This species occurs widely in southeastern Brazil in the States of Espírito Santo, southern Minas Gerais, Rio de Janeiro, São Paulo, and possibly elsewhere. It ranges up to 800m asl.
Habitat and Ecology
It lives on the floor of primary and secondary forest in the leaf-litter, and does not occur in open habitats. It breeds by direct development, and eggs have been found in a low bank of earth.
It is a very common species. It has experienced a population decline at Estação Biológica de Boracéia (Eterovick, et al., 2005).
The major threats are probably related to habitat loss due to agriculture, wood plantations, logging, fires and human settlement.
It occurs in several protected areas. Population monitoring is needed to determine the current status of the populations in Estação Biológica de Boracéia.
