REDISCOVERY OF Oscaecilia ochrocephala (COPE, 1866) (AMPHIBIA: GYMNOPHIONA: CAECILIIDAE) IN COLOMBIA, WITH COMMENTS ON ITS VARIATION AND AFFINITY TO O. polyzona (FISCHER, 1880)

Abstract

We here provide the first Colombian records of Oscaecilia ochrocephala since 1942 based on material from Darién and Urabá Antioqueño. We discuss certain aspects of intraspecific variation of this species and denote its great morphological similarity to O. polyzona, which we consider as its potential sister species. Lastly we discuss the usefulness of some supposedly diagnostic characters previously found in the literature —that we consider to be of limited use— and instead propose that coloration and squamation be used in order to differentiate these two species.
