From the IUCN Red List Species Account:


Range Description

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 0-450 m 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).

Population Trend


Major Threats

There are no known threats to this adaptable species.

Conservation Actions

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.

Taxonomic Notes

This is a poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.). It is unclear that all populations are conspecific.
