[Herpetology • 2022] Caecilia goweri • A New Species previously confused with Caecilia pachynema (Günther, 1859) (Gymnophiona: Caeciliidae) from the Cordillera Central of Colombia

Caecilia goweri
Fernandez & Lynch, 2022

Caecilia pachynema is a distinctively colored species known from western Ecuador and supposedly from a remote population in the northern Cordillera Central of Colombia. Previously it had been detected that the Colombian populations of "C. pachynema’’ were likely an undescribed species. Material gathered over the past twenty years allows us to describe this new species and restrict the known distribution of C. pachynema to Ecuador.
