Welcome to another episode of pplpod! Today, we plunge into the fascinating world of herpetology and amphibian conservation to uncover the enigma of the Colombian backpack frog, scientifically known as "Hyla" nicefori.

Endemic to the border region between Boyacá and Casanare in Colombia, this rare amphibian is a true ghost of the forest—it is currently known from only a single type specimen collected way back in the 1940s. We explore the perplexing taxonomic mystery surrounding this species. Originally classified as a backpack frog in the genus Cryptobatrachus (family Hemiphractidae), later morphological studies revealed it actually belongs to the tree frog family, Hylidae, and it remains temporarily placed in the genus "Hyla"
