This species is widespread in southern, southeastern and central Brazil as well as in eastern Bolivia, Paraguay, northern Argentina, and northern Uruguay. Its altitudinal range is from 0-2,000m asl.
Habitat and Ecology
It occurs in open habitats such as pastures. During breeding time it can be found in standing waterbodies, such as ponds. The spawn are attached to aquatic vegetation and the tadpoles develop in the water. It is very common in urban areas, and inside houses.
It is common even in deforested regions.
There are no threats.
It occurs in several protected areas. Taxonomic work is required to resolve this species complex.
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 to qualify for listing in a more threatened category.
This form is probably a complex of several species. Scinax trachythorax and S. megapodius are treated as separate species by some authors, but the most recent review of Hylidae considers them both to be a synonym of S. fuscovarius (Faivovich, et al., 2005).
