This species occurs in coastal southeastern Brazil, in Rio Grande do Sul, and Santa Catarina states, at 0-200m asl.
Habitat and Ecology
It was presumably originally a forest species. However, it adapts well to rice fields and other agricultural habitats. It occurs in vegetation surrounding seasonal and permanent pools. It reproduces in water.
It is very common and the population is stable.
Water pollution is possibly a threat to this species.
It does not occur in any protected area, but it is able to live in agricultural areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Hypsiboas (Faivovich, et al., 2005). It was formerly considered by some authors (i.e., Miranda Ribeiro 1926; Barrio 1962) to be a synonym of Hypsiboas pulchellus.
