This species is known from Serra do Mar, in São Paulo and Rio de Janeiro State, and Ilha Grande, in Rio de Janeiro State, Brazil. It has been recorded up to 900m asl.
Habitat and Ecology
This diurnal species inhabits primary and secondary forest along streams. Males call next to or over small streams on roots, rocks, and leaves. It breeds, and tadpoles develop in small-forested streams. It has not been collected outside forest habitat.
There has been an observed decline at Boracéia, but this appears to have reversed and it is now considered a very common species. It is more common in primary compared to secondary forest.
Habitat loss due to tourism disturbance and infrastructure development for human settlement is a major threat.
The cause of the observed decline is not known, although this species has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
The range of the species includes several protected areas. More research into the species' Extent of Occurrence and population status is needed, in particular to try and determine what caused the apparent decline.
