This species occurs on the Araucaria plateau; Rio Grande do Sul, Paraná and Santa Catarina states; Brazil; at 800-1,100m asl.
Habitat and Ecology
It occurs in open savannah, and it is absent from closed-canopy forest. It is mainly found in the backwaters of small streams, and in the seasonal and permanent pools where it reproduces.
It is abundant and the population is stable.
Water pollution is a localised threat to this species. It is, however, fairly adaptable to habitat disturbance and very good at dispersing.
It occurs in several parks and protected areas.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005).
