This species is known only from two high-altitude localities in southern Brazil: Parque Nacional do Itatiaia, at Itamonte, in the state of Minas Gerais; and the Serra da Bocaina, in the northern part of the state of Sao Paulo. It might occur more widely. Its altitudinal range is 2,000-2,200m asl.
Habitat and Ecology
This species lives on the ground near fast-flowing streams in high-altitude grasslands. It breeds in the streams by larval development.
It is not common, but it can be found when being surveyed for.
Its major threats are probably related to habitat loss due to tourism and fire. It might also be adversely affected by freezing ice in the montane grasslands.
Parque Nacional do Itatiaia is the only protected area from which it is currently known.
Red List Status
