This species occurs widely in central and southeastern Brazil, the eastern Santa Cruz lowlands of Bolivia, eastern Paraguay and the alto-Paraguay area. In spite of assertions by Cei (1980) and Asociación Herpetológica Argentina (2000), the species probably does not occur in Argentina. Its altitudinal range is from 0-1,500m asl.
Habitat and Ecology
It is a typical fossorial and seasonal frog, well adapted to a semi-arid continental climate. It inhabits savannah and grassland habitats in the Cerrado biome, and occurs on the ground near standing and temporary waterbodies, such as ponds and swamps, where it also breeds. It does not adapt well to anthropogenic disturbance.
It is a common species.
The spread of intensive agriculture in the Cerrado biome is presumably affecting local populations of this species.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
