"Pseudis" frogs live in tropical and subtropical South America. Almost all of them live east of the Andes, on the Atlantic side of South America. "P. paradoxa" is the only species in "Pseudis" that has any frogs living west of the Andes. These frogs live from Trinidad to northern Argentina but not in Ecuador or Chile. They live in hills and other highland regions, and they live in the southernmost part of South America. All species in this genus are found in Brazil.
