A new species of Allobates (Anura, Dendrobatidae) from the western flank of the Serrania de Perij a, Colombia

摘要

A new species of nurse frog is described from the Serrania de Perij a, Colombia. The new species is the fourth trans-Andean species in the genus Allobates. The new species is very similar to Allobates wayuu and also resembles A. melanolaemus,A. mcdiarmidi, A. niputidea, A. spumaponens and A. trilineatus, but differs in the type of posterior joining of the dorsolateral stripe, pattern of coloration on the gular-chest region in males, ventral coloration in females, and by the pattern of the oblique lateral stripe; moreover, their similar are geographically isolate. Although Allobates is the second largest genus of dendrobatids (45 species), in Colombia, it has a diversity of thirteen species (including the new one described herein), nine m-Andean andfour trans-Andean. It is probable that the diversity in Colombia is underestimated.
