From the IUCN Red List Species Account:


Range Description

This species’ geographic range is in the Serra do Mar in the state of Santa Catarina, Brazil. It has an altitudinal range of 300-800m asl.

Habitat and Ecology

It was found in Atlantic forest fragments, at fast-running streams rushing over rocks. Adults and juveniles were found in the water and larvae were attached to rocks in the splash zone.


It was last collected in the late 1970s and recent surveys have failed to record it.

Population Trend


Major Threats

The major threats to this species are unknown. It has apparently disappeared from seemingly suitable habitat. It is possibly threatened by tourism.

Conservation Actions

Given the declines of high-altitude stream-breeding species in other parts of the wet tropics, surveys are urgently needed to relocate this species and to assess its status, especially in view of the lack of recent records. Some other Cycloramphus species have declined for unexplained reasons, and so it is an urgent priority to rediscover populations of this species.

Red List Status

Data Deficient (DD)


Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
