Flagellum 14­segmented, flagellomeres cylindrical, lengths about equal to widths, covered by setulae no longer than one­half flagellomere width. Palpi 4­segmented, three basal segments bacilliform, apical one short and rounded. Occiput, frons, face, and clypeus with short setulae. Thorax: Prescutum and anterior parapsidal suture distinct. Antepronotum with 6 setae, proepisternum with two. Scutum arched. Scutellar setae in rows. Scutellum with two pairs of long setae. Cavity on anterior edge of katepisternum shallow.

Length of crossvein r­m 0.5Χ length of section M3. M3 weak, can be seen only by absence of microtrichia on wing membrane. M and CuA fork base proximal to the base of r­m. M 3+4 interrupted at base, not reaching wing margin. Legs: Fore coxae with anterior setae, mid coxae with lateroapical ones. Tibiae without bristles. Genitalia: Gonocoxites massive, fused.
