Eye height about 1.12 × width in lateral view; distance between eyes below 3.35 × distance between eyes above; malar space 0.46 × 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: 7.2: 8.9: 10.4. Face (Figs 3C, 7C) with parascrobal region very narrow, interantennal region reticulate, scrobal depression deep and ∩-like, imbricate to reticulate, dorsal margin delimited, separated from anterior ocellus by distance equal to 0.23 × diameter of anterior ocellus; lower orbit above level of dorsal margin of torulus; lower face reticulate; vertex coriaceous posterior to ocelli, temple imbricate; frons imbricate to coriaceous. Antennal (Figs 3G, 9E–F) scape and pedicel with yellowish-purple metallic luster, 1 st to 3 rd funicular segments with slight purple luster, and other segments dark brown, setae brown; scape normal, not expanded; relative length(width) of scape = 40(10), pedicel 9.5(5), 1 st to 8 th funiculars: 6(4), 15.5(5), 19(5), 22(6.5), 15.5(7.5), 14(8), 11(8), 8(9), clava 30(10). MESOSOMA. Pronotum in dorsal view (Fig. 3B), with dark purple metallic luster, setae brown and hair-like; divided medially, pentagonal, reticulate. Mesoscutum (Figs 3B, 8K) almost flat but slightly convex anteriorly and concave posteriorly, and with lateral lobes carinate posteriorly, yellowish-green with lateral lobes slightly purple, anterior convex region with white hair-like setae (Fig. 8L), setae of posterior depressed region light brown and lanceolate (Fig. 8M), and lateral lobe with setae white and lanceolate (Fig. 8N). Scutellar-axillar complex (Fig. 3B) rusty with slight green luster, setae brown and hair-like (Figs 3B, 8O); disc flat (Figs 3B, 8K) with coarsely reticulate pattern arranged longitudinally in scutellum and transversely in axillae; scutellum 1.5× as long as broad. Prepectus (Fig. 3H) black with green to purple metallic luster; tegula with light brown hair-like setae; mesopectus dark purple, with long white hair-like setae linearly arranged along acropleural sulcus; acropleuron black with purple and green metallic luster. Mesopectus reticulate anterior to acropleural sulcus, acropleuron distinctly imbricate. Propodeum (Figs 3H–I, 10C) black with blue metallic luster, anterior margin broadly V-shaped; plical region long, reticulate, with one patch of setae anterior of spiracle, callus almost smooth and bare, but with long white hair-like setae laterally. Fore wing (Fig. 3F) with costal cell dorsally bare except for dark brown setae in infuscate region in front of parastigma; basal cell hyaline, with long brown setae, but slight infuscate at base, mediocubital fold with sparse brown setae; disc infuscate behind parastigma and stigma vein, with dense brown setae and gradually lightened distally, with one inconspicuous and irregularly shaped hyaline region behind marginal vein; fore wing extended near apex of gaster, stigmal vein distinctly bent distally to parallel anterior margin, with SMV: MV: PMV: STV = 11.0: 10.0: 7.0: 3.6. Fore leg (Fig. 3A) with knee brown, femur and tibia black, tarsus yellowish-brown; middle leg with femur black, tibia and tarsus yellowish-brown, spur black, tibial spur shorter than basitarsus; hind leg with femur black except basal part brown, knee brown, tibia yellowish brown to brown, basal half of dorsal margin milky white, tarsus brown, basitarsus longer than the following two tarsomeres combined. GASTER (Fig. 3A). Elongate-lanceolate, longer than mesosoma, dark brown to black with metallic luster, except apex of syntergum and ovipositor sheaths brown; syntergum tapered to rounded apex; ovipositor sheaths exserted for distance as long as length of basal three metatarsomeres. Remarks The fore wing color pattern of females of Z. lii sp. nov. resembles to some extent that of some females of Z. zhongi sp. nov., but they are distinguished by their ∩-like scrobal depression shape compared to the much narrower scrobal depression of females of Z. zhongi (Fig. 7F). Further, the clava of Z. lii is much longer than that of females of the other new species described in this paper, and the margin between each clava segment is S-shaped curved (Fig. 9F). Distribution China: Shaanxi (Palaearctic); Guangxi (Oriental). Variation The length of females of this new species varies from about 5.7 to 6.1 mm; one paratype has the scape slightly expanded, the relative length(width) is 36(10); hind legs of the paratype are bright orange, except the outer sides of the femora are black.Published as part of Tang, Hao, Jiang, Jingtao, Deng, Jun & Peng, Lingfei, 2022, Six new species of Zaischnopsis Ashmead (Hymenoptera: Chalcidoidea: Eupelmidae) from China based on morphological and molecular data, pp. 1-27 in European Journal of Taxonomy 847 on pages 12-15, DOI: 10.5852/ejt.2022.847.1977, http://zenodo.org/record/733087
