Krisna concava Li & Wang, 1991:298 View in CoL , figs. 10–16.

Krisna bimaculata Cai & He, 1998:23 View in CoL , figs. 4, A–G. syn. nov.

Pale stramineous to yellowish brown, anterior rim of vertex pale red. Spot at base of forewing appendix piceous.

Head slightly longer medially than next to eyes. Disc of vertex slightly depressed. Face rather flat, male with small knob between antennae. Clypellus strongly broadened apicad, 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 eighth sternite with hind margin convex.

Male genitalia: Pygophore elongate, with many macrosetae posteriorly; ventral pygophore process curved dorsally near apex, shorter than length of pygophore. Style very long, apophysis long and narrow, slightly curved dorsally near apex with thickening not extending half width at apex. Aedeagus robust at base, with short preatrium, dorsal margin straight in lateral view, distal 1/3 upturned, narrowed with transverse rugae, in caudal aspect, base of shaft broader than apical region; phallotreme apical on ventral surface.

Measurements: Male 11.8–12.5mm long, 2.9–3.0mm wide across eyes, 3.9–4.0mm wide across hind margin of pronotum. Female 14.1–15.0mm long, 3.3–3.4mm wide across eyes, 4.4–4.5mm wide across hind margin of pronotum.

Material examined: Paratype China: Guizhou Prov., 1ɗ, Wuchuan, 6 July 1985, Qin Ju’an, Krisna concava Li & Wang ( GZU); Hunan Prov.: 2ɗ, Hupingshan, Quanpingcun, 900m, 17 July 2006, Lv Lin; 1ɗ, Chenzhou, 28 July 1985, Zhang Yalin and Chai Yonghui; Sichuan Prov.: 2ɗ, Qingchengshan, 1100m, 8 July 2005, Li Meng, at light ( NWAFU).

Distribution: China (Guizhou, Henan, Hunan, Sichuan).

Remarks: This species was described based on two male specimens collected from Guizhou Province. Cai and He (2004) described a new species, Krisna bimaculata , from Henan Province of China, which is treated here as a junior synonym of Krisna concava Li & Wang based on examination of the paratype male and additional material.
