Note: In view of its distribution (Paranaense Forests of the Amazonian Dominion, and one old record in Tucumán), the type locality may be erroneous. This species was never found along gallery forests, southwards from the humid forests in eastern Paraguay, the province of Misiones and north of Corrientes.
