TL;DR: This work uses a multilocus dataset to investigate the biogeographic history and relationships among species of a small genus of salamander, Cryptotriton, restricted to the cloud forests of Nuclear Central America and suggests that isolation across relatively short geographic distances has led to range fragmentation and deep divergence between species.
TL;DR: A new species of lungless salamander (Plethodontidae) is described from the mountains of eastern Guatemala, distinguished from all other members of its genus by its yellow ventral coloration.
Abstract: A new species of lungless salamander (Plethodontidae) is described from the mountains of eastern Guatemala. The new species is distinguished from all other members of its genus by its yellow ventral coloration. It is geographically closest to its sister taxon, Cryptotriton veraepacis, from which it differs in several osteological features as well as nostril size and shape. Molecular analyses with allozyme loci and mitochondrial DNA also support its distinctiveness from C. veraepacis. This miniaturized species inhabits cloud forest habitats and has been found most commonly in bromeliads.
TL;DR: A new species of the plethodontid salamander genus Cryptotriton from Honduras is described after comparing morphological, molecular, and osteological data from the holotype to that of the other nominal forms of the genus.
Abstract: 3 Corresponding author Abstract We describe a new species of the plethodontid salamander genus Cryptotriton from Honduras after comparing morpho- logical, molecular, and osteological data from the holotype to that of the other nominal forms of the genus. The new spe- cies differs from all of the known species of Cryptotriton in at least one character from all three datasets. We also suggest placing C. wakei in the synonymy of C. nasalis after examining the morphological and osteological characters of the single known specimen of C. wakei.
