This species is known only from the Itatiaia Mountains at around 2,200m asl on the border of the states of Rio de Janeiro and Minas Gerais, in south-eastern Brazil.
Habitat and Ecology
It lives in primary forest in and around streams (in which it breeds) and cascades with clear running water. The males calls from stones or secluded places under rocks at the margins of the streams.
It is an uncommon species.
The major threats to this species are probably related to habitat loss due to logging, tourism and fire.
It occurs in Parque Nacional do Itatiaia.
