Here we review the systematics of the threadsnakes of the Epictia goudotii Species complex in Middle and northern South America using external morphology and molecular data. Two species, Epictia goudotii and E. magnamaculata , are currently recognized from that region, but we provide evidence for recognizing, as species, three other nominal forms u...
Article
An updated checklist of the amphibians and reptiles of Honduras is provided. The list includes three amphibian species (Ptychohyla euthysanota, Bolitoglossa odonnelli, Oedipina chortiorum) and two reptile species (Laemanctus waltersi [elevated from subspecies status], Epictia phenops) not included in the most recent checklist of the amphibians and...
Article
In this review, we provide thorough descriptions of the 39 named species of the family Dactyloidae (commonly referred to as anoles) we recognize as occurring in Honduras. We follow two recent phylogenetic analyses suggesting eight genera of anoles are recognizable, two of which occur in Honduras (Anolis and Norops). Each species account contains a...

We describe a new species of the plethodontid salamander genus Cryptotriton from Honduras after comparing morphological, molecular, and osteological data from the holotype to that of the other nominal forms of the genus. The new species differs from all of the known species of Cryptotriton in at least one character from all three datasets. We also...
Article
We provide the results of a morphological and molecular study on the Honduran Bay Island and mainland populations of the Cnemidophorus lemniscatus complex for which we resurrect C. ruatanus comb. nov. as a full species. Morphological comparison of the Honduran populations to Cnemidophorus populations from Panama led to the conclusion that the Panam...
Article
Morphological and molecular analyses of the Phyllodactylus populations on the Honduran Bay Islands of Guanaja, Roatán, and Utila demonstrate that the Guanaja population is best treated as a species distinct from the two other island populations. Thus, P. palmeus is restricted in distribution to Roatán and Utila islands and the Cayos Cochinos and a...
Article
Recently, we described two new species of geckos of the genus Sphaerodactylus from the Bay Islands of Honduras. After further collections, and morphological and molecular analyses, we describe two additional species here. One of the new species belongs to the S. millepunctatus species group, which is centered in Middle America. The other new specie...
Article
We report the discovery of a population of Trachemys grayi emolli in southern Honduras. Verification of the species was based on both morphological and molecular data (ND4, COI, ctyb). We discuss problems that arise from the use of sequences from non-vouchered pet trade and turtle farm samples for inferring phylogenetic relationships and confirming...
Article
Full-text available
Effective and targeted conservation action requires detailed information about species, their distribution, systematics and ecology as well as the distribution of threat processes which affect them. Knowledge of reptilian diversity remains surprisingly disparate, and innovative means of gaining rapid insight into the status of reptiles are needed i...
Article
We performed a morphological and molecular study on various Honduran populations of the Sphaerodactylus millepunctatus complex. As a result, we resurrect S. continentalis from the synonymy of S. millepunctatus and describe two new species from the Islas de la Bahía. Our results also suggest the possibility that other cryptic species might occur in...
Article
Full-text available
We describe a new species of Oedipina (subgenus Oedopinola) from Parque Nacional Pico Bonito in the central portion of the Cordillera Nombre de Dios in north-central Honduras. The new species was previously assigned to O. gephyra, but a combination of molecular analyses and its differences in foot morphology diagnose it from O. gephyra.
Article
Eleutherodactylus operosus is placed in the synonymy of Eleutherodactylus cerasinus, based on the collection of new specimens from eastern Honduras.

The conservation status of the members of the Honduran herpetofauna is discussed. Based on current and projected future human population growth, it is posited that the entire herpetofauna is endangered. The known herpetofauna of Honduras currently consists of 334 species, including 117 amphibians and 217 reptiles (including six marine reptiles, whi...
Article
The cloud forest amphibians and reptiles constitute the most important herpetofaunal segment in Honduras, due to the prevalence of endemic and Nuclear Middle American-restricted species. This segment, however, is subject to severe environmental threats due to the actions of humans. Of the 334 species of amphibians and reptiles currently known from...
Article
Population declines of several members of the Honduran herpetofauna have occured despite a reasonably robust system of biotic reserves. A procedure was developed to identify "indicator species" whose biological features can be used to establish a gauge of environmental stability for most ecophysiographic areas in Honduras. A total of 103 species wi...
Article
A new species of anole of the genus Norops is described from Departamento de Yoro in northwestern Honduras. The new species appears to be most closely related to members of the N. cupreus species group and is most easily distinguished from those species by male dewlap color and in having a single anterior nasal scale. Una nueva especie de anolito d...
Article
The recent collection of 12 specimens of Typhlops from northwestern Honduras demonstrates that Typhlops stadelmani is a valid species of wormsnake. Thus, Typhlops stadelmani is removed from the synonymy of Typhlops tenuis. A taxonomic synopsis of the newly defined T. stadelmani is provided.
Article
A new species of the Bufo valliceps group is described from the Caribbean versant of north-central Honduras. The new species can be distinguished from the other members of the group by the following combination of characters: supraorbital and parietal crests strongly elevated, higher than postorbital crest at confluence of these three crests; parie...
Article
Examination of the holotype of Rhadinaea pinicola Mertens revealed no coloration or scutellation characters that would distinguish it from R. kinkelini Boettger. We conclude that the nominal taxon R. pinicola Mertens is a junior synonym of R. kinkelini Boettger.
Article
Two new species of anoles of the Norops crassulus group are described from Honduras. Both are distinguished from all other species of the genus Norops by unique characteristics of scale morphology and meristics, limb proportions, and male dewlap coloration.
Article
A new species of Plectrohyla, previously identified as P. teuchestes, is described from Parque Nacional El Cusuco in northwestern Honduras. Adults of the new species differ from those of P. teuchestes in snout shape, size, and several features of color in life. Several differences in tadpole morphology also exist between the two species.

The Central American nation of Honduras currently has an extensive system of national parks and other protected areas. Most are located in mountainous areas, but the largest ones are found in lowland areas (Wilson et al., in press). Nonetheless, most of these protected areas receive scant, if any, real protection. Very few have research and managem...
Article
Two new species of Hyalinobatrachium are described from eastern Honduras. The first is distinguished from all other Mexican and Central American species of the genus, except for H. chirripoi, by having extensive webbing between fingers II-III and a clear parietal pericardium. This taxon is most easily distinguished from H. chirripoi by having smoot...
Article
A new species of salamander of the genus Bolitoglossa is described from a cloud forest locality in northwestern Honduras. Its combination of strongly sexually dimorphic color patterns, extensively webbed feet that lack subdigital pads, and well-developed terminal phalangeal elements with most terminal phalanges expanded distally easily distinguish...
