Diagnostic characters. General color dark brown, length of fore wing 11 mm , subgenital plate a broad apically narrowly notched plate covering part of sternum 9; hind margin of large tergum 10 extended, center of segment densely covered with short setation, paraprocts slender, with conspicuous subapical angle delimiting bare acute tips in lateral and ventral views ( Zwick 1984 ). FIGURE 3. Gripopteryx brasiliensis , male: a, head and pronotum, dorsal view; b, terminalia in dorsal view; c, terminalia in lateral view; d, terminalia in ventral view. FIGURE 4. Gripopteryx brasiliensis , female: a, terminalia in dorsal view; b, terminalia in ventral view; c, terminalia in ventrolateral view. Remarks. G. serrei was based on only one female with dark wings. It was synonymized with G. cancellata by Illies (1963) . Zwick (1984) redescribed the type and admitted the possibility of G. serrei being synonymous with G. cancellata . However, after analyzing the type material of G. cancellata and comparing with the redescription and pictures of Zwick (1984) we conclude that they are distinct species. In G. s e r re i the paraprocts end in bare acute tips and the subgenital plate is bilobed, against the rounded paraprocts and the straighter subgenital plate of G. cancellata .
