This species is known only from the southern and central parts of the State of Bahia, eastern Brazil, from Guaratinga north to Santa Teresinha. It occurs up to 800m asl.
Habitat and Ecology
It lives in lowland moist forests and in cocoa plantations. It is adaptable to more open areas, providing that trees are present. It has been found in the leaf-litter in cocoa plantations and in bromeliads in forest. It presumably breeds by direct development, but it is not known where it lays its eggs.
It is a common species.
The major threats are probably related to habitat loss due to agriculture, livestock grazing, logging, industry and human settlement.
It occurs in several protected areas.
