This species is known from Colombia, Venezuela, French Guiana, Guyana, Suriname, northeastern and central Brazil, Ecuador, Peru and Bolivia. It does not occur as far south as Paraguay (Heyer, 1978). It occurs up to 1,000m asl.
Habitat and Ecology
It inhabits primary and secondary tropical rainforests, forest edge, and savannah enclaves in forest, flooded and open environments. It lives on the ground around temporary ponds and other waterbodies. The males construct basins in muddy areas that are flooded by heavy rains. Eggs are laid in foam nests, and the tadpoles develop in lentic water. It is adaptable to human modification of its habitat.
It is a fairly common species.
There are no major threats to this widespread and adaptable species. Fire, clear cutting, logging, infrastructure development and agricultural expansion might impact local populations.
Its range includes several protected areas.
