A new species of Scinax Wagler (Anura: Hylidae) from Paraná, Southern Brazil

Abstract

In this article, we describe a new species of Scinax from the state of Paraná, southern Brazil, based on the external mor-phology of adults and their advertisement calls. The new species is diagnosed by the size of its males (SVL 27.8-31.6 mm); the snout subovoid in the dorsal view and slightly acuminate in profile; the vocal sac subgular and ventrally not reaching the pectoral region; and the advertisement call composed of a single pulsed note with 7-13 pulses, and a duration of 0.16-0.25s. This new species occurs in natural highland grassland formations, in the threatened ecosystem of the At-lantic Forest in the state of Paraná, southern Brazil.
