Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. S. Aristov 2002 | Head diametral, moderately large; eyes small, round; antennae thin. Pronotum smaller than head, rounded; paranota broad with cut in anterior margin. Mesonotum large, its width more than length; prescutum small. Metanotum similar to mesonotum, but smaller.
Forewing: Anterior margin convex, apex rounded, posterior margin convex. Costal area wide (three to four times wider than subcostal) with dense ridge of fore branches of SC. SC extend to distal thirds of wing. R nearly straight, RS originates near middle of wing, parallel to R, radial area very narrow. M dividing early, basal parts of M free. MA connected with origin of RS by strong crossvein, MAarea wide with slightly curved crossveins, MP closed together with CuA. CuA S-shaped, with hind branches in basal part of CuA-area. Cup weak, AI simple, almost straight. Hindwing: Anterior margin straight, apex rounded. Costal area two times wider than subcostal; SC ending in distal quarter of wing; CuA straight. Abdomen does not reach apex of wings, narrowing to apecal; ovipositor probably short. |
