This species was previously known only from Amazonian Forest in the states of Amapá and Pará (Monteiro, 1960; Camras & Parrillo, 1985; Camras & Parrillo, 1996). This provides the first record for northeastern Brazil. The female and egg are herein described for the first time. Males with the same collecting data were identified by comparison with the holotype.
