This species occurs in the southern and central part of the State of São Paulo, in southeastern Brazil at around 800m asl. Its altitudinal range is presumably wider than this.
Habitat and Ecology
It lives on the ground near streams, on in the water, in primary and secondary forest. It is a diurnal species. It breeds in streams, and the eggs are placed in crevices under rocks or stones.
It is very common in its relatively restricted range.
The main threats are loss of habitat as a result of clear-cutting, human settlement and tourism. In addition, the species has recently tested positive for the chytrid fungus Batrachochytrium dendrobatidis (Carnaval et al., 2006).
It occurs in at least three protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably not much greater than 20,000 km2, it is common and reasonably adaptable with a presumed large population, and it is unlikely to be declining to qualify for listing in a more threatened category.
