This species occurs in the eastern, central and upper Amazon Basin of Brazil, from Cerro Marahuaca in Amazonas state, Venezuela, in the lower Amazonian slopes of the Andes, Amazonas and Putumayo departments, Colombia and Peru, at 0-800m asl. The records in Venezuela might belong to a different, as yet undescribed species, but pending resolution they are included here.
Habitat and Ecology
It lives in secondary and old growth tropical rainforest on the forest floor. Reproduction occurs in small pools, the eggs are laid out of water and the tadpoles carried to the water.
It is common, and the population is stable.
Clear cutting, logging, forest conversion and fires are threats to this species.
Several protected areas are present within its range.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
