This species is known only from Parque Nacional da Amazônia (along Rio Tapajos) in Brazil, at 100m asl.
Habitat and Ecology
It occurs in lowland primary and secondary rainforest, and is adaptable to some habitat modification. It lays its eggs on land, and the larvae are then carried to water by the adults, where they continue their development.
It is a common species.
Clear-cut logging and fires are major threats to this species' habitat.
Its range is in a single protected area: Parque Nacional da Amazônia.
Assessors at the Amazon GAA workshop in Brazil raised questions as to the taxonomic validity of this species, but Morales (pers. comm.) is convinced that it is a valid species.
