This species occurs in Serra do Mar and Serra da Mantiqueira in Rio de Janeiro, Paraná, Minas Gerais and São Paulo States, as well as Ilha Grande in the state of Rio de Janeiro, in Brazil. It has been recorded from 800-1,200m asl, but in Ilha Grande it has been recorded at sea level.
Habitat and Ecology
This species occurs near rivulets and temporary ponds in primary and secondary forest. Subterranean nests are built in muddy soil or banks near the waterbodies. The tadpoles live in permanent streams. It has also been found in anthropogenic habitats such as gardens, plantations, etc.
It is a very common species.
There are no known threats to this species. Clear cutting of forests could be a localized threat but it is not currently occurring within its range.
A similar species (Aplastodiscus cf. leucopygius) has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
The range of the species includes several protected areas. Conservation and maintenance of its habitat is needed. More research into the species' Extent of Occurrence is desirable.
This species was previously within the genus Hyla but has recently been moved to the genus Aplastodiscus (Faivovich, et al., 2005).
