This species is known from the Serra dos Órgãos and Serra da Mantiqueira, in Rio de Janeiro State, Brazil, from 800-1,200m asl.
Habitat and Ecology
It occurs on rock wall seeps and in forest streams in primary and good quality secondary forest. Larvae have been observed on rocks that are covered with a film of running water, either on exposed rocks in or next to streams.
This is not a common species.
Habitat loss due to infrastructure development for human settlement is a major threat, and this is taking place in some protected areas, even though this is illegal.
The range of the species includes several protected areas, but there remains a need for improved conservation and maintenance of existing habitat.
