This species is known from at least three municipalities in Serra do Órgãos, in Rio de Janeiro State, Brazil. It occurs at elevations of 800-1,200m asl.
Habitat and Ecology
This species lives on the floor of primary or good quality rainforest. It is a species that breeds by direct development. It has not been recorded outside forest habitat.
It is a reasonably common species.
There are no known threats to the species' habitat at present, although there was some logging, but this occurred over a hundred years ago.
The range of this species includes a couple of protected areas. Conservation and maintenance of its habitat is essential. More research into the species' Extent of Occurrence, ecological requirements and population status is needed, in particular to determine whether or not it has a wider range than currently known.
Red List Status
Least Concern (LC)
Listed as Least Concern because, although it is relatively abundant within its small range, its Extent of Occurrence is only about 5,000km2, and the extent and quality of its habitat is probably declining.
