This species is known only from very low altitudes, up to 40 m asl, in the states of Rio de Janeiro and São Paulo in southeastern Brazil, with disjunct populations in the southern part of the state of Bahia in eastern Brazil. However, it might occur more widely than current records suggest.
Habitat and Ecology
It is found in primary and secondary forest, but not in open areas. It has been observed in temporary ponds inside lowland forest, and is known to be an explosive breeder.
It is an abundant species.
The major threat is habitat loss due to agriculture (including wood plantations and livestock grazing), logging, and human settlement.
It occurs in several protected areas, although there is still a need for expanded protection of Atlantic forest habitats in this region of Brazil.
Red List Status
Listed as Endangered because its area of occupancy is probably less than 500 km2, its distribution is severely fragmented, and the extent of its forest habitat in the Atlantic Forests of Brazil is probably declining.
