A new species of Pristimantis (Anura: Strabomantidae) from the Brazilian Cerrado

Abstract

A new species of Pristimantis (Anura: Strabomantidae) from the Pristimantis conspicillatus group is described from the Cerrado biome in central Brazil. Pristimantis ventrigranulosus sp. nov. is found in riparian forests associated with a particular palm tree called "babaçú" (Attalea speciosa: Aracaceae) in northwestern Goiás state of Brazil. The new species is only known from the type locality: Fazenda Macaúba (16°35'23" S; 51°47'43" W, approximately 400 m above sea level), Piranhas Municipality in the state of Goiás. The new species differs from the other species in the P. conspicillatus group mainly by having, an homogeneously granular belly, Finger I > Finger II, dorsal skin coarsely shagreen, toe and finger fringes weakly developed or absent, presence of basal webbing and tarsal fold, single nuptial pad on thumb, moderately developed and round discs on Fingers III and IV, and higher dominant frequency than other Pristimantis with similar calls (ranging 3451.8-4334.8 Hz). The new species shows an advertisement call equal in structure to the calls of P. dundeei, P. fenestratus, P. koehleri and P. vilarsi. Pristimantis dundeei is transferred to the P. conspicillatus group. Copyright © 2012 Magnolia Press.
