Hylid or microhylid? No evidence for the occurrence of Trachycephalus mesophaeus (Anura, Hylidae) in Argentina

Abstract

A recent publication reported the Atlantic Forest endemic hylid Trachycephalus mesophaeus for the Chacoan ecoregion in Argentina. In this paper, we analyzed the voucher specimen and showed that it is a misidentified specimen of the Asiatic microhylid Kaloula pulchra, a species commonly commercialized in the pet trade worldwide. Therefore, there is no evidence for the occurrence of T. mesophaeus in Argentina.
