Type material.

Holotype. China – Sichuan Prov. • ♀; Ganzizangzu Zizhizhou, Luding, Moxi; 19 Jun. 2005; light trap; (ZJUH) No. 202401057. GenBank accession no. PV 356307.

Diagnosis.

Pterostigma partly infuscated (Fig. 17 D); lateral lobes of mesoscutum comparatively matt; metanotum with three medium-sized carinae dorsally and posterior knob keeled (Fig. 17 C); anteriorly propodeum superficially sculptured between carinae (Fig. 17 C); first tergite ~ 2.3 × longer than its apical width; dorsope of first tergite small and area between dorsope much wider than dorsope (Fig. 17 K); hind tarsus mainly whitish yellow; ovipositor sheath ~ 0.24 × as long as fore wing; mandible dark brown or brown; laterope wide elliptical (Fig. 17 K).

Comparative diagnosis.

Very similar to Z. carinatus but differs mainly by the pale yellow and partly infuscated pterostigma (dark brown in Z. carinatus), the weakly curved subbasal carina of propodeum (distinctly oblique in Z. carinatus) and the dark brown mandible (yellow except dark apex in Z. carinatus).

Description.

Holotype, ♀, length of fore wing 9.5 mm, of body 9.0 mm, and antenna 1.1 × as long as fore wing.

Head. Antennal segments 46, third segment 1.1 × longer than fourth segment and third, fourth and penultimate segments 4.0 ×, 3.5 ×, and 2.0 × longer than wide, respectively; length of maxillary palp 1.7 × longer than height of head; frons smooth and behind antennal sockets impressed; POL: diameter of posterior ocellus: OOL = 10: 7: 5; vertex convex, punctulate and densely setose (Fig. 17 H); clypeus rather convex in lateral view, widely smooth, only punctate medially (Fig. 17 I); face largely punctulate and matt, it narrowed ventrally, minimum width of face 1.2 × height of face (Fig. 17 G); length of eye 2.3 × temple in dorsal view (Fig. 17 H); length of malar space 0.2 × basal width of mandible.

Mesosoma. Length of mesosoma 1.5 × its height; side of pronotum striate-rugose ventrally, rugulose-crenulate medially, smooth postero-dorsally; epicnemial area rugulose anteriorly, striate posteriorly; precoxal sulcus narrowly crenulate-rugose dorsally, coarsely reticulate-rugose ventrally; dorsal of mesopleuron densely punctate anteriorly, reticulate-rugose medially, smooth posteriorly (Fig. 17 B); mesosternum widely punctulate and comparatively matt; metapleuron mainly smooth and shiny, postero-ventrally rugose, postero-dorsally striate and smooth medially; mesoscutal lobes finely punctulate and comparatively matt; notauli anteriorly finely and narrowly crenulate; mesoscutum medio-posteriorly narrowly crenulate-rugose with a medium-sized carina; scutellar sulcus deep and rather wide with one long median carina; scutellum rather convex and widely punctulate; metanotum with small smooth knob medio-posteriorly, with three medium-sized carina in front of knob; propodeum widely reticulate-rugose, subbasal carina of propodeum irregular submedially, anterior area comparatively inconspicuously rugulose; propodeum with long straight median carina, and comparatively flat in lateral view, gradually lowered posteriorly and comparatively long (Fig. 17 C).

Wings. Fore wing (Fig. 17 D): r: 3 - SR: SR 1 = 8: 20: 101; 2 - SR: 3 - SR: r-m = 26: 24: 18; 1 - CU 1: 2 - CU 1 = 4: 75; cu-a vertical, postfurcal. Hind wing (Fig. 17 E): r absent; M + CU: 1 - M = 70: 12; 1 r-m 3.3 × 1 - M.

Legs. Hind coxa densely punctate dorsally; length of fore femur 8.3 × its width (Fig. 17 L); length of fore tibial spur 0.3 × fore basitarsus (Fig. 17 M); lengths of hind femur and basitarsus 7.4 × and 10.0 × their widths, respectively (Fig. 17 N).

Metasoma. First tergite 2.3 × longer than its apical width, its surface rugulose anteriorly, irregularly and distinctly rugose behind spiracles; dorsope narrow elliptical and comparatively small, area behind dorsope depressed (Fig. 17 K), laterope comparatively small but deep (Fig. 17 J); second tergite mainly bare, smooth; ovipositor comparatively robust basally; length of ovipositor sheath 0.24 × as long as fore wing, sheath with moderately erect and short setae (Fig. 17 F).

Colour. Antenna, mesosoma, coxae, trochanters, femora of all legs, hind tibia and metasoma largely black; head, mandible, palpi, fore and middle tibiae, and tarsus, veins C + SC + R, 1 - M and cu-a of fore wing, ovipositor sheath (except pale brown apex) mainly dark brown; hind tarsus largely whitish yellow, but its telotarsus dorsally and base of basitarsus dark brown; pterostigma pale yellowish but partly infuscated.

Distribution.

China (Sichuan).

Biology.

Unknown.

Etymology.

Named after the comparatively matt lateral lobes of the mesoscutum; impolitus is Latin for unpolished.
