This species from the mountains of southeastern Brazil ranges in southern Rio de Janeiro and northeastern São Paulo States, and adjoining southeastern Minas Gerais (Napoli, 2005). Its altitudinal range is 800-1,200m asl.
Habitat and Ecology
It lives in primary and secondary forests, and forest edge and clearings inside forest. It is usually found on vegetation in the forest and in clearings, near or away from streams. It breeds in streams where it constructs nests in mud.
It is a common species, but has declined in some locations (Eterovick et al., 2005).
The major threats are probably related to habitat loss due to clear-cutting and human settlement. This species has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).
It occurs in many protected areas.
This species was previously within the genus Hyla but has recently been moved to the genus Bokermannohyla (Faivovich, et al., 2005). The taxon in southern Espírito Santo State has recently been separated as B. caramaschii (Napoli, 2005).
