Studies involving bioacoustics analysis turned possible the identification of complex species groups, as well as the description and differentiation of cryptic species. In order to increase the knowledge on the species composition of amphibians in Araucaria Forests, we sampled eleven areas in the states of Parana and Santa Catarina, which significantly increased the geographic distribution range of eight amphibian species: Ischnocnema henselii, Dendropsophus anceps, a currently classified as critically endangered in Parana State, D. nandereri, Scinax granulatus, Trachycephalus dibernardoi, Pseudis cardosoi, Leptodactylus araucaria and L. nanus. Some of the new records represent corrections of previous identifications for example: Ischnocnema henselii is a cryptic species with some populations in Parana that have been previously mistaken to I. guentheri; Trachycephalus dibernardoi was mistaken for T imitatrix and Leptodactylus nanus to L. marmoratus. We also characterize and describe the calls of all these species.
