This species is known from the type locality (Parque Nacional do Itatiaia, on the border of Rio de Janeiro and Minas Gerais States) and from Serra do Japi in Sao Paulo State, Brazil. It has been recorded between 800-2,000m asl. It presumably occurs in suitable habitat between these localities.
Habitat and Ecology
It is a diurnal species found in streams in primary and secondary forest. It presumably breeds in the small rivulets and the tadpoles develop in the streams. It has not been recorded outside forest.
It is a common species.
Livestock farming was a threat in the past in Serro do Japi. Fire might also be a threat at this locality, and there is also disturbance from military activities and tourism.
Both of the known localities are within protected areas; Parque Nacional do Itatiaia and Parque Municipal da Serra do Japi. Conservation and maintenance of its habitat is required. More research into the species' Extent of Occurrence, ecological requirements and population status is needed, in particular to determine if it occurs outside the two known localities.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
