Distribution. China (Sichuan, Yunnan, Qinghai) ( Fig. 107 ).

Female ( Figs 3, 4 ): Body length 8.5–9 mm, black are: posterior half of frons continuing with most of ocellar area, lateral furrow, a band on temple, a spot on upper part of the occiput, dorsal part of antenna, median part of pronotum, posterior margin of tegula, a large spot on median mesoscutal lobe, lateral mesoscutal lobe except a central butterfly-shaped spot, meseparapsis except upper margin, meteparapsis, a small band on lower part of mesepisternum, median part of mesopleural suture, abdominal terga except a broad triangular spot on posterior part of each tergum, apical margin of ovipositor sheath. Legs muddy yellow, black are: a stripe on each dorsal part of four front legs from trochanter to claw, a large spot on inner side of metacoxa, a spot on outer side of metatrochanter continuing with base of metafemur, apex of metatibia, apex of each metatarsomere; red brown are: apex of metafemur, metatibia entirely, most of each metatarsomere. Wings hyaline, fore wing vein C and stigma muddy yellow, other veins black. Punctures on dorsal part of head large, deep and dense, microsculpture dense, luster distinct; upper part of mesepisternum moderately and uniformly punctured, punctures on lower part minute and shallow, distinctly shiny; disc of mesoscutellum polished, punctures almost absent, strongly shiny, posterior part with dense punctures, punctures on posttergum dense, luster indistinct. Malar space 3 times diameter of median ocellus; median fovea shallow and narrow; postocellar area slightly elevated, 2 times as broad as long ( Figs 41 , 58 ); antenna shorter than combined length of thorax and abdomen, flagellomere 1 about 1.05 times length of flagellomere 2; mesoscutellum not elevated, disc flat, apex with distinct ridge. Ovipositor sheath as long as middle tarsomere 1 in lateral view, valvula 3 acute at apex and slightly longer than valvifer 2 in lateral view. Lancet with 19 serrulae (Fig. 75), base of each serrula oblique, middle serrula each with 3 basal denticles and 10–14 distal denticles (Fig. 87).

Male. Unknown.

Variation. Some specimens without black spot on temple; one female collected in Deqin 11km SE ( China) has a rather pale meseparapsis, lower part with dark brown spot; abdominal terga of another female collected in Shangri-La = Zhongdian 40km SSE rather black, terga 1–5 only with narrow pale hind margin, terga 6–8 dorsally completely black.
