This species is known only from the Serra do Mar in the states of Paraná and Santa Catarina in southern Brazil at 800-1,000m asl.
Habitat and Ecology
It is a terrestrial species that lives in secondary and old growth forest. It reproduces in ephemeral pools. It does not occur in open areas outside forest.
It occurs in scattered localities, but it is often common where is found. Its population is stable in suitable habitats.
The main threats are deforestation, expanding cattle ranching, and expanding pine plantations.
Although it is not currently protected in any reserve, its range still includes much intact forest.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
