ON THE IDENTITY OF CYCLORAMPHUS JORDANENSIS HEYER, 1983 (ANURA: CYCLORAMPHIDAE)

Abstract

Cycloramphus jordanensis was described based on a single preserved specimen from Campos do Jordao (22 degrees 44` S ,45 degrees 35` W), State of Sao Paulo, Brazil. While examining the holotype; we noticed the presence of toe and tarsal fringes. Because these characters are absent in Cycloramphus, we suspected that the species was mistakenly placed in the genus. X-ray images of the holotype revealed T-shaped terminal phalanges and fang-like teeth. Together with the presence of toe and tarsal fringes, these characters squarely place the specimen in the genus Megaelasia. Considering the striking niche differences between Cycloramphus and Megaclosia, we expect the new combination will facilitate location of new individuals of this rare frog.
