Male Pp: apical part long and wide; Fp long and wide, divided from Rp. Male Sg: fused with St 9 and Tg 9, vesicle absent. Female Sg: pointed and incised, slightly overhanging, lateral sclerites present. Male tergites: process lacking. Ventral thoracic sclerites: MPrs and MeFs triangular, MeFsp separated from MePfs. Macropterous wings: forewing A1 beyond a and R1 before r curved.
