This species is known from open formations of Paraguay south to Uruguay (Salto Department), adjacent Argentina, Bolivia, central and western Brazil, and extending along the Rio Madeira and Rio Amazonas within the Amazon basin. An outlier population occurs in Igarapé Belém, Amazonas, Brazil. It occurs up to 1,000m asl.
Habitat and Ecology
It lives in grasslands and open habitats, often living near ponds and flooded areas. It lays eggs in foam nests at the edges of permanent and temporary ponds and flooded areas, whether or not covered or cleared of vegetation, but generally in shaded areas about 5 cm deep. It appears to adapt well to anthropogenic disturbance (occurs in urban areas in northern Argentina).
It ranges from rare to very common throughout its range (common especially in suitable habitat).
There are no major threats to this species.
It occurs in several protected areas.
This species is in the Leptodactylus melanonotus Group, Leptodactylus wagneri-Leptodactylus podicipinus complex.
