Diagnosis
Head with dorsal margin of scrobal depression not delimited, ventral part of scrobal depression smooth (Fig. 7B); antennal clava about 2.6× as long as wide (Fig. 2G). Legs with mesotibia and metatibia yellowish brown (Fig. 2A). Fore wing disc infuscate with light brown setae beyond level of parastigma and gradually lightened distally, without hyaline region with white setae behind marginal vein (Fig. 2E). Propodeum with anterior margin broad U-shaped; plical region short (Figs 2I, 10B).
Etymology
The species name is a combination of the Latin words ‘ fusca ’, ‘dark colored’, and ‘ lividus ’, ‘bluish’, in reference to the dark blue mesoscutum.

Description
Female
LENGTH. About 4.5 mm.
HEAD (Fig. 2C–D, F). With blue metallic luster intermixed with variably distinct purple and green lusters under some angles of light, as follows: scrobal depression dark blue (Fig. 2C), interantennal prominence blue or with slight metallic purple luster (Fig. 2C), parascrobal region and lower face greenish-purple with golden metallic luster (Fig. 2C), frons dark purple, vertex and temple dark purple with slight green luster (Fig. 2D). Setae of face (Fig. 7B), gena (Fig. 8E–F), interantennal prominence and occiput hairlike and brown, parascrobal region with two rows of hair-like brown setae (Fig. 7B); maxillary and labial palpi dark brown (Fig. 2C). Head in frontal view 1.25 × as wide as high; in dorsal view width 1.65 × length, with interocular distance 0.25 × head width and less than width of eye; in lateral view 1.38 × as high as long. Eye height 1.05 × eye width in lateral view; distance between eyes below 2.84 × distance between eyes above; malar space 0.53 × eye height; distance between toruli greater than distance between torulus and clypeal margin, and similar to distance between torulus and orbit. OOL: POL: LOL: MPOD = 1.0: 5.0: 4.6: 4.0. Face (Figs 2C, 7B) with parascrobal region very narrow, interantennal region longitudinally reticulate, scrobal depression deep and ∩-like, smooth ventrally and finely imbricate dorsally, dorsal margin not delimited; lower orbit above level of ventral margin of torulus; lower face alutaceous-imbricate to coriaceous (Fig. 7B); vertex and temple transversely imbricate; frons imbricate to coriaceous. Antennal (Figs 2G, 9C–D) scape and pedicel with bluish-green metallic luster, 1 st to 4 th funicular segments with greenish-yellow to rusty metallic luster, with light brown to white setae, 5 th to 8 th funicular segments dark brown, with dark brown setae; scape normal, not expanded; relative length(width) of scape = 38(6), pedicel 12(4.5), 1 st to 8 th funiculars: 5(4), 14.5(4), 14.5(5), 16(5.5), 12.5(6), 12.5(7), 11.5(7), 9(7), clava 22(8.5).
MESOSOMA. Pronotum in dorsal view (Fig. 2B), dark purple with metallic luster; setae dark brown and hair-like; divided medially, subtriangular, imbricate. Mesoscutum (Fig. 2B) almost flat but slightly convex anteriorly, and with lateral lobes carinate posteriorly, metallic blue with middle part of anterior convex region and lateral lobes slightly yellowish-green, setae of anterior convex region and lateral lobes brownish and hair-like, setae of posterior depressed region and lower part of lateral lobes white and lanceolate. Scutellar-axillar complex coppery except lateral surface of scutellum somewhat blue, setae brown, disc of scutellar-axillar complex (Fig. 2B) flat with coarsely reticulate pattern arranged longitudinally in scutellum and transversely in axillae; scutellum 1.38 × as long as broad. Prepectus (Fig. 2H) dark brown with slight yellow luster, tegula with dark brown hair-like setae; mesopectus greenish-purple, with long white hair-like setae linearly arranged along acropleural sulcus; acropleuron dark purple with green metallic luster. Mesopectus reticulate anterior to acropleural sulcus, acropleuron with distinctly transverse reticulate-imbricate sculpture. Propodeum (Figs 2H–I, 10B) dark with yellowish-blue metallic luster, anterior margin broad U-shaped; plical region short, reticulate-rugose, with three setae near inner margin of spiracle and one patch of setae anterior of spiracle, callus coriaceous and bare, with long white hair-like setae laterally. Fore wing (Fig. 2E) with costal cell dorsally bare except for dark setae in infuscate region in front of parastigma; basal cell hyaline with light brown setae, mediocubital fold with sparse, light brown setae; disc with setae light brown and gradually lightened distally, without hyaline region with white behind marginal vein; fore wing extended near apex of gaster, stigmal vein slightly bent distally; SMV: MV: PMV: STV = 17.5: 22.5: 16.5: 7. Fore leg (Fig. 2A) with femur black, knee brown, tibia with basal half dark brown and apical half yellowish-brown, tarsus yellowish-brown; middle leg with femora brown, tibia yellowish-brown, tarsus white to light brown except rows of pegs dark brown and spur brown, mesotibial spur shorter than basitarsus; femur of hind leg dark with green metallic luster, knee brown, tibia yellowish-brown, tarsus yellowish-brown, basitarsus as long as following two tarsomeres combined.
GASTER (Fig. 2A). 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 slightly shorter than length of basal metatarsomere.
Remarks
The fore wing of females Z. fuscolivida sp. nov. lack any hyaline spot or band, which distinguishes them from those of other species of Zaischnopsis from China. Females do resemble Z. locustae (Girault, 1919), recorded only from Java, Indonesia, but females of Z. locustae have white setae on the vertex and temple (Peng et al. 2018: figs 53, 56) versus brown for Z. fuscolivida (Fig. 2C), and the metatibia is dark brown except the basal half of the dorsal margin which is white (Peng et al. 2018: fig. 57) versus yellowish-brown (Fig. 2A).
Distribution
China: Shaanxi (Palaearctic); Zhejiang (Oriental).
Variation
The length of the females varies from about 4.3 to 5.8 mm. The color of the pedicel is variable, blue to yellowish-green; the shape of the posterior ocellus is sometimes rhomboid or oval, the OOL varies from 0.14 to 0.31 × as wide as MPOD.
