This species is known from parts of the Serra do Mar (including the Serra dos Órgãos, the Serra da Mantiqueira, and the Serra da Bocaina), in Brazil. It has been recorded between 100-1,100m asl.
Habitat and Ecology
It is restricted to forest, where it lives on the ground and is usually not associated with water. Its breeding habits are not known, though reproduction is presumably by terrestrial larval development. Advertisement and territorial calls are reported in Brasileiro et al. (2007).
It might be common but it is a very cryptic species, so it is very difficult to study.
Habitat loss due to infrastructure development might be a localized threat to this species, but its range overlaps with many protected areas.
Its range includes several protected areas. More research into the species' extent of occurrence, ecological requirements and population status is needed.
