Distribution. China (Sichuan, Yunnan, Tibet) ( Fig. 109 ).

Female ( Figs 31, 32 ): Body length 8.5–9.5 mm. Body muddy yellow, black are: apical half of frons continuing with ocellar area, under margin of occiput, dorsal part of antenna, anterior margin on median part of pronotum, a large central spot on median mesoscutal lobe, lateral mesoscutal lobe except a central butterfly-shaped spot and lateral margins, most of meseparapsis, lower part of meteparapsis, posterior margin of metapostnotum, central band each on terga 2–8, apex of ovipositor sheath. Legs muddy yellow, black are: a narrow stripe each on dorsal part of four front legs from basal 2/3 of femur to claw, a narrow stripe each on outer side of metacoxa and metafemur, an inner band on metacoxa, an apical 1/3 inner stripe of metafemur, dorsal part and apex of metatibia, metatarsus except basal ventral side of each tarsomere. Wings hyaline, fore wing vein C, R1, 2r and stigma pale green, other veins dark brown. Punctures on dorsal part of head large, but sparse, microsculpture dense, luster indistinct; punctures on upper part of mesepisternum shallow, minute and scattered, on lower part extremely minute and shallow, interspaces shiny; punctures on mesoscutellum indistinct, microsculpture dense, interspaces slightly shiny. Malar space 3 times diameter of median ocellus; median fovea ditch-like, shallow; postocellar area slightly elevated, 1.67 times as broad as long ( Figs 55 , 72 ); antenna shorter than combined length of thorax and abdomen, flagellomere 1 about 1.1 times length of flagellomere 2. Mesoscutellum distinctly elevated, disc round, without lateral ridge. Ovipositor sheath slightly shorter than hind tarsomere 1 in lateral view, valvula 3 round at apex and as long as valvifer 2 in lateral view. Lancet with 19 serrulae, (Fig. 85), base of each serrula distinctly elevated, middle serrulae each with basal denticles and 6–7 distal denticles (Fig. 97).

Male. ( Figs 33, 34 , 56 , 73 ): Body length 7.5 mm. Color and structure similar to female, otherwise: malar space about 3 times as diameter of median ocellus; postocellar area 2 times as broad as long; antenna longer than combined length of thorax and abdomen, flagellum strongly compressed; gonoforceps and penis valve as in Figs 101, 106 .

Variation. The width of black band on abdominal terga varies from 1/6–3/5 of width of tergum.
