This high-altitude species is known only from Parque Nacional do Caparaó, in the state of Minas Gerais in south-eastern Brazil, where it occurs at around 2,300m asl. It might occur more widely.
Habitat and Ecology
It is associated with streams, in which it presumably breeds, in open high-altitude grassland.
Only a few specimens are known. The lack of subsequent records appears to be related to a lack of surveys, and there is insufficient information to know whether or not this species is common or rare.
The main threat to this species is probably habitat loss due to fire and the effects of tourism.
Parque Nacional do Caparaó is the only protected area from which it is currently known.
Red List Status
