This species occurs in the lowland forests of Pará, Maranhão and Tocantins states, Brazil. It probably occurs more widely, in particular between known sites.
Habitat and Ecology
It lives in the leaf-litter of the tropical rainforest, and reproduction takes place in temporary pools. Eggs are laid on the ground and the tadpoles are carried to the water.
It is locally abundant.
Forest conversion, logging, fire and the international pet trade are threats to this species. The populations in Tocantins state are threatened by hydroelectric development.
Conservation units are present within its range.
