From the IUCN Red List Species Account:


Range Description

This species occurs in the Serra do Mar in the states of Paraná, São Paulo and Rio de Janeiro, in southern Brazil, at 500-900m asl.

Habitat and Ecology

This species is associated with fast-flowing streams and waterfalls in primary and old secondary forest. It sometimes hide in rock crevices. The larvae presumably develop out of the water in the splash zone of waterfalls, as is the case with other Cycloramphus species.


It has not been found since the original collections, when it was common. It is not known whether or not the lack of recent records is due to insufficient survey effort, or whether or not there might have been a genuine decline.

Population Trend


Major Threats

The major threats to this species are probably related to habitat loss due to agricultural development, creation of wood plantations, logging, tourism and human settlement.

Conservation Actions

It occurs in the Reserva Particular do Patrimônio Natural Gaia in Paraná State. 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.
