THREE NEW SPECIES OF CAECILIA LINNAEUS, 1758 (AMPHIBIA: GYMNOPHIONA: CAECILIIDAE) FROM THE COLOMBIAN ANDES, WITH COMMENTS ON THE STATUS OF C. SUBNIGRICANS DUNN, 1942
View through CrossRef
We describe three new species of the genus Caecilia from the Colombian Andes that had been previously confused with C. guntheri and C. subnigricans in the literature primarily because of overlapping annular groove counts. Caecilia decipiens sp. nov. is known only from the Pacific slopes of the Colombian Andes in Nariño, and is most similar to C. guntheri but with higher counts of primary grooves. Caecilia marielae sp. nov. is known from Risaralda and Valle del Cauca, at moderate elevations on opposite sides of the Cauca River Valley, and the species is remarkable because adult specimens retain certain characters that we associate with juvenile individuals. Caecilia peltastes sp. nov. is known from the eastern slopes of the Cordillera Central of Colombia in Antioquia y Caldas, and has straight lips that resemble Epicrionops. We comment on the taxonomic challenges posed by the genus Caecilia and emphasize the need to find new diagnostic characters.
