This species’ geographic range is the most southerly extent of the Serra Geral in the states of Santa Catarina and Rio Grande do Sul, Brazil, where it is found from 400-900m asl.
Habitat and Ecology
This species occurs in rainforest in fast-moving rocky streams, in which it reproduces. The larvae attach themselves to rocks in the splash zone.
It has not been recorded since 1982, perhaps due to a lack of survey work.
Road construction has altered streams where this species was once found, and might constitute a threat to it.
It occurs in Parque Nacional da Serra Geral and Parque Nacional de Aparados da Serra. 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.
