This species from southeastern and eastern Brazil ranges from the northern part of the State of São Paulo, north to the southern part of the State of Bahia. It occurs up to 1,200m asl. The animals in São Paulo probably belong to a separate, undescribed species.
Habitat and Ecology
It is found in flooded areas, or near temporary and permanent ponds, inside or at the edge of primary and secondary forest. It does not occur outside forest. The eggs are laid in foam nests on the leaf-litter or mud near temporary and permanent ponds, in which the larvae develop. Reproductive activity has been reported for the month of November, with the potential of also occurring in October, although longer breeding periods are also known to occur (Abrunhosa et al., 2006).
It is a very common species.
The major threats are probably related to habitat loss due to agriculture, wood plantations, livestock grazing, logging and human settlement.
It occurs in many protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
