This species is known only from the type locality, Parque Nacional do Itatiaia, on the border of Rio de Janeiro State, Brazil, although it probably occurs more widely. The locality is somewhere between 500-1,000m asl.
Habitat and Ecology
During the day it is found on emergent rocks in shallow places in streams in primary forest. Eggs are laid under large rocks in moderately-sized forest streams, in which the larvae also develop.
The population status of this species is unknown, as it is known only from a few specimens. However, it is not considered rare, but just very difficult to catch as it is very agile.
The threats to this species are unknown, but the type locality is in a very secure national park, providing very good protection for its habitat.
Parque Nacional do Itatiaia is the only protected area from which it is currently known.
