This species is known only from the type locality (Teresópolis) in Parque Nacional da Serra dos Orgãos in Rio de Janeiro State, Brazil. The altitude of the type locality is about 1,500m asl.
Habitat and Ecology
This species occurs on vegetation at the edge of streams in montane primary forest. It presumably breeds in permanent streams.
The population status of this species is unknown, although it is known from only two specimens and it has not been found recently, so it is possible that it is extinct.
There are several main threats facing this species. Although its known range is within a protected area, habitat degradation due to touristic activities is taking place within the area. There are also planned infrastructure developments for the park in which it occurs, and chytridiomycosis is also a potential threat.
This species' range is wholly within Parque Nacional da Serra dos Orgãos, where maintenance and conservation of its habitat is needed. More research is also needed to aid its conservation, in particular to determine whether or not it still survives at the type locality.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
This species was previously within the genus Hyla but has recently been moved to the genus Aplastodiscus (Faivovich et al. 2005).
