Type material.

Holotype. China – Ningxia Huizu Zizhiqu • ♀; Mt. Liupan, Heshangpu Forest Farm; 25 Jun. 2008; Jing-xian Liu leg.; (ZJUH) No. 202401065 . Paratype. China – Ningxia Huizu Zizhiqu • 1 ♀; Liupan, Fengtai Forest Farm; 27 Jun. 2008; Jing-xian Liu leg.; (ZJUH) No. 202401064. GenBank accession no. PV 356314, PV 356315 .

Diagnosis.

Marginal cell of hind wing strongly widened apically (Fig. 18 E); densely sculptured area of precoxal sulcus medium-sized medially (Fig. 18 B); malar space ~ 0.2 × as long as basal width of mandible; metanotum with enlarged smooth knob medio-posteriorly and median carina in front of it short (Fig. 18 C); first tergite 2.1–2.2 × longer than its apical width; dorsope of first tergite large and area between dorsope approximately as wide as dorsope and nearly smooth (Fig. 18 K); hind tarsus yellowish; ovipositor sheath ~ 0.26 × as long as fore wing; vein cu-a of fore wing slightly oblique (Fig. 18 D).

Comparative diagnosis.

Similar to Z. caligatus but differs mainly by the strongly widened marginal cell of hind wing (slightly widened in Z. caligatus), the short malar space (long in Z. caligatus) and the enlarged smooth knob of metanotum (small in Z. caligatus).

Description.

Holotype, ♀, length of fore wing 6.1 mm, of body 6.3 mm, and antenna nearly as long as fore wing.

Head. Antennal segments 38, third segment 0.9 × shorter than fourth segment and third, fourth and penultimate segments 3.4 ×, 3.7 ×, and 1.8 × longer than wide, respectively; length of maxillary palp 1.3 × longer than height of head; frons smooth and behind antennal sockets impressed; POL: diameter of posterior ocellus: OOL = 9: 5: 3; vertex finely punctulate and densely setose (Fig. 18 H); clypeus convex in lateral view, largely smooth (Fig. 18 I); face widely smooth but punctulate near antennal sockets, it slightly narrowed ventrally (Fig. 18 G), minimum width of face 1.3 × height of face; length of eye 2.5 × temple in dorsal view (Fig. 18 H); length of malar space 0.2 × basal width of mandible.

Mesosoma. Length of mesosoma 1.6 × its height; side of pronotum largely smooth, with some striae medially and ventrally; epicnemial area widely smooth, narrowly rugulose postero-dorsally; precoxal sulcus finely rugulose anteriorly, and narrowly short striate posteriorly; dorsal of mesopleuron widely smooth and shiny (Fig. 18 B); mesosternum smooth and shiny; metapleuron smooth medially but striate-rugose anteriorly and posteriorly; mesoscutal lobes finely punctulate and shiny; notauli indistinctly crenulate; scutellar sulcus shallow, with a long median carina and four short indistinctly ones; scutellum slightly convex, weakly punctate; metanotum with enlarged smooth knob medio-posteriorly and short median carina in front of it; propodeum remotely reticulate, without subbasal transverse carina and medio-longitudinal carina; propodeum gradually lowered posteriorly, posterior part not distinctly separated from antero-dorsal part distinctly (Fig. 18 B, C).

Wings. Fore wing (Fig. 18 D): r: 3 - SR: SR 1 = 5: 11: 50; 2 - SR: 3 - SR: r-m = 10: 11: 8; 1 - CU 1: 2 - CU 1 = 5: 52; cu-a oblique, postfurcal. Hind wing (Fig. 18 E): r absent; M + CU: 1 - M = 85: 15; 1 r-m 3.0 × 1 - M.

Legs. Hind coxa largely smooth and shiny dorsally; length of fore femur 7.4 × its width (Fig. 18 L); length of fore tibial spur 0.3 × fore basitarsus (Fig. 18 N); lengths of hind femur and basitarsus 7.0 × and 13.3 × their widths, respectively (Fig. 18 M).

Metasoma. First tergite 2.2 × longer than its apical width, it narrow the apical 1 / 3, its surface indistinctly striate and shiny; dorsope elliptical, comparatively large, area behind depressed (Fig. 18 K), laterope comparatively large and deep (Fig. 18 J); second tergite mainly bare, smooth and glossy; ovipositor comparatively slender basally; length of ovipositor sheath 0.26 × length of fore wing, sheath with short semi-erect setae (Fig. 18 F).

Colour. Mainly yellowish; apical 1 / 2 of antenna and ovipositor sheath brown; veins and pterostigma pale yellow.

Variation. Vein 1 r-m of hind wing 2.0–3.0 × as long as vein 1 - M; fore femur of ♀ 7.4–8.0 × longer than wide; hind femur of ♀ 6.0–7.0 × longer than wide; first metasomal tergite 2.2–2.3 × its apical width. Antennal segments of ♂ unknown.

Distribution.

China (Ningxia).

Biology.

Unknown.

Etymology.

Named after the oblique vein cu-a of the fore wing; clino is Latin for slope.
