This species is known from eastern Venezuela, Guyana, Suriname, French Guiana, and Amapá and Amazonas states, in Brazil. It was recorded from only two localities in Brazil. As these localities are on opposite sides of the Amazon region, it is likely that the species has a much wider distribution than is mapped here. It has been recorded from 30-1,460m asl.
