Diagnosis – Metope elongate, weakly convex laterally, with median carina running from its upper margin or its middle to postclypeus via metopoclypeal suture and with sublateral carinae running from its upper margin to metopoclypeal suture. Coryphe transverse. Pronotum with convex anterior margin and straight posterior margin; paradiscal fields very narrow behind the eyes. Forewings oval or nearly rounded, without hypocostal plate; radius bifurcate, but often fused apically forming an elongate loop, median bifurcate apically, cubitus anterior simple or furcating apically, cubitus posterior distinct only in its proximal half, postcubitus simple. Cubitus posterior and postcubitus sometimes fused apically. Reticulate venation scarce or rich. Hind wings rudimen­ tary. Hind tibia with 1–2 lateral spines. First metatarsomere nearly as long as second one or 1.5–2.0 times longer. Phallobase wide, weakly curved (in lateral view), with wide processes covering ventral aedeagal hooks. Aedeagus with a pair of long ventral hooks directed basally. Connective with large cup. Styles with large plate and small bifurcating capitulum (in dorsal view). Gonoplacs rounded, with dorso­caudal angles in lateral view not protruding above the apex of anal tube.
