Mostly dark with greenish-yellow metallic luster intermixed with variably distinct purple under some angles of light, as follows: scrobal depression bluish-green (Fig. 1C), interantennal prominence purple with slight golden metallic luster (Fig. 1C), parascrobal region and lower face greenish-purple with slight golden metallic luster (Fig. 1C), frons (Fig. 1C–D) dark purple with ocellar triangle slightly green (Fig. 1D), vertex dark purple, and temple greenish-purple (Fig. 1D). Setae (Figs 1C–D, F, 7A, G) of lower face, interantennal prominence, upper part of parascrobal region, frons, vertex and occiput hair-like and brown, lower part of parascrobal region with two rows of lanceolate white setae (Fig. 8A), and setae of gena lanceolate and brown (Fig. 8D); maxillary and labial palpi black (Fig. 1C). Head in frontal view (Fig. 1C) 1.21 × as wide as high; in dorsal view (Fig. 1D) width 1.86 × length, with interocular distance 0.24 × head width and less than width of eye; in lateral view (Fig. 1F) 1.34 × as high as long. Eye height 1.32 × eye width in lateral view; distance between eyes below 2.30 × distance between eyes above; malar space 0.44 × 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: 4.0: 3.5: 2.5. Face (Figs 1C, 7A) with upper parascrobal region narrow, interantennal region finely imbricate (Fig. 8A); scrobal depression deep, reticulate-rugose, separated from anterior ocellus by distance equal to 2.30 × diameter of anterior ocellus; lower orbit above level of ventral margin of torulus; lower face coriaceous; gena longitudinally imbricate (Fig. 8D); vertex and temple transversely imbricate; frons smooth to very finely coriaceous (Fig. 7A, G). Scape and pedicel of antenna (Figs 1G, 9A–B) with greenish-yellow metallic luster, flagellum dark brown; scape normal, not expanded; relative length(width) of scape = 45(7), pedicel 10(7.5), 1 st to 8 th funiculars: 5(7), 17(6.5), 17(8), 20(8.5), 13(10.5), 11(11.5), 10(11.5), 8.5(11.5), clava 23.5(11.5).

MESOSOMA. Pronotum in dorsal view (Fig. 1B), with coppery to greenish-yellow metallic luster medially and bright purple luster laterally, setae dark brown and hair-like; divided medially, subtriangular, imbricate. Mesoscutum (Fig. 1B) almost flat but slightly convex anteriorly and concave posteriorly, and with lateral lobe carinate posteriorly, with anterior convex region and lateral lobes reddish-brown, posterior depressed region with bright blue metallic luster, setae brownish and hair-like except setae of posterior depressed region white and lanceolate. Scutellar-axillar complex (Fig. 1B) with coppery to golden luster, setae brown, disc flat with coarsely reticulate sculpture arranged longitudinally in scutellum and transversely in axillae; scutellum 1.51 × as long as broad. Prepectus (Fig. 1H) coppery-brown with metallic greenish-yellow luster; tegula (Fig. 1B) with dark brown hair-like setae; mesopectus purple with slight green metallic luster, with sparse, long white hair-like setae anteriorly, and denser patch of long white hair-like setae posteriorly underneath acropleural sulcus; acropleuron (Fig. 1H) coppery with greenish-yellow metallic luster. Mesopectus reticulate anterior to acropleural sulcus, acropleuron entirely sculptured, transversely reticulate-imbricate. Propodeum (Figs 1I, 10A) dark with blue metallic luster, anterior margin broadly V-shaped, plical region comparatively long, rugose and bare except for one patch of setae anterior to spiracle, callus smooth and bare except for long white hair-like setae laterally. Fore wing (Fig. 1E) extended to near apex of gaster, with costal cell dorsally bare except for dark setae in infuscate region in front of parastigma; basal cell hyaline but slight infuscate basally with brown setae, mediocubital fold with dark setae; disc with white setae in anterior and posterior triangular hyaline regions but infuscate with dark setae beyond level of parastigma except for region of orange brown setae within dark brown setae beyond parastigma basal to hyaline region, and gradually lightened distally to more hyaline apex; stigmal vein distinctly bent so as to parallel leading wing margin distally; SMV: MV: PMV: STV = 17: 22: 10: 5. Fore leg (Fig. 1A) with femur and tibia black, tarsus brown; middle leg with femur and tibia dark brown, tarsus brown except rows of pegs black, spur brown and shorter than basitarsus; femur of hind leg dark brown, basal one third of tibia bright yellow to white, dorsally with white hair-like setae, tarsus yellowish-brown, basitarsus as long as following two tarsomeres combined.

GASTER (Fig. 1A). Elongate-lanceolate, longer than mesosoma, dark brown with metallic luster, except apex of syntergum and apex of ovipositor sheaths brown; syntergum tapered to rounded apex; ovipositor sheaths exserted for distance equal to length of basal metatarsomere.

Remarks

There are three species from the Oriental region whose females have two hyaline spots behind the marginal vein of the fore wing, Z. biharensis (Narendram, 2004) (Narendran et al. 2007: fig. 8), Z. bathericus Narendran, 2007 (Narendran et al.: 2007: fig. 12), and Z. covid sp. nov. (Fig. 1A); the former two species are found only in India (Narendran et al. 2007). The fore wing apical angle of Z. biharensis is more acute than in the other two species (Peng et al. 2018: fig. 49), and the two hyaline spots of Z. biharensis are round, not triangular as in the other two species. The fore wing of Z. bathericus has one irregularly shaped brown spot behind the parastigma (Peng et al. 2018: fig. 50), not round as in Z. covid at the same position. The frons of most of the Oriental species of Zaischnopsis is reticulate or coriaceous, but the frons of Z. covid is almost smooth (Fig. 7A, G).

Distribution

China: Shaanxi (Palaearctic); Zhejiang (Oriental).

Variation

Females vary in length from about 3.3‒4.2 mm. Color of the pedicel variable, blue to light green; clava about 0.42‒0.70× as wide as long.
