Vocalizações de algumas espécies do gênero Scinax (Anura, Hylidae) do sudeste do Brasil e comentários taxonômicos

Abstract

The advertisement calls of Scinax altera, S. argyreornata, S. cuspidata, S. eurydice, S. fuscomarginata, S. fuscovaria, S. hayii, S. rizibilis and S. squalirostris are described. A table with the call parameters of the species in the genus Scinax from Southeastern Brasil is presented. The specific name S. altera is confirmed but is apparently misapplied for several populations. We propose the inclusion of the species from the rizibilis group in the catharinae group, because males of S. trapicheiroi present subgular to lateralized vocal sacs, invalidating the only sinapomorphy of the rizibilis group. Characteristics of vocalization, morphology, and reproductive environment support a generic status for the species in the catharinae group (including rizibilis group).
