This species is known only from two nearby localities in the state of Bahia, eastern Brazil, Ilhéus and Una, where occurs up to 60m asl. It probably occurs more widely, but its distribution is very poorly known.
Habitat and Ecology
It lives in primary and secondary forest, and is probably an explosive breeder in temporary pools.
In 1999, after an absence of records for 50 years, it was rediscovered at Una, where many specimens were found. However, there is still no clear picture of its overall population status, and it is probably a very hard species to detect when it is not breeding.
The major threats to this species are probably related to habitat loss due to agricultural development, logging, tourism and human settlement.
It occurs in the Reserva Biológica de Una.
Red List Status
Data Deficient (DD)
