and the anal loop turned dorsad, always longer than standard length
of fish. Peritoneum with uniformly distributed melanophores among others, larger, fewer, aligned with ribs; in
young, only rostrally pigmented. Genital papilla elongated, contours parallel, end somewhat crenulated; pigmented on margins, base, tip, and posterior (caudal) side.
No suborbital streak discernible; stripe from snout to eye usually diffuse. Head bar darkening the whole
opercle, except for area rostral to lateral line. Eyes bluish-green. Bars on side of body more intensely black

than other Amatitlania; 4th bar Y-shaped, coalescent ventrally with 5th. Sometimes three rows of hyaline spots,
on tip of soft dorsal and base of soft anal fins. Breast olive-blackish. Axil of pectoral fin dusky; base of pectoral fin whitish or with same coloration as breast. Caudal blotch present as a bar on fin, not on peduncle, nearly
all across the depth of the fin.
Distribution. Known only from the type locality, Lake Coatepeque, El Salvador (but see Remarks) (Fig.
17; photographs in Hildebrand 1925, his figs. 3 and 4).
Etymology. Coatepeque is the name of the lake where the species occurs, likely formed from the Nahuatl
cóatl=snake and tépetl=mount, hence “mount of the snake.” A noun in apposition.
Remarks. In his study of Salvadorian fishes, Hildebrand (1925) included specimens of Cichlasoma
nigrofasciatum from Lake Coatepeque; the species was “especially abundant among the rocks where, because
of the very clear water, it could be seen at a depth upward of 6 meters.” He noted that “some specimens are
much darker than others”, and that the natives called the light variety “plateada” (silver) and the dark one
“negra” (black). Am. coatepeque has much more intense bars on side of body than other Amatitlania species.
The population at Lake Chalchuapa, El Salvador (FMNH 12139), although identifiable on other respects
as Am. nigrofasciata, displays in 2 of 7 individuals the Y-shaped 4th bar characteristic of the new species. The
site is near Lake Coatepeque, and may have been connected to it in the past. The above mentioned “plateada”
and “negra” forms coexist at Chalchuapa (Hildebrand 1925).

Diagnosis. No unique autapomorphies, but differs from all other Amatitlania by secondary caudal pores
absent (vs. present), peritoneum pigmented dorsolaterally (vs. uniformly), and quadrate bone wider than long
(vs. not wider than long). Several features shared with Am. siquia (body relatively deeper, fewer circumpeduncular scales), some of them synapomorphies (Schmitter-Soto, in press): gill-rakers on first arch often bifid
(vs. trapezoidal); caudal edge of urohyal sigmoid (vs. concave); anterodorsad spine on first dorsal pterygiophore present (vs. absent). However, it differs from its sister species as follows: dorsal-fin interradial scales
distally in two rows (vs. one); posterior edge of mesethmoid rounded (vs. straight-irregular); gut simple (Sshaped, not folded anal and medial loops touching) (vs. shaped like an S folded ventrorostrally in adults, anal
and medial loops not touching); and caudal blotch completely on fin (vs. partly on peduncle).
Description. D. XVII–XIX,8–10 (one specimen of 19 with 11 dorsal fin rays); A. IX–X,7–8. Gill rakers
trapezoidal or bifid. Scales from lateral line to first dorsal-fin ray modally 2; circumpeduncular scales usually
16–17, modally 16; total vertebrae 27 (further meristic data appear in Table 3).
Largest specimen examined, 83 mm SL. The deepest-bodied Amatitlania, body depth 48–58% of SL, usually greater than 50% of SL (further morphometric data appear in Table 4). Head profile concave on orbits,
convex on nape. Teeth conical, pointed, slightly retrorse. Upper symphysial teeth abruptly larger than adjacent
teeth. Upper lip medially narrow; lower lip often with fleshy, hair-like papillae, not tapering nor squarish at
corner, its lower angle acute.
Pectoral fins always reaching caudad beyond 2nd anal-fin spine pelvic fins always extending beyond 5th
and often to 10th anal-fin spine. Filamentous rays of dorsal fin reaching to distal third of caudal fin. One or two
pores continuing lateral line on caudal fin, no subsidiary scales. Dorsal-fin interradial scales arranged distally
in one or two rows, up to 12 scales long; anal-fin scales usually in one row, up to 9 scales long.
Gut simple, usually slightly shorter than standard length. Peritoneum pigmented only dorsally, less so on
upper sides. Genital papilla oval, but often distally expanded; uniformly pigmented on base.
Suborbital streak present; stripe from snout to eye usually well defined. Head bar interrupted in an area
rostral to lateral line. Eyes blue with a golden rim. Bars on side of body sharp, medially and dorsally more
intense; 4th bar I-shaped. No dots discernible on soft dorsal and anal fins. Breast olive. Axil of pectoral fin
with same coloration as breast or dark, often with a dorsal spot; base of pectoral fin whitish. Caudal blotch on
fin, across lateral line; often saddled.
Distribution. From rivers Cañaveral, Cricamola, Sixaola, and other localities in Atlantic Panama (Fig.
17).
Etymology. Greek κάννα, meaning “a reed”, Río Cañaveral (= reedbed) being the first locality where the
species was detected (see Remarks). A noun in apposition.
Remarks. The species was first recognized as distinct by Allgayer (2001: 18), who called his specimens
from Río Cañaveral “Cryptoheros cf. nigrofasciatus.”

rostrally pigmented (vs. not only rostrally pigmented). Further distinguished from all other Amatitlania as follows: caudal blotch about two-thirds on peduncle and one-third on fin (vs. completely on fin); posterior edge
of mesethmoid straight-irregular (vs. rounded); scales from lateral line to base of first dorsal fin ray modally
1.5 (vs. modally 2 or more); caudal vertebrae modally 14 (vs. modally 13).

1.5; circumpeduncular scales usually 15–17, modally 16; total vertebrae 26–27 (additional meristic data
appear in Table 3).
Largest specimen examined, 79 mm SL. A deep-bodied Amatitlania, body depth 48–55% of SL, usually
greater than 49% of SL (further morphometric data appear in Table 4). Head profile straight to convex. Teeth
conical, pointed, slightly or not labiolingually compressed. Upper symphysial teeth abruptly larger than adjacent teeth. Upper lip medially narrow; upper angle of lower lip at corner much rounded, lower angle acute,
tapering ventrad.
Pectoral fins always reaching caudad beyond 3rd, pelvic fins always beyond 5th anal-fin spine and often to

bands sometimes not so diffuse. Head bar more intense dorsally. Eyes bluish, greenish, greyish. Bars on side
of body ventrally more obsolescent and coalescent than in other species; 4th bar I-shaped. Dots sometimes discernible on bases of soft dorsal and anal fins. Breast olive. Axil of pectoral fin with a dorsal dark spot; base of
pectoral definitely white. Caudal blotch two-thirds on fin, more dorsal than ventral to lateral line, never to
ventral edge, oval.
Distribution. Both coasts of Costa Rica (from tributaries to the Golfo de Nicoya on the Pacific coast and
Río Parismina on the Atlantic) to Nicaragua (including the Great Lakes and the Mosquitian basins); also north
to Atlantic Honduras (Río Yeguaré) (Fig. 17).

Description. D. XVII–XIX,8–10, modally 10 (7 of 174 with 11 dorsal fin rays); A. VIII–IX,7–9, modally
8 (2 of 177 with 6 or 7 anal-fin spines); pectoral 14–16. Gill rakers rounded, distally expanded or trapezoidal,
sometimes bifid and even trifid, sometimes serrated. Scale rows on cheek modally 6 (4–7, 12 of 68 specimens
with 7 scale rows); predorsal scales modally 12; pored lateral-line scales (not counting scales overlapping
between the two segments of the lateral line) 27–30; scales from lateral line to origin of dorsal fin 4–5.5;
scales from lateral line to base of first dorsal-fin ray 3–4 (further meristic data appear in Table 3).
Largest specimen examined, 217 mm SL, but reported to 250 mm SL (Page & Burr 1991). Body usually
slender, deeper in young (39–51% of SL). Head length 33–42% of SL; orbital diameter usually 21–25% of
head length (up to 31% of head length in juveniles—further morphometric data appear in Table 4). Head profile convex, straight, concave on orbits. Maxilla reaching only a horizontal line, not a vertical, from orbit. Corners of lower lip slightly tapering, if at all.
Pectoral and pelvic fins nearly always reaching caudad beyond 1st or 2nd anal-fin spine (not reaching in 2
of 127 specimens). Filamentous rays of dorsal fin to mid-caudal fin. Scales between dorsal and anal fin rays in
one row, up to 6 scales long.
Gut simple, anal and anterior esophageal loops adjacent; gut length shorter or subequal to standard length
of fish. Genital papilla thick, cylindrical, notched or triangular-tipped, sometimes sunk, longer than broad,
medially swollen, somewhat crenulate at tip, sometimes rather vase-shaped; pigmented just in basal half and
margins, if at all.

in preserved specimens). Eye color varied: yellowish, greyish, bluish, coppery, reddish. Bars on sides sometimes diffuse, sporadically dorsally or medially coalescent. Lateral blotch oval to squarish, joining 3rd and 4th
bars, sometimes not discernible from longitudinal stripe. About 15 rows of light spots on sides, centered in
each scale, not always visible; breast region olive. Axil of pectoral fin with same coloration as breast or
dusky; base of pectoral fin paler than surrounding region. For life colors, see Fig. 24.

FIGURE 24. Rocio octofasciata live. Locality: Arroyo Tres Garantías, Quintana Roo, Mexico. Photo, H. Bahena.
Distribution. From Río Ulúa, Honduras (Lee et al. 1980), to tributaries of Río Actopan, Veracruz, Mexico (Greenfield & Thomerson 1997) (Fig. 22). Introduced in several localities in northern Veracruz (Obregón
et al. 1994).
Remarks. Contra Regan’s (1903) original designation (and S. Fisch–Müller’s opinion, pers. com.), Mahnert (1976: 44) treated the nine specimens originally in MHNG 665.55 as syntypes. However, there is little
doubt that the largest individual is the holotype. The confusion was likely created by Regan (1904, 1905) himself, when he added material to his successive redescriptions, somewhat more accessible than the original
description.
Cichlosoma biocellatum, based on an aquarium specimen, is a synonym, its type locality (“Río Negro at
Mañaos [sic], Brazil”) certainly in error.
Cichlasoma hedricki was synonymized by Regan (1905), barely one year after Meek’s (1904) description,
without explicit reasons. The action was followed by most authors. Topotypes of C. hedricki (from the upper
Papaloapan) tend to be deeper-bodied than other R. octofasciata, and the presence of a prominent lingual cusp
in their symphysial teeth (fig. 15a in Schmitter-Soto, in press) tends to be more constant, but the forms merge
imperceptibly towards the type locality of R. octofasciata in the Coatzacoalcos, the drainage immediately to
the south of Papaloapan.
In print, Meek (1904) called the type locality of C. hedricki “Obispo, Veracruz;” however, his manuscript
label in the paratype jar at UMMZ (176671) reads “Río Obispo, Oaxaca.” The eight paratypes in this lot
(labelled as such by Meek himself) should probably be added to the 44 specimens mentioned by Eschmeyer
(2005); however, on the other hand, the original description mentions only one “type,” thus rendering the literature (and paratype holdings at UMMZ and FMNH) in error.

almost completely black specimens. Lateral blotch rather rounded. 12–16 rows of light spots on sides, centered in each scale, not always visible; breast region bronze-yellowish or blackish. No clear dots or streaks on
anal fin. Axil of pectoral fin with same coloration as breast or dusky; base of pectoral fin pale; isolated melanophores on pectoral ray inner (posterior) bases. Abdomen reddish in life (Stawikowski & Werner 1998).
Distribution. Probably endemic to Laguna Ocotal, a rather isolated, highland water body in the LacantúnUsumacinta drainage, Chiapas, Mexico (Fig. 22—pictures in Miller 1957).

Etymology. From the Spanish “ocotal,” meaning “an ocote forest,” “ocote” being a species of Pinus; the
name of the lake where the species lives. A noun in apposition.
Remarks. The view that the Ocotal population is in fact a new species was already expressed nearly 50
years ago (Miller 1957). This is one of the many species in several families that the late Dr. Miller detected as
new, but did not get to describe (Hendrickson et al. 2002).

and a horizontal line from orbit (vs. just to the ventral rim); cheek-scale rows modally 7 (vs. 6 or fewer); interradial scales on dorsal fin in one row (vs. distally in two rows); dorsal and anal fins not bearing filaments (vs.
bearing filaments); anal and medial gut-loops not adjacent, well separated by the stomach and the liver (vs.
always adjacent); rostral end of maxilla notched or at least concave (vs. convex, with no notch); caudal ocellus blue in life (vs. white).

Species composition. Two species, H. nicaraguensis and H. nematopus.
Remarks. Neetroplus is hereby synonymized, so Hypsophrys is no longer monotypic. The other species
assigned to Neetroplus by some recent authors, Cr. panamensis, is here regarded to belong in Cryptoheros (see

FIGURE 28. Hypsophrys nicaraguensis, holotype, BMNH 1867.9.23.37. Photo, BMNH, London.
Diagnosis. Unique autapomorphies (Schmitter-Soto, in press): first dorsal fin ray spiniform; pharyngeal
jaws 19 teeth rows wide, 11 rows long; gill rakers on lower limb of first arch modally 9. Easily distinguished
from the other species in the genus by the pointed jaw teeth and the strongly convex head profile (“Coryphaena-like”—Günther 1869), among many other differences.
Description. D. XVIII–XIX (modally XIX),9–11; A. VII–VIII,7–9 (modally VIII,8); pectoral 15–16.
First dorsal fin ray not divided. Gill rakers on lower limb of first arch 9–10; gill rakers long, arched, may be
bifid. Subsidiary pored scales on caudal fin in two long rows between rays. Scale rows on cheek 4–5 (contra
Günther 1869, who counted 6); pored lateral-line scales (not counting scales overlapping between the two
segments of the lateral line) 31–33; scales from lateral line to origin of dorsal fin 5–5.5; scales from vent to
interpelvic scale 9–12; anal creases modally 12 (additional meristic data appear in Table 3).
Largest specimen examined, 141 mm SL, but grows at least to 165 mm SL (Kullander 2003). Body depth
44–46% of SL (further morphometric data appear in Table 4). Teeth moderately embedded, at least lateral
teeth; symphysial teeth small, conical, narrow, slightly retrorse; upper symphysial teeth not abruptly larger
than adjacent teeth, lower subequal. Lips not medially narrow; lower lip at corner of mouth square-rounded or
slightly tapering.

vic fins always reaching at least to 3rd anal-fin spine. Caudal fin profile emarginate to subtruncate. Scales
moderately ctenoid, rather deciduous.
Gut simple; gut length ca. 80% of SL. Genital papilla rounded, wider than long, almost triangular, may be
smaller than creased area of anus; immaculate or a few melanophores on basal margins.
No stripe from snout to eye. Eyes greenish. Six bars on sides, diffuse; a conspicuous, rounded lateral
blotch, on 4th bar; a diffuse longitudinal bar from orbit to caudal fin, in which there may be a faint blotch on
fin, above lateral line (often absent). Dots on fins (often not noticeable in young). Rows of spots on sides 13–
15, smaller than scales; breast olive-yellowish. Axil of pectoral fin darkened, especially dorsally; base of pectoral fin whitish.
Distribution. Ríos Sapoá, Pizote, and Chirripó-Matina, Costa Rica, north to lakes Managua and Nicaragua and Río Coco, Nicaragua (Fig. 28).
Remarks. The list of objective synonyms highlights the uncertain generic affinities of the species. However, its relationship to H. nematopus is supported not only by the present morphological study, but also by
several recent molecular phylogenies (Martin & Bermingham 1998; Hulsey et al. 2004; Concheiro Pérez et al.
2007).
The entire original description of H. unimaculatus Agassiz, 1859 from Lake Nicaragua gives no other
detail but that it “resembles Chrysophrys” (= Sparus aurata Linnaeus), a Mediterranean and north Atlantic
coastal fish (Eschmeyer 2005). Nevertheless, Kullander and Hartel (1997) explained how this simple statement leaves no doubt that the species involved is H. nicaraguensis (the only species in Lake Nicaragua to
have an oval lateral blotch similar to that of Chrysophrys).
Because there are no types of H. unimaculatus and the name constitutes a senior synonym unused after
1899 (ICZN 1999), I shall file a petition to ICZN to conserve the younger specific epithet nicaraguensis.

Diagnosis. Many unique autapomorphies (fig. 6c in Schmitter-Soto, in press): Teeth properly incisor,
even in young; caudal edge of mesethmoid with a sui generis shape; caudal edge of supraoccipital crest
straight, inclined rostrad; supraoccipital crest height 27% of postethmoid skull length; width of posterior premaxillary expansion greater than 41% of length of same bone; arms of articular equal in length; gut S-folded
ventrorostrally in adults, anal and medial loops nearly touching. Further distinguished from the other species
in the genus by the abrupt, steep head profile.
Description. D. XVIII–XIX (modally XVIII),9–10; A. VII–VIII,6–7 (modally VII,7); pectoral 16–17.
First dorsal fin ray not divided. Gill rakers on lower limb of first arch 8; gill rakers distally broadened, ventrad
curved. Subsidiary pored scales on caudal fin in short rows. Scale rows on cheek 5–6; pored lateral-line scales
(not counting scales overlapping between the two segments of the lateral line) 30–32; scales from lateral line
to origin of dorsal fin 6.5–7, the dorsalmost pair reduced; scales from vent to interpelvic scale 13–17; anal
creases modally 15 (further meristic data appear in Table 3).
Largest specimen examined, 94 mm SL, maximum size 140 mm SL (Conkel 1993). Body depth 38–46%
of SL (further morphometric data appear in Table 4). Teeth not embedded; symphysial teeth equal in level to
adjacent teeth. Upper lip medially narrow; lower lip at corner of mouth tapering.
Pelvic fins inserted far behind origin of dorsal fin. Pectoral fins never reaching 1st anal-fin spine; pelvic
fins always reaching at least 5th anal-fin spine in adults. Caudal fin slightly but definitely emarginate, contra
Günther (1869), who described it as truncate (but depicted it as emarginate in his plate LXXIV, fig. 4). Scales
moderately ctenoid in young, weakly so in adults.
Gut simple in juveniles, but the basic S-shape becoming ventrorostrally folded with growth, and anal loop
displaced caudad until almost touching median loop (fig. 24i in Schmitter-Soto, in press). Gut length ca. 80%
of SL. Genital papilla rounded, semicircular, broader than long, or squarish; sunk; pigmented on margins.
A diffuse stripe from snout to eye; an indistinct vertical bar on head. Eyes blue-silver. Seven bars on sides,
diffuse, except 3rd, which constitutes a large, vertically elongated lateral blotch (this bar may be light on a dark
background instead of dark on light in some color phases); no longitudinal stripe; no blotch on caudal fin, just
base of fin darkened, same as last scales on peduncle. No dots on fins, but often hyaline areas near tip of soft
dorsal and anal fins. No spots on scales; breast dark olive. Axil of pectoral fin dusky or darkened; base of pectoral fin whitish or with same coloration as breast.
Distribution. Río Santa Clara, Costa Rica, north to lakes Nicaragua and Jiloá, Nicaragua (Fig. 27).
Remarks. The “incisor” teeth of Cr. panamensis are not a true convergence, but a different character state
(Rogers 1981; Schmitter-Soto, in press).
Discussion
The traditional “working diagnosis” of Archocentrus was based strongly on meristics, especially on the high
number of dorsal and anal fin elements, with formulae D. XVII–XX,8–11 and A. VII–XII,6–9. There have
been also morphometric attributes, albeit rather general: the pectoral fin reaching or exceeding the anal fin origin; body somewhat deep; snout short, mouth rather small, maxilla not reaching the orbital rim, neither vertically nor horizontally; teeth in the outer row subequal in size anteriorly in both jaws (Regan 1905; Kullander
1996; Greenfield & Thomerson 1997; Miller et al. 2005). No synapomorphies were known for Archocentrus,
Cryptoheros, or Hypsophrys, but some of these traditionally diagnostic characters have turned out to be synapomorphic, e.g. the number of anal-fin spines for Archocentrus; others, as expected, were convergent, e.g. the
length of the maxilla (Schmitter-Soto, in press). Still others, such as body depth, are useful for alpha-level taxonomy, but not for phylogeny reconstruction (Zelditch et al. 2005).
Allgayer (2001) had already expressed the view that Archocentrus should be restricted to Ar. centrarchus
and Ar. spinosissimus. Burgess (2000) judged that Ar. multispinosus should be added too, and Allgayer (2001)

himself included Herotilapia in his subtribe Archocentrina (= Archocentrus + Amatitlania + [Cryptoheros
without Cr. panamensis], a group for which Schmitter-Soto [in press], found no support). This opinion,
although only recently published explicitly, is a venerable one: Regan (1908) called Herotilapia “evidently
closely allied” to Archocentrus. Other authors, e.g. Bussing (1976), have considered Herotilapia “derived”
from Archocentrus.
However, most molecular phylogenetic hypotheses (Martin & Bermingham 1998; Farias et al. 2004; Hulsey et al. 2004; Concheiro Pérez et al. 2007 —all based on the cytochrome b gene) have found Herotilapia
quite unrelated from Archocentrus and allies. A possible explanation for this pattern may lie on the intrinsic
limitations of cytochrome b. As stated by Martin & Bermingham (1998), “heroine cichlids… are unfortunately refractory to phylogenetic inference using cytochrome b sequences.” Long branches are common in
“dwarf” Neotropical cichlids, such as species of Archocentrus and allies, and the cytochrome b gene presents
saturation at third-codon position (Farias et al. 2004). Other genes should provide interesting independent evidence to settle the issue.
My understanding of Cryptoheros diverges from Allgayer’s (2001), who included also what is here called
Amatitlania, and excluded Cr. panamensis. On the other hand, Kullander (2003), who did not recognize Cryptoheros, decided to call this species Archocentrus panamensis, recognizing that its affinities do not lie with
Neetroplus (nor with Hypsophrys). Am. nigrofasciata had been considered a Cryptoheros by Allgayer (2001)
and an Archocentrus by Kullander (2003).
Neetroplus has had a rather unfortunate usage history. Based on a very distinctive but overrated dental
character (like the tricuspid teeth of Herotilapia), monotypic at first, it became an artificial group with the
inclusion of several incisor-toothed cichlids, such as N. carpintis Jordan & Snyder, 1899 (= Herichthys
carpintis), N. bocourti Vaillant & Pellegrin, 1902 (= ‘Cichlasoma’ bocourti), and N. panamensis (= Cr. panamensis). Among this assemblage, H. nematopus is the only species to have incisor teeth as juvenile (Rogers
1981).
The synonymization of Neetroplus with Hypsophrys has the disadvantage of obliterating a widely used
name (Neetroplus nematopus). However, a classification should also convey information about phylogeny,
and this purpose is not served well by recognizing two monotypic sister genera instead of calling their clade
by just one generic name. An example of this stance is the synonymization of Garmanella with Jordanella
(Cyprinodontidae), in “…the interest of having generic categories define derived groups, rather than recognize individual differences…” (Parenti 1981). Moreover, the sister-group relationship of H. nicaraguensis and
H. nematopus is supported by most proposed phylogenies (e.g. Martin & Bermingham 1998; Hulsey et al.
2004; Concheiro Pérez et al. 2007).
It should be acknowledged that a classification alternative to the one here proposed, and equally congruent with the phylogeny presented by Schmitter-Soto (in press), might include all species dealt with in this
work in the genus Hypsophrys (or Amphilophus, or Parachromis, all three names having been proposed in the
same work, on the same page—Kullander & Hartel 1997). It is my opinion, notwithstanding, that the classification proposed here is more informative, and also less disruptive with recent usage. On the other hand, since
the aim of this work is to review the species formerly assigned to Archocentrus, the choice of taxa was not
ideal for such higher level decisions.
I follow the Evolutionary Species Concept (ESC). However, the ESC is not an operational concept; to be
able to recognize species under the ESC (i.e., every lineage that “maintains its identity from other such lineages and which has its own evolutionary tendencies and historical fate”: Wiley 1978), I applied here both the
“autapomorphic” and the “diagnosable” versions of the Phylogenetic Species Concept (PSC) (Mayden 1997):
every species should display at least one derived character of its own (Rosen 1979), but, if a non-homoplastic
(unique) autapomorphy is not found, then “the smallest diagnosable cluster of individual organisms within
which there is a [presumed] parental pattern of ancestry and descent” (Cracraft 1983) is to be recognized as a
species. Thus, I agree with Lucena et al. (1992), who point out that “to consider two distinguishable popula-

tions as a single species [implies] loss of information about phylogeny and biogeography.”
The phylogeny and biogeography of the species formerly assigned to Archocentrus are discussed by
Schmitter-Soto (in press).

Sven Kullander and Paul Loiselle performed very deep and constructive reviews of this work, which resulted
in a significant improvement. The paper also benefited very much from the detailed editorial labour of Carter
R. Gilbert and Larry M. Page.
This work was done while on sabbatical stay at the University of Michigan Museum of Zoology, Division
of Fishes, under a Fulbright grant (which included a travel award to present advances of this work during the
2004 ASIH meetings at Norman, Oklahoma).
I thank most warmly my hosts, Bill Fink and Jerry Smith, for giving me the opportunity to enjoy not only
their facilities at UMMZ, but also the stimulating environment they have created. An important part of that
world is the “Fish Club,” whose cichlidologist members Prosanta Chakrabarty and Ron Oldfield discussed
with me several interesting issues germane to this project.
