Krisna nigromarginata Cai & He, 1998: 21 View in CoL , figs. 2, A–G.

Fuscous. Vertex, pronotum and scutellum greenish ochraceous. Anterior rim of vertex piceous. Forewing with coast margin yellow.

Head slightly longer medially than next to eyes, fore margin reflexed. Disc of vertex slightly depressed. Upper part of frontoclypeus depressed. Clypeus with median ridge in basal half. Pronotum more than 3 times as long as head, slightly wider than long, scutellum as long as pronotum.

Male genitalia: Pygophore elongate, with a long ventral process directed to caudal margin slightly curved dorsally, with a short pointed process on ventral margin at each side in lateral view, with many macrosetae posteriorly. Style very long, apophysis long, narrow, rectangular curved dorsally at apex without thickening. Aedeagal shaft robust near base, curved dorsally and narrowed to apex with short rugae near apex in lateral view, hind margin convex, in caudal view, widened near apex, then narrowing towards apex; phallotreme apical on ventral surface.

Measurements: Male 10.0mm long, 2.6mm wide across eyes, 3.1mm wide across hind margin of pronotum.

Material examined: 1ɗ, Guangxi Prov., Guangnan, 23 Aug. 1982, Wang Yunzhen ( KIZ).
