Advertisement call of Zachaenus carvalhoi Izecksohn, 1982 (Anura: Cycloramphidae) from southeastern Brazil

摘要

Anuran advertisement calls are species-specific and widely used as a taxonomic tool (e.g., Heyer et al. 1996; Pombal et al. 2011; Taucce et al. 2012). Nevertheless, in many taxa the vocalizations have not yet been formally described, as in Zachaenus Cope, 1866 (Anura; Cycloramphidae). This genus is endemic to the Brazilian Atlantic Rainforest (Verdade et al. 2009) and currently comprises two species: Zachaenus parvulus (Girard 1853) and Z. carvalhoi Izecksohn, 1982. Herein we describe the advertisement call of the data deficient (Peixoto & Silvano 2004) Z carvalhoi, providing for the first time information on the vocalization of the genus.
