Habitat and Ecology
A terrestrial species occuring in open areas, on the ground near waterbodies. It deposits its eggs in foam nests in terrestrial burrows, and the larval development takes place in temporary ponds and flooded grasslands. It is also found in urban areas in southern Brazil.
It is uncommon in Bolivia and Paraguay, but common in southern Brazil, Uruguay, and Argentina.
There are no major threats to this species.
Taxonomic research to resolve this species complex is needed. It occurs in several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species is a complex of more than one species.
