From the IUCN Red List Species Account:


Range Description

This species is known with certainty only from above 800m asl in the Serra des Órgãos, in the state of Rio de Janeiro, south-eastern Brazil. There are historical records from mountain tops in the state of São Paulo, but there are no recent records from this state. A record from Santa Teresa in the state of Espírito Santo requires confirmation.

Habitat and Ecology

It is found in rocky areas in forest, or on the forest edge, living on wet rock walls near streams or waterfalls. The egg clutch is deposited in rock fissures.


It used to be common, but it has now undergone significant declines. For example, whereas it was once abundant and easy to find (at least up until 1979) at Teresópolis, Serra dos Órgãos, in Rio de Janeiro State, it has not been recorded since.

Population Trend


Major Threats

The major threats are probably related to habitat loss due to clear-cutting, human settlement, tourism, and fire. However, this does 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.

Conservation Actions

It occurs in the Parque Nacional da Serra des Órgãos. However, the park is urgently in need of an improved management plan to accommodate increased tourist traffic to the area. There is a need for further research to investigate the reasons for the decline of this species in apparently suitable habitat.

Taxonomic Notes

The identity of populations outside the state of Rio de Janeiro require clarification.
