Type material.

Holotype. China – Shaanxi Prov. • ♀; Xunyangba, Ningshan; 33.55°N, 108.55°E; alt. 1481 m; 20 May – 23 Jun. 2016; Jiang-li Tan, Qing-qing Tan leg.; Black Malaise trap; (ZJUH) No. 202315004 . Paratype. China – Shaanxi Prov. • 1 ♀; same data as for holotype; (NWU) No. 202315003 .

Diagnosis.

Malar space 0.4 × as long as basal width of mandible; pterostigma of ♀ dark brown (Fig. 16 D); ventral 1 / 2 of temple yellowish, strongly contrasting with blackish mesosoma (Fig. 16 G, C); face 1.4 × wider than high (Fig. 16 F); first tergite ~ 2.4 × longer than its apical width; dorsope of first tergite small and area between dorsope much wider than dorsope (Fig. 16 J); hind tarsus mainly white; ovipositor sheath ~ 0.45 × as long as fore wing.

Comparative diagnosis.

Similar to Z. petiolatus but differs mainly by longer malar space (shorter in Z. petiolatus), wide face (narrow in Z. petiolatus) and dark brown pterostigma (pale brown in Z. petiolatus).

Description.

Holotype, ♀, length of fore wing 7.2 mm, of body 8.4 mm.

Head. Antenna incomplete, third segment nearly as long as fourth segment and third and fourth segments 3.0 × and 3.1 × longer than wide, respectively; length of maxillary palp 1.4 × longer than height of head; frons partly rugulose and behind antennal sockets impressed; POL: diameter of posterior ocellus: OOL = 10: 8: 11; vertex finely punctulate and densely setose; clypeus strongly convex in lateral view, weakly punctate (Fig. 16 H); face almost smooth, widened ventrally, minimum width of face 1.4 × height of face (Fig. 16 F); length of eye 2.0 × temple in dorsal view (Fig. 16 G); length of malar space 0.4 × basal width of mandible.

Mesosoma. Length of mesosoma 1.7 × its height; side of pronotum largely reticulate-crenulate and matt, with some striae ventrally; epicnemial area mainly reticulate-rugose; precoxal sulcus comparatively carinate dorsally, largely reticulate-rugose; remainder of mesopleuron smooth with few sculptured (Fig. 16 B); mesosternum coarsely punctate; metapleuron narrowly smooth anteriorly, largely rugose-reticulate; mesoscutal lobes punctate and shiny; notauli rather widely crenulate, mesoscutum medio-posteriorly widely crenulate-rugose. scutellar sulcus deep and wide, with a long median carina; scutellum slightly convex, smooth; metanotum with small posterior knob and with three rather long carinae; propodeum mainly rugulose, subbasal carina of propodeum mainly straight to curved posteriad; medio-longitudinal carina complete, and mostly well developed; in lateral view propodeum gradually lowered posteriorly except for dorsal part in front of subbasal carina and this dorsal part comparatively large (Fig. 16 B, C).

Wings. Fore wing (Fig. 16 D): r: 3 - SR: SR 1 = 7: 15: 91; 2 - SR: 3 - SR: r-m = 27: 22: 11; 1 - CU 1: 2 - CU 1 = 5: 70; cu-a nearly vertical, postfurcal. Hind wing: r absent; M + CU: 1 - M = 82: 20; 1 r-m 2.0 × 1 - M.

Legs. Hind coxa widely punctate dorsally; length of fore femur 7.4 × its width (Fig. 16 K); length of fore tibial spur 0.3 × fore basitarsus (Fig. 16 L); lengths of hind femur and basitarsus 7.0 × and 12.1 × their widths, respectively (Fig. 16 M).

Metasoma. First tergite 2.4 × longer than its apical width, it narrow medially, its surface finely strigate basally and shiny; dorsope elliptical and comparatively small, area behind dorsope depressed (Fig. 16 J), laterope small and sublateral (Fig. 16 I); second tergite mainly bare, smooth and shiny; ovipositor comparatively robust basally; length of ovipositor sheath 0.45 × as long as fore wing, sheath with long semi-erect setae (Fig. 16 E).

Colour. Mesosoma, hind coxa, hind tibia (except apical 1 / 6) and part of hind femur and apical 1 / 2 of first metasomal tergite, ovipositor sheath (but apex pale brown) mainly black; head, face, legs except hind leg yellowish; hind tarsus largely white, but its telotarsus dorsally and base of basitarsus brownish yellow; pterostigma dark brown; wings subhyaline with slight infuscation.

Variation. Vein 1 r-m of hind wing 2.0–2.3 × as long as vein 1 - M; fore femur of ♀ 7.4–7.6 × longer than wide; hind femur of ♀ 6.8–7.0 × longer than wide;

Distribution.

China (Shaanxi).

Biology.

Unknown.

Etymology.

Named after the dark mesosoma, strongly contrasting with the ventral half of the yellowish temple; fuscatus is Latin for darkened.
