From the IUCN Red List Species Account:

 

Range Description

This species is known only from the type locality, São João da Graciosa, Serra do Mar in the state of Paraná, Brazil. It has an altitudinal range of 50-150m asl.

Habitat and Ecology

It occurs in fast-flowing rocky streams in lowland forest and it reproduces in streams.

Population

The population is unknown. It has not been collected since the original collection in the late 1970s.

Population Trend

unknown

Major Threats

The major threats are unknown. It is possibly threatened by tourism. Some other Cycloramphus species have declined for unexplained reasons, and so it is an urgent priority to rediscover populations of this species.

Conservation Actions

It occurs in Serra da Graciosa State Park. The creation of new protected areas and research actions are needed. 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

Least Concern (LC)

Rationale

Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under threat, it has a presumed large population, and it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
