This species occurs in the southernmost part of the Atlantic forest in the states of Santa Catarina and Rio Grande do Sul, southern Brazil, from 300-1,000m asl.
Habitat and Ecology
This species lives in forested areas on rocky cliffs; eggs are deposited under waterfalls on rocks.
It is rarely collected, although it was found in 2001, and it appears to have disappeared from some localities.
Some populations of this species have been affected by changes in watercourses, and by sedimentation caused by road construction, as well as by general forest loss. However, these factors do not fully account for the recorded declines. Like amphibians in some other parts of the wet tropics, it appears to have disappeared from areas of apparently suitable habitat, and chytridiomycosis cannot be ruled out as a threat, even though this disease has not yet been confirmed from Brazil.
This species occurs in Parque Nacional da Serra Geral and Parque Nacional de Aparados da Serra. Given the possible threat of chytridiomycosis, there is a need for close monitoring of the population status of this species.
Red List Status
Near Threatened (NT)
Listed as Near Threatened because, although its Extent of Occurrence is less than 20,000 km2, it occurs in a habitat that is not under significant threat, and so it is probably not in decline.
