This species is known from coastal mountains in Rio de Janeiro, São Paulo and Paraná States, Brazil. It occurs from 50-1,200m asl.
Habitat and Ecology
This species occurs on vegetation near streams inside primary and secondary forest. The eggs are laid on leaves above the water, and when the tadpoles hatch they drop into the permanent stream below. It has also been found at the forest edge, but not outside forest.
This is a common species where it is found. It has undergone large population fluctuations in the past. Current declines in Rio de Janeiro need further monitoring to determine whether or not they are populations fluctuations or actual declines.
Habitat loss due to deforestation and infrastructure development are major threats to this species.
The range of the species includes several protected areas. More research into the species' Extent of Occurrence and ecological requirements is needed.
