This species is known from central, southeastern and northeastern Brazil, eastern Bolivia and southern Paraguay. It occurs up to 2,000m asl.
Habitat and Ecology
It occurs in open areas and rocky outcrops, in rock or termite cavities and the tadpoles develop in lentic habitats (quiet side pools of the stream). It does not seem to adapt well to anthropogenic disturbance.
It is only common in ideal habitat situations.
There is little information, but overgrazing, agricultural intensification, and fire might impact local populations.
Its range includes several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its large distribution and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
