This species is known from two localities in the state of Bahia in eastern Brazil; near Fazenda Unacau in São José da Vitória Municipality; and from a locality in Uruçuca Municipality (Dixo and Verdade 2004). It occurs up to 180m asl.
Habitat and Ecology
The type specimen was collected among rocks about 100m from a stream. The large distance between the collection site and the stream suggests that it is not stream-dependent, and the species' morphology is similar to that of the other forest floor species with terrestrial larvae, such as Cycloramphus stejnegeri.
There is no information and there have been very few records.
The major threats to this species are probably related to habitat loss due to agricultural development, creation of wood plantations, logging, fire and human settlement.
Some other Cycloramphus species have declined for unexplained reasons, and so it is an urgent priority to rediscover populations of this species.
