Annotated checklist of the freshwater fishes of continental and insular Honduras

Abstract

The freshwater fishes of Honduras were surveyed for a period of four years (2005-2008). Surveys were supplemented with both literature and museum collection reviews. Our results show that there are at least 172 species of fishes inhabiting Honduran mainland and insular freshwater systems, 166 native and six exotic. Primary freshwater fish diversity was low, with only eigth species (4.8%). The remaining species were either secondary freshwater (47 species, 28.3%) or peripheral (111 species, 66.9%). This checklist includes 36 new records for Honduras, and 12 range expansions. Nine species were found to be endemic; however, just two of them (Amphilophus hogaboomorum and Theraps wesseli) are already described. The depauperate primary freshwater fishes fauna of Honduras (8) is congruent with low primary freshwater fishes diversity found in the region between the Usumacinta River and the Nicaraguan great lakes. Although many previously unsampled regions of Honduras were visited as part of this project, there are a variety of remote areas that remain unstudied. While this paper contributes much to the understanding of the distribution and diversity of Honduran freshwater fishes, it is likely that much diversity there remains undocumented.

Abstract
The freshwater fishes of Honduras were surveyed for a period of four years (2005–2008). Surveys were supplemented
with both literature and museum collection reviews. Our results show that there are at least 172 species of fishes
inhabiting Honduran mainland and insular freshwater systems, 166 native and six exotic. Primary freshwater fish
diversity was low, with only eigth species (4.8%). The remaining species were either secondary freshwater (47 species,
28.3%) or peripheral (111 species, 66.9%). This checklist includes 36 new records for Honduras, and 12 range
expansions. Nine species were found to be endemic; however, just two of them (Amphilophus hogaboomorum and
Theraps wesseli
) are already described. The depauperate primary freshwater fishes fauna of Honduras (8) is congruent
with low primary freshwater fishes diversity found in the region between the Usumacinta River and the Nicaraguan great
lakes. Although many previously unsampled regions of Honduras were visited as part of this project, there are a variety
of remote areas that remain unstudied. While this paper contributes much to the understanding of the distribution and
diversity of Honduran freshwater fishes, it is likely that much diversity there remains undocumented.

Resumen
Los peces de agua dulce de Honduras fueron estudiados por un periodo de cuatro años (2005 a 2008). Los muestreos de
campo fueron complementados con revisiones tanto de colecciones de museos como de la literatura disponible. Nuestros
resultados muestran la presencia de 172 especies de peces que habitan los sistemas de aguas continentales del país y de
sus islas, de ellas 166 son nativas y seis exóticas. La diversidad de peces primarios de ambientes dulceacuícolas fue baja,
con tan solo ocho especies (4.8%) presentes. El resto fueron secundarias (47 especies, 28.3%) o periféricas (111 especies,
66.9%). Esta lista incluye 36 registros nuevos para Honduras y 12 expansiones de rango geográfico. Nueve especies
fueron reportadas como endémicas; sin embargo solamente dos (Amphilophus hogaboomorum y Theraps wesseli) son
consideradas especies válidas. La descripción de las ocho especies restantes está aún pendiente. El bajo número de
especies primarias dulceacuícolas (8) en Honduras coincide con el bajo número de especies primarias reportadas
anteriormente en la región entre el río Usumacinta y los grandes lagos de Nicaragua. Aunque muchas regiones de
Honduras que no habían sido previamente muestreadas fueron visitadas como parte de este proyecto, todavía hay áreas
remotas del país que precisan ser estudiadas. Este trabajo contribuirá extensamente al entendimiento de la distribución y
diversidad de los peces de agua dulce de Honduras; sin embargo, mucha de la diversidad ictiológica del país requiere aún
ser investigada con mayor profundidad.

FRESHWATER FISHES OF HONDURAS
Introduction
The diversity and distributional patterns of Honduran freshwater fishes are the product of recent geological
events (Myers, 1966). All primary and secondary freshwater species that inhabit Honduras are of South
American origin (Miller, 1966, Myers, 1966), moving to the region during or after the raising and closure of
the Isthmus of Panama during the Pliocene (Marshall et al., 1979, Stehli & Webb, 1985). The proposed timing
of the enclosure of the Panamanian isthmus varies from between 3.1 to 3.5 million years ago (Coates et al.,
1992, Coates & Obando, 1996) to as early as 1.8 million years ago (Keller et al., 1989). While the formation
of this land bridge is often cited as the major event structuring Honduran freshwater fish diversity, local
geologic, climatic and other factors have also certainly played a role (Savage, 1982). Unfortunately, few
attempts have been made at studying Honduran freshwater fish biodiversity on a scale adequate to assess the
role of local vs. regional processes in structuring biogeographic patterns in the country. As a result, Honduras
(Fig. 1) has long represented a large gap in biogeographical knowledge of Central America fishes (Carr and
Giovannoli, 1950, Miller, 1966, Lyons, 2005).
Accordingly, as a baseline for future biogeographical studies, we present an updated checklist of the
freshwater fishes of Honduras that has been compiled from: 1) field sampling of all major drainages, 2) data
from published literature and 3) review of museum holdings from Honduras. Checklists like this are an
important tool for researchers, governmental and non-governmental agencies with interest in documenting
and conserving biodiversity. It will serve as a foundation for future research aimed at understanding the origin
and status of Honduran fish diversity as well as effective management and conservation programs (McNeely
et al., 1990).
Review of freshwater ichthyographical research in Honduras
Most of what is known about Honduran ichthyology is based on work done at a larger regional scale.
Distributional ranges of freshwater fishes that included the territory of Honduras were mentioned in the works
of Jordan & Evermann (1896–1900), Regan (1906–1908), and Jordan et al. (1930). These publications
analyzed the freshwater ichthyofauna of Central America in general. However, sampling in Honduras was
almost non-existent at the time. In his work with cyprinodonts, Hubbs (1924, 1926 and 1931) mentioned a
number of Honduran collections containing Phallichthys amates, Belonesox belizanus, and Alfaro huberi.
Fowler (1932) reported collections in the Lancetilla and Choluteca Rivers. Rehn (1932) reported some
collections in the Honduran Mosquitia region. Strong (1934) reported a bull shark (Carcharhinus leucas) in
the Patuca River in La Mosquitia. Miller (1955) reported specimens of Profundulus guatemalensis collected
in 1934 by A. Greenberg in western Honduras. Fowler (1943) reported collections made by G. Orr in Islas de
la Bahía, and described Poecilia orri with specimens collected in the island of Bonnaca. The first detailed
sampling of rivers in the country was carried out by A. Carr in the late 1940’s. Carr focused on rivers of the
Honduran Pacific slope, culminating with an analysis of the fishes of the Choluteca River and the description
of Amphilophus hogaboomorum (Carr & Giovannoli, 1950). Carr also published a second paper on the
distribution and systematic relationships of some freshwater fishes of the Honduran and Nicaraguan
Mosquitia region (Miller & Carr, 1974).
The overall structure of Central American ichthyographical provinces was first proposed by Miller
(1966). He proposed that Honduras was part of the Chiapas-Nicaraguan Province that extends from southern
México to southern Nicaragua. Miller (1966) did not suggest separate provinces for the Honduran and
Nicaraguan Atlantic slope, arguing there was not enough information available for that part of Central
America. Ten years later, however, Bussing (1976), proposed a second additional ichthyographical province
for Honduras: the Usumacinta province on the Honduran Atlantic slope. This province extends from the
Usumacinta River in southern México to northern Nicaragua. From 1968 to 1970, Martin (1972) intensively
sampled parts of Honduras as part of an unpublished thesis. For the next two decades, there were no major
collections conducted on Honduran freshwaters fishes. In 1996, Theraps wesseli was described from

MATAMOROS ET AL. 4 · Zootaxa 2307 © 2009 Magnolia Press
individuals collected in the Bellaire River, close to the city of Jutiapa in the Department of Atlántida (Miller,
1996).
Geological history
The region of Nuclear Central America that corresponds to Honduras has a complex geological history
characterized by intensive faulting, orogeny, sea level change, sedimentation, and volcanism. The land
connection between North and South America was lost in the early Jurassic as Pangaea broke apart (Dietz &
Holden, 1970). It is widely accepted that no land connection existed between North and South America from
the early Cretaceous to the Pliocene (Holden & Dietz, 1972; Malfait & Dinkelman, 1972; Ladd, 1976;
Duellman, 1979; Savage, 1982). However, parts of Nuclear Central America, including the majority of
Honduras, may have been above water since the Cretaceous (Savage, 1982). A faunal exchange between
México and Nuclear Central America through the Isthmus of Tehuantepec happened during the Tertiary
(Olson & McGrew, 1941). This faunal exchange was facilitated by a climatic filter barrier and a probable
partial sea barrier across the Isthmus (Savage, 1982). The Miocene was characterized by intensive faulting in
the area, which produced several graben valleys, including the Honduras depression that is a corridor from the
Caribbean to the Pacific slope (Roberts & Irving, 1957). During the Miocene – Pliocene intense volcanism
occurred in the area (Roberts & Irving, 1957). Intense orogeny during late Pliocene or early Pleistocene
formed the terrace systems of interior Honduras. Much of the Caribbean lowlands emerged during the
Pleistocene as a result of extensive erosion and deposition in alluvial lowland depressions. There were also
hypothesized fluctuations in sea level and climate during the Pleistocene glaciations (Roberts & Irving, 1957).
The uplifting of the Isthmus of Panama during the mid-Pliocene created the land bridge connecting North and
South America (Beu, 2001). This facilitated a massive faunal migration from both continents, referred to as
the Great American Biotic Interchange (Marshall et al., 1979; Stehli & Webb, 1985).
Although there are no currently active volcanoes in Honduras, volcanism has shaped the physiographic
features of the country. Volcanic activity in Nuclear Central America was widespread during the Miocene and
Pliocene, which resulted in the deposition of andesitic and rhyolitic ejecta over the majority of the southern
half of Honduras (Roberts & Irving, 1957). The rough terrain in this region was largely created during the
Oligocene (the Sierras Madre in México), Miocene (highlands of Nuclear Central America) and Pliocene
(highlands of Lower Central America including the Comayagua Graben) (Roberts & Irving, 1957;
Maldonado-Koerdell, 1964; Savage, 1982). The Gulf of Fonseca was formed by downfaulting at the
Comayagua Graben and the Nicaraguan Graben (West, 1964). Finally, Islas de la Bahía on the Honduran
Caribbean coast (Fig. 1) appear to be a northward extension of the Sierra de Omoa and were apparently
connected to the mainland throughout most of the middle and late Tertiary (Vinson & Brineman, 1963).
Physiography
A physiographical region is defined as a geographic area with similar geologic, topographic, and edaphic
features (West, 1964). Subdivisions of these physiographic regions are called sub-regions, in which there is a
general uniformity of surface features (Martin, 1972). There are three major physiographic regions proposed
for Honduras (Bengston, 1926; Carr, 1950; Martin, 1972): the Pacific Lowlands, the Caribbean Lowlands, and
the Interior Serranía Region. The Pacific Lowlands region does not contain any sub-regions, but includes the
river basins that drain into the Gulf of Fonseca (Bengston, 1926; Carr 1950). This includes the Goascorán,
Nacaome, Choluteca, and Negro rivers (Fig. 2). The Caribbean Lowlands extend from the delta of the
Motagua River in western Honduras to the Coco River bordering Nicaragua. The Caribbean lowlands are
divided into five sub-regions (Bengston 1926; Carr 1950); the Motagua River Delta, the Ulúa-Chamelecón
River Valley, the Nombre de Dios Plain, the Aguán-Negro River Plain, and the Mosquitia Coast (Fig. 2). The
Interior Serrania Region is formed by the Northern Cordillera and the Southern Cordillera sub-regions.
Detailed description of Honduran physiographic regions and sub-regions are found in Bengston (1926), Carr
(1950), Martin (1972), Wilson & Meyer (1985) and McCraine & Wilson (1985).

Field sampling at 278 localities in Honduras was performed in July 2005, November 2005, May–July
2006, May–August 2007, January–March 2008, and June–August 2008 (Fig. 1). Sampling gear included
seines (various sizes) with a mesh of 3.1 mm, cast nets, spear fishing, and backpack electrofishers. Captured
fishes were fixed in 10% buffered formalin solution before being rinsed in water and preserved in 75%
ethanol. Specimens were deposited at USM. To complement distribution and diversity data collected in our
field surveys, we reviewed both the scientific and “grey” literature. We also queried the inter-institutional
database NEODAT (http://www.neodat.org) and the online data bases of FLMNH, FMNH, GCRL, LACM,
and UMMZ. The first author personally reviewed the Honduran freshwater fish holdings at the collections of
the following museums: FLMNH, FMNH, GCRL, and parts of the Honduran holdings at UMMZ.
The annotated checklist is arranged by order and family following Eschmeyer & Fong (2008). Genera and
species within a family are arranged in alphabetical order. The family tolerance to salinity is listed according

MATAMOROS ET AL. 6 · Zootaxa 2307 © 2009 Magnolia Press
to the classification by Myers (1949). Species valid name, authority, and year of description follow
Eschmeyer & Fricke (2009), with the exception of Rhamdia quelen from which we follow Perdices et al.
(2002) in considering all Honduran R. quelen as belonging to the species R. guatemalensis. Honduran taxa
included in the genus Cichlasoma is referred to here as ‘Cichlasoma’ following Kullander (2003).
After the authority name, the common English name was provided followed by the common Spanish
name. After the common name, we specify its origin as native, endemic or exotic. The exotic species included
in the checklist are only those for which there is evidence of reproductive populations in Honduras.
The distribution of each species is given in two ways and is based on our own collections, literature
reviews, online databases and museum specimens. First, we list the Honduran departments (alphabetical
order) for which there are records for the species. Second, we list the major river drainage basins (Atlantic
slope before Pacific slope drainages, all listed in west to east order) for which there are records for the species.
A considerable number of records on the checklist represent expansions of the known range or new
reports of the species for Honduras. For range expansions and new country records (or both), we list the
museum specimens that are associated with the individual specimens of interest. In the event that the museum
specimen is not available, the field collection number is given. Finally, we considered a species new to
Honduras as one that is not listed for Honduras either in FishBase (Froese & Pauly, 2009) or Reis et al.
(2003).

Remarks: Bussing (2002) describes the distributional range for R. bouchellei as across the Atlantic slope
of Central America from the Patuca River in Honduras to the Matina River in Costa Rica. Martin (1972)
reported R. bouchellei (field numbers MMH 1969-14, MMH 1969-19, material deposited at LACM) in the
Sico-Tinto o Negro River, which is located west of the Patuca River. We consider the distributional range of R.
bouchellei to extend from the Sico-Tinto o Negro River in Honduras to the Matina River in Costa Rica, in the
Atlantic slope of Central America.
SILURIFORMES
Ariidae. Peripheral.
Cathorops higuchii Marceniuk & Betancur-R., 2008. Higuchi’s Sea Catfish, bagre de Higuchi. Native.
Department: Gracias a Dios. Drainage: Atlantic slope: Coco.
Remarks: Details about the distribution of this species in Honduras and Mesoamerica are given by
Marceniuk & Betancur-R. (2008).
Cathorops melanopus (Günther, 1864). Dark sea catfish, bagre prieto. Native.
Departments: Cortés and Santa Bárbara. Drainages: Atlantic slope: Motagua and Ulúa.
Remarks: C. melanopus was thought to be endemic to the Motagua river basin in Guatemala and possibly
occurring in Honduras (Marceniuk & Betancur-R., 2008). Vouchers LACM 32355-1 collected in the Río Ulúa
in the department of Santa Bárbara, and LACM 32405-1 collected in the Río Blanco (tributary of the Ulúa
River) represent the first records of C. melanopus in Honduras as well as a significant range extension.
Furthermore, Vaux (1985) collected C. melanopus at the Yure River (at the confluence with the Quebrada de
Chamo), which is a tributary of the Humuya River, Río Ulúa system.
Cathorops sp. Raredon’s sea catfish, bagre de Raredon. Native.

MATAMOROS ET AL. 10 · Zootaxa 2307 © 2009 Magnolia Press
Remarks: The distributional range of the Raredon’s sea catfish as reported by Marceniuk et al. (in press),
extends from Sinaloa México to the department of La Libertad to La Unión in El Salvador. In the description
of the species, Marceniuk et al. (in press) included material collected in La Unión Bay. La Unión Bay is a
small body of water located in the Gulf of Fonseca bordering Honduras and El Salvador. Based on the
geographical location of the La Unión Bay, it is most likely that the Raredon’s sea catfish also occurs in
Honduras (R. Betancur-R., pers. comm.).
Cathorops steindachneri (Gilbert & Starks, 1904). Steindachner’s sea catfish, bagre de Steindachner. Native.
Remarks: The distributional range of C. steindachneri extends from El Salvador to Panama (Marceniuk
et al., in press). This species has been reported from the Gulf of Fonseca in El Salvador, but is also potentially
present on the Honduran side of the Gulf of Fonseca (R. Betancur-R., pers. comm.; Marceniuk et al., in press),
since the Gulf of Fonseca is a shared body of water between these two countries.
Cathorops taylori (Hildebrand, 1925). Taylor’s sea catfish, bagre de Taylor. Native.
Remarks: While no specimens of this species have been collected in Honduras, its occurrence in the
country is very likely (R. Betancur-R., pers. comm.). Marceniuk et al. (in press) listed specimens collected in
La Unión Bay, which is a small shared body of water at the Honduras – El Salvador border.
Sciades assimilis (Günther, 1864). Maya sea catfish, bagre maya. Native.
Department: Cortés. Drainage: Atlantic slope: Chamelecón.
Sciades guatemalensis (Günther, 1864). Widehead sea catfish, bagre guatemalense. Native.
Departments: Choluteca and Valle. Drainages: Pacific slope: Nacaome and Choluteca.
Sciades seemanni (Günther, 1864). Tete sea catfish, bagre tete. Native.
Departments: Choluteca and Valle. Drainages: Pacific slope: Lempa, Goascorán, Nacaome and Negro.
Ictaluridae. Primary.
Ictalurus punctatus (Rafinesque, 1818). Channel catfish, bagre de canal. Exotic.
Departments: Comayagua, Cortés and Santa Bárbara. Drainages: Atlantic slope: Chamelecón and Ulúa.
Remarks: I. punctatus was introduced in Honduras in the early 1960s for aquaculture purposes by
technicians of the United Fruit Company. During Hurricane Fifi in 1975, many fish escaped into the Ulúa and
Chamelecón Rivers. In the environmental impact study prior to building the El Cajón reservoir, Vaux (1985)
reported I. punctatus. There is also evidence of at least one fish farmer in Comayagua that has been capable of

Remarks: Silfvergrip’s (1996) revision of the genus Rhamdia synonymized R. guatemalensis with R.
quelen. Perdices et al. (2002) analyzed the evolutionary history of the genus in Central America and
concluded that South American R. quelen are evolutionarily distinct from R. guatemalensis from Central
America. Here we treat R. guatemalensis as a distinct species.

Remarks: The distribution of P. gillii presented here is based on Bussing (2002).
Poecilia marcellinoi Poeser, 1995. Marcellino’s Molly, olomina de Marcellino. Native.
Departments: Choluteca, Comayagua, Copán, Cortés, El Paraíso and Santa Bárbara. Drainages: Atlantic
slope: Motagua and Ulúa. Pacific slope: Lempa and Choluteca.
Remarks: Miller (1907) found P. marcellinoi in the Motagua River basin. In redescribing the species,
Poeser (1995) listed a number of localities from the Lempa River in El Salvador. Because Salvadorian
drainages all have headwaters in Honduras, it would not be surprising to find this species on the Honduran
side of the Lempa River. Furthermore, Villa (1982) listed a Poecilia sp. from the Ulúa River in Honduras.
This species is considered by Poeser (unpubl. data) to be P. marcellinoi. Finally, we collected P. marcellinoi in
the Choluteca River drainage, meaning the Honduran distribution of P. marcellinoi may be broader than
presented here.

Remarks: Micropterus salmoides was introduced into Lake of Yojoá as a sport fish (Ostmark, 1964;
Cruz, 1985). The literature suggests an introduction in the early 1950s (Ostmark, 1964; Cruz, 1985).
However, an earlier arrival in Honduras is possible. Cruz (1985) studied the biology of M. salmoides in the
Lake of Yojoá and provided a synopsis of the introduction. Vaux (1985) collected M. salmoides in the Laguna
de Yure which is adjacent to the Lake of Yojoá. We have not collected M. salmoides outside of the previously

Cichlidae. Secondary.
Amatitlania nigrofasciata (Günther, 1867). Convict cichlid, conguito convicto. Native.
Departments: Choluteca, El Paraíso, Francisco Morazán, Gracias a Dios, Intibucá, Olancho, Valle and
Yoro. Drainages: Atlantic slope: Lislis, Aguán, Sico-Tinto, Patuca, Warunta and Coco. Pacific slope: Lempa,
Goascorán, Nacaome, Choluteca and Negro.
Amatitlania siquia Schmitter-Soto, 2007. Siquia cichlid, conguito del Siquia. Native.
Departments: El Paraíso, Francisco Morazán, and Gracias a Dios. Drainages: Atlantic slope: Coco.
Pacific slope: Choluteca.
Remarks: The locality from the Yeguare River listed in Schmitter-Soto (2007) as an Atlantic locality is
an error. The Yeguare River is a tributary of the Choluteca River which drains into the Gulf of Fonseca. Thus,
in Honduras, A. siquia is found in both the Pacific and Atlantic slopes.
Amphilophus alfari (Meek, 1907). Pastel Cichlid, mojarra pastel. Native.
Departments: Gracias a Dios and Olancho. Drainages: Atlantic slope: Plátano, Patuca, Warunta and
Coco.
Amphilophus hogaboomorum (Carr & Giovannoli, 1950). Cholutecan Mojarra, Mojarra de Choluteca.
Endemic.
Departments: Choluteca. Drainages: Pacific slope: Choluteca and Negro.
Remarks: The distribution of this fish was limited to the lower reaches of the Choluteca River. We
collected this species in the Negro River (USM field number WAM08-18) near the community El Ojo de
Agua, and in a second locality in the lower reaches of the Choluteca River (USM 31935) near the community
of El Mal Paso on the road to Orocuina. These two reports represent a range extension for A. hogaboomorum.
Amphilophus longimanus (Günther, 1867). Redbreast cichlid, mojarra pecho rojo. Native.
Departments: Choluteca, El Paraíso, Francisco Morazán, Gracias a Dios, Olancho, Valle and Yoro,
Drainages: Atlantic slope: Aguán, Sico-Tinto, Plátano, Patuca, Warunta and Coco. Pacific slope: Nacaome,
Choluteca and Negro.
Amphilophus robertsoni (Regan, 1905). Honduran cichlid, mojarra hondureña. Native.
Departments: Atlántida, Colón, Cortés, Gracias a Dios, Santa Bárbara and Yoro. Drainages: Atlantic
slope: Motagua, Chamelecón, Ulúa, Leán, Cangrejal, Lislis, Aguán, Sico-Tinto, Plátano and Patuca.
Remarks: Greenfield & Thomerson (1997) limited the southernmost range of this species to the
department of Atlántida. However, Miller et al. (2005) listed UMMZ 188235 as A. robertsoni collected in the
upper Patuca River in eastern Honduras.
Archocentrus centrarchus (Gill, 1877). Flier cichlid, mojarrita rayada. Native.
Department: Choluteca. Drainages: Pacific slope: Choluteca and Negro.
Remarks: Schmitter-Soto (2007) states that A. centrarchus is found in drainages of the Gulf of Fonseca.
A. centrarchus has been reported in Honduras only in two Gulf of Fonseca drainages, the Negro and
Choluteca Rivers (Cruz & Espinal, 1989), but there is no evidence of its occurrence in the Nacaome and
Goascorán Rivers.
Archocentrus multispinosus (Günther, 1867). Rainbow cichlid, mojarrita arcoiris. Native.
Departments: Choluteca and Gracias a Dios. Drainages: Atlantic slope: Patuca, Warunta and Coco.

Remarks: Schmitter-Soto (2007) found the northernmost limit of this species on the Pacific slope of
Central America in the Guasaule River in Nicaragua. We collected this species in the Negro River (USM field
number WAM08-20) and the Choluteca River (USM 31494). In addition, Cruz and Espinal (1989) also
reported A. multispinosus in the Negro and Choluteca Rivers.
‘Cichlasoma’ trimaculatum (Günther, 1867). Threespot cichlid, mojarra prieta. Native.
Department: Valle. Drainages: Pacific slope: Lempa and Goascorán.
‘Cichlasoma’ urophthalmus (Günther, 1862). Mayan cichlid, mojarra maya. Native.

Yoro. Drainages: Atlantic slope: Motagua, Chamelecón, Ulúa, Leán, Cangrejal, Lislis, Aguán, Sico-Tinto and
Patuca. Pacific slope: Choluteca.
Remarks: Schmitter-Soto (2007) restricts the distribution of this species to the Atlantic slope drainages of
Honduras and Guatemala with its easternmost boundary at the Aguán River in Honduras. We collected C.
cutteri in the Honduran Pacific slope (USM field number WAM08-43; Choluteca River basin, Valle de
Zamorano). This collection represents a range extension for C. cutteri.
Hypsophrys nicaraguensis (Günther, 1864). Butterfly cichlid, moga amarilla. Native.
Department: Gracias a Dios. Drainage: Atlantic slope: Coco.
Remarks: The northern most reported boundary of H. nicaraguensis is a locality in the Nicaraguan side
of the Coco River bordering Honduras (Schmitter-Soto, 2007). During this project H. nicaraguensis was
colleted in the Rus Rus River on the Honduran side of the Coco River (USM field numbers WAM08-05 and
WAM08-08). These records represent a range expansion for the species and a new species report for
Honduras.
Oreochromis mossambicus (Peters, 1852). Mozambique tilapia, tilapia mozambiqueña. Exotic.
Departments: Intibucá, La Paz. Drainage: Pacific slope: Lempa.

Results and discussion
The native freshwater fish fauna of Honduras is composed of 166 species in 96 genera, 41 families, and 18
orders (Appendix). In addition to the native species, six exotic species were found in the country. The most
speciose families are Cichlidae (22 species), Poeciliidae (17 species), and Gobiidae (15 species). Based on
published salinity tolerances (Myers, 1949), just 4.8% (8 species) of the total freshwater native fish species
are primary or obligate freshwater. These eight species are represented in just three families: Characidae (A.
aeneus, B. guatemalensis, H. tortuguerae and R. bouchellei), Heptapteridae (R. guatemalensis and R.
laticauda.) and Gymnotidae (G. cylindricus and G. maculosus). The secondary and peripheral freshwater
species represent 28.3% and 66.9% of the freshwater fish fauna, respectively. The paucity of Honduran
primary or obligate freshwater fishes found in this study is not surprising, given Myers’ (1966) suggested
history and composition of the Central American freshwater fish fauna.
A total of 36 species were new records for Honduras, and there were 12 species found to have expanded
ranges. Nine species appear to be endemic to Honduras, of which only two have been formally described: the
cichlids A. hogaboomorun and T. wesseli. Of the remaining six endemic species, descriptions of Profundulus
sp.1 and Poecilia sp.1 are either in review or in preparation and four other species listed herein are awaiting
description.

With the exception of El Salvador, most Central American countries now have fairly recent formal species
lists. These lists include: México (Miller et al., 2005), Belize (Greenfield & Thomerson, 1997), Guatemala
(Kihn-Pineda et al. 2006), Nicaragua (Villa, 1982), Costa Rica (Bussing, 2002), Panama (Loftin, 1965) and
Honduras (this publication). The only formal list for El Salvador dates back to 1925 (Hildebrand, 1925). In
addition, large areas of some countries, such as the Mosquitia region of both Honduras and Nicaragua, are
logistically difficult to sample and require more exploratory work which would likely yield additional
diversity. Compared to other Central American countries, Honduras appears to have the smallest primary or
obligate freshwater fish diversity (8 species). Given the geologic history and drainage patterns for the region,
it is likely that El Salvador is similarly depauperate in these groups.
The primary freshwater fish composition of Nicaragua is very similar to that of Honduras and differs only
for a few species in the family Characidae which are absent in Honduras. A number of species in the families
Heptapteridae (See Villa, 1982; Bussing, 2002) and Gymnotidae are found in both countries (see Albert &
Miller, 1995, Albert et al., 1999, Albert, 2001). Moving north of Honduras, major differences in fish
assemblages appear to start in northern Guatemala near the Mexican border (see Kihn-Pineda et al. 2006;
Valdez-Moreno et al., 2005), Belize (see Greenfield and Thomerson 1997) and Southern México (see Miller
et al., 2005, Lozano-Vilano et al., 2007 and González-Díaz et al., 2008). A number of species of primary or
obligate North American freshwater fishes families Ictaluridae and Catostomidae extend their ranges this far
south. However, the central and southern portions of Guatemala bordering Honduras appears to have primary
or obligate freshwater species assemblages very similar to that of Honduras.
Martin (1972) was struck by the apparent lack of endemism seen in Honduras. His surveys found just one
endemic freshwater fish for the country (A. hogaboomorum). It was not until 1996 that T. wesseli was
described (Miller, 1996). Our samples appear to contain a number of putatively undescribed species
(Appendix), which are endemic to Honduras. We suspect that the perceived lack of endemism in Honduras is
due to insufficient ichthyological research in the country. Further, of all putative new species reported here,
none are primary freshwater fishes, and most are in the families Poeciliidae, Profundulidae, and Gobiidae.
As with most aspects of Honduran freshwater fish biogeography, the ecology and conservation impacts of
exotic species are largely unknown. Most freshwater exotics were introduced for aquaculture purposes, with
the notable exception of largemouth bass (M. salmoides) introduced in the early 1950’s as a sport fish (Cruz,
1985). All indications are that M. salmoides has not spread beyond the original site of introduction. Of the
remaining five exotic species, the Nile and Mozambique tilapias (O. niloticus and O. mossambicus,
respectively) have spread the most widely and potentially pose the greatest threat to native species. Three
other species have been introduced to Honduras since the early 1980’s for the purpose of aquaculture
(Colossoma macropomum, Oncorhynchus mykiss and Oreochromis urolepis hornorum; D. Meyer, pers.
comm.), but there is no evidence that these species are reproducing in the wild.
One of the main goals of this project was to compile data from as much of Honduras as possible. Our
broad approach was intended to be thorough, including museum material, published literature, and extensive
direct sampling throughout the country. While our four-year sampling effort increased the number of
Honduran freshwater fish on this checklist, substantial areas of the country remain unexplored. In particular,
remote areas of the departments of Gracias a Dios and Olancho in the east, and Lempira, Intibucá and
Ocotepeque in the west require further sampling (Fig. 1). Given these gaps, this study is not the definitive
work on Honduran freshwater fishes, but it is our hope that the data presented here will serve as the
foundation for further study and conservation action.
