Flagellum 14 segmented, flagellomeres cylindrical, lengths about equal to widths, covered by setulae no longer than onehalf flagellomere width. Palpi 4 segmented, three basal segments bacilliform, apical one short and rounded. Occiput, frons, face, and clypeus with short setulae. Thorax: Prescutum and anterior parapsidal suture distinct.

Laterotergites and mediotergite bare. Wing: Sc meets C just beyond level of base of M 3. C ends far beyond apex of R 5. R 1, R 5, and rm with setae. R 1 length 2 Χ that of rm. R 5 straight. Length of crossvein rm 0.5 Χ length of section M 3. M 3 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.
