Head in frontal view 1.20 × as wide as high; in dorsal view width 1.74 × length, with interocular distance 0.18 × head width and less than width of eye; in lateral view 1.51 × as high as long. Eye height about equal to width in lateral view; distance between eyes below 3.99 × distance between eyes above; malar space 0.42 × eye height; distance between toruli greater than distance between torulus and clypeal margin, and greater than distance between torulus and orbit. OOL: POL: LOL: MPOD = 1.0: 6.7: 10.7: 10.6. Face with parascrobal region narrow, interantennal region reticulate ( Fig. 7F View Fig ), scrobal depression ( Fig. 7F View Fig ) deep and ∩-shaped, imbricate, dorsal margin delimited, separated from anterior ocellus by distance equal to 1.21 × diameter of anterior ocellus; lower orbit slightly lower than level of dorsal margin of torulus; lower face coriaceous; vertex and temple imbricate. Antennal ( Fig. 6G View Fig ) scape and pedicel green with yellowish-red metallic luster, 1 st to 3 rd segments of funicle with blue to rusty luster basally, 4 th to 8 th segments and clava dark brown; scape normal, not expanded; relative length(width) of scape = 40(7), pedicel 12.8(4.8), 1 st to 8 th funiculars: 5.2(5), 16(5.2), 16.5(6.5), 16(8), 13(8.5), 11(9.6), 10(10), 8(11), clava 14.5(8.5).

MESOSOMA. Pronotum in dorsal view ( Fig. 6B View Fig ), dark with yellowish-green to blue metallic luster, setae hair-like and brown; divided medially, pentagonal, imbricate. Mesoscutum ( Fig. 6B View Fig ) slightly convex anteriorly and concave posteriorly, and with lateral lobe carinate posteriorly; dark with yellowish-green metallic luster, setae of mesoscutum brown and hair-like except lower portion of lateral lobe white and hair-like. Scutellar-axillar complex ( Fig. 6B View Fig ) with reddish-green metallic luster, setae brown and hairlike, disc flat with coarsely reticulate pattern arranged longitudinally in scutellum and transversely in axillae region; scutellum 1.58 × as long as broad. Prepectus ( Fig. 6H View Fig ) with yellowish-green metallic luster; tegula dark brown with white hair-like setae; mesopectus dark green, with sparse, long white hair-like setae anterolaterally; acropleuron dark purple with slight green metallic luster; mesopectus reticulate anterior to acropleural sulcus, acropleuron very finely longitudinally imbricate to coriaceous. Propodeum ( Figs 6I View Fig , 10F View Fig ) black with bright blue metallic luster, anterior margin very broad V-shaped; plical region comparatively long, reticulate, with patch of white setae adjacent to spiracle anteriorly and laterally, callus almost smooth and bare, with long white hair-like setae laterally. Fore wing ( Fig. 6E View Fig ) extended near apex of gaster, with costal cell dorsally bare except dark brown setae in infuscate region in front of parastigma; basal cell hyaline with white setae except for infuscate region with brown setae basally, mediocubital fold with sparse white setae; disc infuscate with dense brown setae except lightened and more hyaline apically beyond level of postmarginal vein, and with one, almost round, hyaline spot with white setae behind marginal vein; fore wing stigmal vein slightly bent to anterior margin; SMV: MV: PMV: STV = 12.0: 8.6: 5.8: 2.6. Fore leg ( Fig. 6A View Fig ) with femur dark brown to black, knee dark brown; tibia black except apex dark brown, tarsus brown; middle leg with femur black, knee brown, tibia dark brown, tarsus milky-white, spur yellowish brown, shorter than basitarsus of middle leg; hind legs with tibia black to dark brown except basal half milky-white, tibia white to light brown, with basitarsus longer than the following two tarsomeres combined.

GASTER ( Fig. 6A View Fig ). Elongate-lanceolate, longer than mesosoma, black with metallic luster, except apex of syntergum black, and ovipositor sheaths brown; syntergum tapered to rounded apex, ovipositor sheaths exserted, slightly longer than basitarsus of hind leg.

Remarks

The fore wing of females of Z. zhongi sp. nov. has a single hyaline spot with white setae behind the marginal vein ( Fig. 6E View Fig ) similar to that of females of Z. nivalinota Peng & Xiang, 2018 ( Peng et al. 2018:

fig. 26). However, females of Z. zhongi have the vertex and mesoscutum more yellowish and greenish (cf. Fig. 6B, D View Fig with Peng et al. 2018: figs 23, 25) and the concave posterior of the mesoscutum less setose ( Fig. 6B View Fig ) than females of Z. nivalinota ( Peng et al. 2018: fig. 22). Further, the ovipositor sheaths of Z. zhongi are brown, whereas they are black with the apex brown for Z. nivalinota , and the plical region of propodeum of Z. zhongi is somewhat longer ( Fig. 6I View Fig ) than that of Z. nivalinota ( Peng et al. 2018: fig. 27).

Distribution

China: Sichuan (Oriental).

Variation

The paratype is 5.4 mm in length; with only the dorsal margin of the basal half of the metatibia white, whereas the holotype ( Fig. 6A View Fig ) has the white region also across the lateral surfaces so as to extend to the ventral margin; the color of the antennal scape varies from yellowish-green to metallic blue.
