From the IUCN Red List Species Account:


Range Description

This species is known from the eastern state of São Paulo, in Brazil. It has been recorded from 800-1,000m asl.

Habitat and Ecology

This species occurs on stones in primary and good quality secondary forest streams. Larvae are found on rocks that are covered with a film of running water, either on exposed rocks in or next to streams. It has not been recorded outside forested habitat.


It is a reasonably common species.

Population Trend


Major Threats

Air and water pollution from industry, and disturbance of the species' habitat by touristic activities are major threats.

Conservation Actions

Its range includes a few protected areas. More research into the species' Extent of Occurrence, and population status is needed, in particular to determine whether or not its range is much larger than currently known.

Red List Status

Least Concern (LC)


Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
