Abstract: The use of larval and bioacoustical characters has been essential to solve taxonomic problems of many anuran species. Herein, we describe the advertisement call and tadpoles of Pseudis fusca and P. tocantins and compare them with descriptions of all other Pseudae. The advertisement calls of Pseudis species are formed by pulsed notes. In P. cardosoi and P. minuta all pulses within a single note are concatenated, while in P. bolbodactyla, P. fusca, P. paradoxa and P. tocantins the notes are formed by sets of concatenated pulses. Moreover, the calls of P. bolbodactyla, P. fusca and P. paradoxa are indistinguishable. Tadpoles of P. fusca and P. tocantins resemble other Pseudis tadpoles described so far: their body is oval-shaped in dorsal view and triangular in lateral view and higher than wide; they possess an anteroventral oral disc with five tooth rows (two anterior and three posterior) and well developed tail musculature. The large larval size is in agreement with other species in the genus. We evaluate which characters best distinguish species within Pseudis.
