This species is found in eastern, central, western and southern Brazil, northern Argentina (only in southern Misiones and northeastern Corrientes), northeastern Paraguay and southeastern Bolivia. It might be present in southern Tarija, Bolivia and adjacent Salta, Argentina and this requires further investigation. It is found at elevations of 0-450m asl.
Habitat and Ecology
It is a subterranean species living in forest, savannahs, shrublands and grassland. It adapts well to anthropogenic disturbance, and has even been found in urban gardens. It is oviparous with terrestrial eggs and direct development, and not dependent on water for breeding.
It is known to be common in parts of Brazil, but there are few records from Paraguay and Argentina (where it has not been collected since 1993).
There are no known threats to this adaptable species.
It occurs in several protected areas.
This is a poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.). It is unclear that all populations are conspecific.
