The salamander fauna of Colombia is very poorly known, probably because most research efforts have been devoted to anurans during the last two decades. Here, we describe two new species of the genus Bolitoglossa (Eladinea) from the eastern flank of the Eastern Colombian Andes (Cordillera Oriental), near the border with Venezuela. Bolitoglossa tamaense sp. nov. is distributed between 2000 to 2700 m.a.s.l. and Bolitoglossa leandrae sp. nov. is distributed in the low-lands at about 600 m. The new species are diagnosed by a combination of molecular (16S rRNA sequences), coloration, body size, and morphometric (number of maxillary and vomerine teeth and differences in foot webbing) characters. Both species face threats such as chytridiomycosis infections and habitat fragmentation that have already affected other sala-manders in the country. Thus, intensive field and museum work is needed to better document and perhaps protect the local salamander diversity.

A new salamander species of the genus is here described from the cloud forests of the western slopes of the Cordillera Oriental of Colombia, in the Cundinamarca department. The most salient characters of this new species are its numerous maxillary and vomerine teeth, its moderate webbing on hands and feet, its short and robust tail, and its chromatic variation. Based on molecular analyses this new species is assigned to the species group and its status established as the sister species of , with which it was previously confused.

We describe a new species of salamander of the genus Bolitoglossa from the Cordillera de Talamanca in western Panama. The new species is distinct from its congeners by its dorsal and ventral coloration, finger and toe webbing, and a comparatively high maxillary teeth count in relation to SVL. Analysis of mitochondrial DNA sequences revealed an isolated phylogenetic position of the new species which is related to the B.

We examine the phylogenetic relationships among salamanders of the genus Bolitoglossa (Eladinea) distributed in the Amazonian basin of northern Peru and southern Ecuador and assess species diversity based on morphological and phylogenetic analyses. We infer a molecular phylogeny using sequences from two mitochondrial (Cytb, 16S) and two nuclear genes (RAG-1, POMC). We find two well-supported subclades, one including [B.

We present data showing that the number of salamander species in Amazonia is vastly underestimated. We used DNA sequences of up to five genes (3 mitochondrial and 2 nuclear) of 366 specimens, 189 corresponding to 89 non-Amazonian nominal species and 177 Amazonian specimens, including types or topotypes, of eight of the nine recognized species in the region. By including representatives of all known species of Amazonian Bolitoglossa, except for one, and 73% of the currently 132 recognized species of the genus, our dataset represents the broadest sample of Bolitoglossa species, specimens, and geographic localities studied to date.

A new yellow salamander belonging to the genus Bolitoglossa, subgenus Eladinea, is described from a premontane rainforest in the vicinity of Moravia de Chirripó, on the northeastern slopes of the Cordillera de Talamanca in Costa Rica at an elevation of ca. 1300 m. This new taxon is distinguished from its congeners by its chromatic and morphological characteristics, and by differentiation in DNA sequences of the mitochondrial 16S rRNA and cytochrome b genes.
