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.
哥伦比亚的蝾螈动物群鲜为人知，这可能是因为在过去二十年里，大多数研究工作都集中在蛙类身上。在此，我们描述了来自哥伦比亚东部安第斯山脉（东方山脉）东坡、靠近委内瑞拉边境的Bolitoglossa（Eladinea）属的两个新物种。新物种Bolitoglossa tamaense分布于海拔2000至2700米之间，Bolitoglossa leandrae分布于约600米的低地。这些新物种通过分子特征（16S rRNA序列）、体色、体型以及形态测量特征（上颌齿和犁骨齿数量以及蹼足差异）的组合来鉴别。这两个物种都面临着诸如壶菌病感染和栖息地破碎化等威胁，这些威胁已经影响到了该国的其他蝾螈。因此，需要开展深入的野外和博物馆工作，以更好地记录并可能保护当地蝾螈的多样性。
