Glenurus heteropteryx Gerstaecker, 1885

Glenurus heteropteryx can be easily distinguished from any other species on the genus because of its mostly transparent forewing (Fig. 2a), all other eight species present a large apical brown band in the forewing. The species was initially described from Panama and was later mentioned by Stange (2002) as possibly also occurring in Costa Rica. Posteriorly it was recorded from some of the Caribbean islands (Trinidad and Guadeloupe) and also from South America (Ecuador, Colombia, and Venezuela) (Stange 2004; Ardila-Camacho et al. 2014; Giacomino 2015). Herein I report the first record of G. heteropteryx from Brazil, one specimen collected in the northern state of Roraima (Fig. 5).

Examined specimens. Brazil: Roraima: Ilha de Maracá, 20–30.iii.1987, Luis S. Aquino (1♀ INPA) .
