From the IUCN Red List Species Account:


Range Description

This species is known only from the type locality, the Estação Ecológica da Juréia-Itatins, in Iguape, São Paulo State, Brazil. The type locality is at around 200m asl.

Habitat and Ecology

This species was found in a waterfall habitat at the edge of the rainforest. Males called from steep rock surfaces or in rock crevices, sitting near or under waterfalls. Larvae are presumably found on rocks that are covered with a film of running water, either on exposed rocks in or next to streams, as with other species in the genus.


It has not been recorded again since it was first collected, so its population status remains unknown.

Population Trend


Major Threats

The major threats are unknown, but its known range is within a protected area. Some other Cycloramphus species have declined for unexplained reasons, and so it is an urgent priority to rediscover populations of this species.

Conservation Actions

Estação Ecológica da Juréia-Itatins is the only protected area from which this species is currently known. 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.

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.
