This species is known only from Serra dos Orgãos in Rio de Janeiro State, Brazil. It has been recorded between 800-1,200m asl.
Habitat and Ecology
This species lives in leaf-litter on the forest floor, or on low vegetation, and breeds in terrestrial bromeliads inside primary or secondary forest. The eggs are not laid in the water of the bromeliad but on the axil of the outer leaves. It is an amphibian that breeds by direct development. It has not been recorded outside forest habitat.
It is a common species.
Habitat loss due to clear cutting of the forest was a threat in the past. Infrastructure development for human settlement is an ongoing threat, even inside some protected areas.
The range of the species overlaps with a few protected areas. More research into the species' Extent of Occurrence is needed.
