Type material.

Holotype. China – Sichuan Prov. • ♀; Ganzizangzu Zizhizhou, Luding, Moxi; 18 Jun. 2005; Jing-xian Liu leg.; (ZJUH) No. 202401086. GenBank accession no. PV 356325.

Diagnosis.

Pterostigma dark brown or brown (Fig. 5 D) and mandible yellow (except dark apex) (Fig. 5 F); subbasal carina of propodeum distinctly oblique medially (Fig. 5 C); propodeum depressed posteriorly and slightly shorter in lateral view (Fig. 5 B); mesoscutum medio-posteriorly with short longitudinal carina (Fig. 5 C); first tergite ~ 2.3 × longer than its apical width; dorsope of first tergite rather small and space between dorsope much wider than dorsope and sculptured (Fig. 5 J); hind tarsus mainly white; ovipositor sheath ~ 0.23 × as long as fore wing; vein r of fore wing oblique.

Comparative diagnosis.

Very similar to Z. rugulosus but differs mainly by the blackish brown pterostigma (pale yellow in Z. rugulosus), the distinctly oblique subbasal carina of propodeum (transverse in Z. rugulosus) and the short longitudinal carina on the mesoscutum (long in Z. rugulosus).

Description.

Holotype, ♀, length of fore wing 6.9 mm, of body 6.7 mm, and antenna 1.1 × as long as fore wing.

Head. Antennal segments 42, third segment nearly as long as fourth segment and third, fourth and penultimate segments 2.8 ×, 2.7 ×, and 2.0 × 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 = 8: 6: 6; vertex less convex, smooth and densely setose (Fig. 5 G); clypeus rather convex in lateral view, widely smooth, only punctate medially; face largely crenulate and matt, widened ventrally, minimum width of face 1.2 × height of face (Fig. 5 F); length of eye 1.8 × temple in dorsal view (Fig. 5 G); length of malar space 0.3 × basal width of mandible.

Mesosoma. Length of mesosoma 1.6 × its height; side of pronotum striate ventrally, rugulose-crenulate medially, smooth postero-dorsally; epicnemial area smooth; precoxal sulcus densely rugose, only posteriorly narrowly smooth; dorsal of mesopleuron largely smooth with indistinct punctulation (Fig. 5 B); mesosternum finely punctulate dorsally; metapleuron mainly smooth and matt, ventrally rugose; mesoscutal lobes finely punctulate and shiny; notauli anteriorly finely and narrowly crenulate, posteriorly narrowly crenulate-rugose; mesoscutum medio-posteriorly with a short carina; scutellar sulcus deep and rather wide with one long obvious median carina; scutellum rather convex and punctulate; metanotum with small and smooth knob medio-posteriorly, one short media carina on knob, but without median carina in front of it; propodeum widely reticulate-rugose, subbasal carina of propodeum straight and oblique medially, comparatively inconspicuously rugulose anteriorly; propodeum with long straight median carina, rather convex and short in lateral view; in lateral view propodeum gradually lowered posteriorly, posterior of it not separated from antero-dorsal part distinctly (Fig. 5 B, C).

Wings. Fore wing (Fig. 5 D): r: 3 - SR: SR 1 = 10: 20: 100; 2 - SR: 3 - SR: r-m = 26: 25: 17; 1 - CU 1: 2 - CU 1 = 3: 75; cu-a vertical, postfurcal. Hind wing (Fig. 5 D): r absent; M + CU: 1 - M = 75: 15; 1 r-m 2.6 × 1 - M.

Legs. Hind coxa densely punctate dorsally; length of fore femur 7.6 × its width (Fig. 5 K); length of fore tibial spur 0.3 × fore basitarsus (Fig. 5 M); lengths of hind femur and basitarsus 7.2 × and 9.2 × their widths, respectively (Fig. 5 L).

Metasoma. First tergite 2.3 × longer than its apical width, its surface irregularly rugulose; dorsope elliptical and comparatively small (Fig. 5 J), laterope comparatively small and very narrow (Fig. 5 I); second tergite mainly bare and smooth; ovipositor comparatively slender basally; length of ovipositor sheath 0.23 × as long as fore wing, sheath with rather slanted and long setae (Fig. 5 E).

Colour. Antenna, mesosoma, coxae of all legs, hind leg (except hind tarsus) and metasoma, largely black; head, fore and middle legs mainly reddish brown; hind tibia largely black but its apical 1 / 5 reddish brown; hind tarsus largely whitish yellow, but its telotarsi dorsally and base of basitarsus brown; palpi pale yellow; vein C + SC + R of fore wings, pterostigma and ovipositor sheath (except pale brown apex) dark brown.

Distribution.

China (Sichuan).

Biology.

Unknown.

Etymology.

Named after the long straight median carina of the propodeum; carinatus is Latin for ridge.
