Type material.

Holotype. China – Sichuan Prov. • ♀; Ganzizangzu Zizhizhou, Luding, Moxi; 19 Jun. 2005; light trap; (ZJUH) No. 202401058 . Paratype. China – Qinghai Prov. • 1 ♀; Yushuzangzu Zizhizhou, Nangqian; 25 Jun. 2005; Jiang-li Tan leg.; (ZJUH) No. 202401048. GenBank accession no. PV 356308, PV 356298 .

Diagnosis.

Eyes more protruding and temples more directly narrowed in dorsal view (Fig. 11 H); vein m-cu of fore wing slightly curved (Fig. 11 D); anterior tentorial pits close to eyes (Fig. 11 G) second tergite black; mandible yellowish (except dark apex) (Fig. 11 G); pterostigma pale yellowish (Fig. 11 D); first tergite ~ 2.3 × longer than its apical width; dorsope of first tergite small and space between dorsope much wider than dorsope and sculptured (Fig. 11 K); hind tarsus mainly white; ovipositor sheath ~ 0.24 × as long as fore wing.

Comparative diagnosis.

Very similar to Z. shaanxiensis but differs mainly by the more protruding eyes (less protruding in Z. shaanxiensis), curved vein m-cu of fore wing (straight in Z. shaanxiensis) and anterior tentorial pits close to eyes (distinctly removed from eyes in Z. shaanxiensis).

Description.

Holotype, ♀, length of fore wing 8.0 mm, of body 8.0 mm, and antenna 1.2 × as long as fore wing.

Head. Antennal segments 42, third segment nearly as long as fourth segment and third, fourth and penultimate segments 3.3 ×, 3.1 ×, and 1.8 × longer than wide, respectively; length of maxillary palp 1.5 × longer than height of head; frons smooth and behind antennal sockets impressed; POL: diameter of posterior ocellus: OOL = 12: 10: 5; vertex convex, punctulate and densely setose (Fig. 11 H); clypeus rather convex in lateral view, widely smooth, punctate medially (Fig. 11 I); face largely smooth, it widened ventrally, minimum width of face 1.1 × height of face (Fig. 11 G); length of eye 2.2 × temple in dorsal view (Fig. 11 H); length of malar space 0.3 × basal width of mandible.

Mesosoma. Length of mesosoma 1.6 × its height; side of pronotum reticulate-rugulose ventrally and posteriorly, rugose anteriorly; epicnemial area reticulate-rugulose; precoxal sulcus densely strigate-rugose dorsally, narrowly reticulate-punctate antero-ventrally; dorsal of mesopleuron largely smooth (Fig. 11 B); mesosternum almost smooth, finely punctulate; metapleuron smooth anteriorly, and widely scabrous posteriorly; mesoscutal lobes finely punctulate and shiny; notauli anteriorly finely and narrowly crenulate, mesoscutum medio-posteriorly widely crenulate-rugose and with a long carina; scutellar sulcus deep and rather narrow with one long obvious median carina; scutellum rather convex and finely punctulate; metanotum with small smooth knob medio-posteriorly, with one short media carina on knob, with two weakly converging long carinae medially; propodeum widely reticulate-rugose, subbasal transverse carina of propodeum mainly straight to curved posteriad, comparatively finely punctulate anteriorly; in lateral view propodeum gradually lowered posteriorly (Fig. 11 B, C).

Wings. Fore wing (Fig. 11 D): r: 3 - SR: SR 1 = 9: 20: 105; 2 - SR: 3 - SR: r-m = 23: 20: 14; 1 - CU 1: 2 - CU 1 = 3: 60; cu-a vertical, postfurcal. Hind wing (Fig. 11 E): r absent; M + CU: 1 - M = 62: 12; 1 r-m 3.3 × 1 - M; marginal cell strongly widened apically (Fig. 11 E).

Legs. Hind coxa densely punctate dorsally; length of fore femur 8.0 × its width (Fig. 11 L); length of fore tibial spur 0.3 × fore basitarsus (Fig. 11 M); lengths of hind femur and basitarsus 7.3 × and 8.5 × their widths, respectively (Fig. 11 N).

Metasoma. First tergite 2.3 × longer than its apical width, its surface rugulose; dorsope comparatively small and narrow, area in front of dorsope depressed (Fig. 11 K), laterope comparatively narrow (Fig. 11 J); second tergite mainly bare, smooth; ovipositor comparatively robust basally; length of ovipositor sheath 0.24 × length of fore wing, sheath with moderately erect and short setae (Fig. 11 F).

Colour. Mesosoma, metasoma, coxae and trochanters of middle and hind legs, hind femur, hind tibia (except dark brown apical 1 / 3) black; head, fore and middle legs mainly brownish yellow; hind tarsus white; antenna and veins C + SC + R, 1 - M and cu-a of fore wing dark brown; palpi, pterostigma and other veins pale yellow; and ovipositor sheath (except pale whitish apex) brown.

Variation. Vein 1 r-m of hind wing 3.3–3.6 × as long as vein 1 - M; fore femur of ♀ 8.0–8.5 × longer than wide; hind femur of ♀ 7.0–7.3 × longer than wide; first metasomal tergite 2.3–2.5 × its apical width.

Distribution.

China (Qinghai, Sichuan).

Biology.

Unknown.

Etymology.

Named after the slightly curved vein m-cu of the fore wing; curvus and nervus is Latin respectively for curved and vein.
