This species is known only from the type locality, Quecaba, Aguas Mornas, in Santa Catarina, Brazil, from 300-500m asl.
Habitat and Ecology
It occurs in Atlantic forest, probably in streams, in which it is likely to breed.
Its population status is unknown, since it was collected over 50 years ago.
The major threats are unknown.
The type locality is very close to Parque Estadual da Serra do Tabuleiro. 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.
