Hypoclypeal depression absent or narrow, and medially ventral margin of clypeus near upper level of condyli of mandibles ("mouth closed"); clypeus comparatively sparsely and short setose, if rather long and dense then clypeus flattened; mandible with ventro-basal carina, rarely obsolescent or on a small protuberance (resembling a small tooth); epistomal suture present; if suture is shallow then basal half of vein M+CU1 of fore wing largely unsclerotized; vein 3-SR of fore wing 1.3 times vein 2-SR or less, if rarely 1.4-1.5 times then pronope very large or pterostigma triangular; mesosternum normal, much longer than fore coxa; hind coxae normal, rounded ventrally; second-fourth tarsal segments comparatively slender; telotarsus and arolium not enlarged; dorsope usually large and close to lateral margin of first tergite; hypopygium of female at most slightly incised.
