Hypoclypeal depression absent or narrow, and medially ventral margin of clypeus near upper level of condyli of mandibles ("mouth closed"); mandible strongly twisted, its second tooth hardly visible in lateral view, and with a medium-sized to large ventro-basal tooth, but minute or obsolescent in the subgenus Snoflakopius Fischer (stat. n.); pronope usually absent and at most medium-sized; pterostigma sublinear; vein 3-SR of fore wing 1.4 times vein 2-SR or longer; 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.
