This species is known from the Serra do Mar in São Paulo and Rio de Janeiro States, Brazil. It is known from above 900m asl. It is also known from one locality in southern Rio de Janeiro State.
Habitat and Ecology
It occurs during the day on emergent rocks in shallow places in primary forest. Larvae were collected from under large rocks in a moderate-sized forest stream. The tadpoles develop in the streams. It has not been recorded outside forest habitat.
It is a common species, but very difficult to catch.
This species is restricted to primary forest and is threatened by water pollution, infrastructure development, and any kind of forest clearance.
Its range includes several protected areas. More research into the species' Extent of Occurrence is needed, in particular to determine whether or not the species occurs within the two disjunctive populations.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000km2, its range includes several protected areas, 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.
