This species is found in remnants of the Atlantic rainforest in the state of Alagoas at Maceio and Rio Largo, in north-eastern Brazil. All records are from near sea level.
Habitat and Ecology
It is found in primary and secondary forest, living on the ground in leaf-litter or under fallen palm leaves, and is not found outside forest. It shows a preference for humid sites, and is probably an explosive breeder in temporary ponds.
It is hard to find, and its population status is unknown.
The major threats to this species are probably related to habitat loss due to agricultural development, livestock grazing and human settlement. The area where it is found is suffering from severe fragmentation and reduction of forest patches.
It is not known from any protected areas.
