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.
Céspedez (2000) separated the taxon formerly known as Rhinella pygmaea into two species: R. pygmaea of coastal Brazil and R. bergi in the interior of the continent.
