This species is known only from very low altitudes, up to 40m asl, in the States of Rio de Janeiro and São Paulo in southeastern Brazil.
Habitat and Ecology
It is a species of forest edge, and primary and secondary forest, not occurring in open areas. It breeds in temporary ponds inside a lowland forest.
It is abundant where it occurs.
The major threats are probably related to habitat loss due to clear-cutting, industry, tourism and human settlement.
It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably not much larger than 20,000 km2, it is common with a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
