This species is endemic to southeastern and southern Brazil in the States of Minas Gerais, Rio de Janeiro, São Paulo, Santa Catarina, Parana, and Rio Grande do Sul. It occurs at intermediate elevations at 800-1,400m asl.
Habitat and Ecology
It lives in forested habitats, and in grassland and pastureland, and is usually found on vegetation near ponds, pools, and lakes. It breeds in permanent pools and small streams, and the egg clutches are attached to vegetation in the water.
It is a common species. In Estação Biológica de Boracéia in São Paulo State, the species appears to have disappeared. The decline has been linked to the higher abundance of H. albopunctata.
The main threats are water pollution, and loss of habitat due to fire.
It occurs in several protected areas.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005).
