This species is known from central and southern Chaco: northern Argentina; southeastern Bolivia; Paraguay; and Brazil (from Maranhão to São Paulo). It occurs at elevations up to 1,500m asl.
Habitat and Ecology
Burrowing form occurs on the ground near waterlogged soils, where it breeds explosively in temporary pools. It probably does not adapt well to anthropogenic disturbance.
It is locally abundant during reproductive bouts.
It is threatened in Argentina by the destruction of Chaco habitat for agriculture and wood extraction, land and water pollution caused by agrochemical runoff. In Paraguay, this species is captured (legally) for the international pet trade.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
