Vocalizações de Scinax perpusillus (A. Lutz & B. Lutz, 1939) e S. arduous Peixoto, 2002 (Anura, Hylidae), com comentários taxonômicos

Abstract

Herein, the advertisement and territorial calls recorded from topotypes of Scinax arduous Peixoto, 2002 and S. perpusillus (A. Lutz & B. Lutz, 1939) are described. These two species belong to the Scinax perpusillus species group and show acoustic parameters of territorial calls similar to the catharinae species group, suggesting that they are phylogenetically related. The acoustic parameters of advertisement calls of S. arduous and S. perpusillus suggest a monophyletic origin for the Scinax perpusillus species group.
