Type material.

Holotype. China – Sichuan Prov. • ♀; Ganzizangzu Zizhizhou, Luding, Gongkou; 27 Jul. 2005; Jiang-li Tan leg.; (ZJUH) No. 202401049 . Paratypes. China – Sichuan Prov. • 2 ♀♀; Ganzizangzu Zizhizhou, Luding, Moxi; 19 Jun. 2005; light trap; (ZJUH) Nos. 202401087, 202401088. GenBank accession no. PV 356299, PV 356326, PV 356327 .

Diagnosis.

Propodeum depressed posteriorly in lateral view (Fig. 24 B); mandible blackish (Fig. 24 I); first tergite more widened posteriorly (compared to its minimum width: Fig. 24 K); pterostigma pale yellowish, at most posterior rim slightly infuscated (Fig. 24 D); hind tarsus whitish yellow; laterope narrow elliptical (Fig. 24 K); lateral lobe of mesoscutum shiny; metanotum with 2 long carinae; mesoscutum medio-posteriorly with medium-sized carina (Fig. 24 C); first tergite robust posteriorly and anteriorly comparatively abruptly narrowed (Fig. 24 K), ~ 2.2–2.3 × longer than its apical width; dorsope of first tergite long and moderately wide, area between dorsope distinctly wider than dorsope (Fig. 24 K); ovipositor sheath ~ 0.19 × as long as fore wing.

Comparative diagnosis.

Very similar to Z. impolitus but differs mainly by pale yellowish pterostigma (partly infuscated in Z. impolitus), anteriorly propodeum remotely sculptured between carinae (superficially sculptured in Z. impolitus) and metanotum with two rather long carinae dorsally and without knob posteriorly (with three medium-sized carinae dorsally and knob keeled posteriorly in Z. impolitus).

Description.

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

Head. Antennal segments 45, third segment 1.1 × longer than fourth segment and third, fourth and penultimate segments 3.8 ×, 3.2 ×, 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 = 8: 8: 5; vertex convex, punctulate and densely setose; clypeus rather convex in lateral view, widely punctate dorsally, smooth ventrally (Fig. 24 I); face largely smooth, rugulose near antennal sockets and eyes, and narrowed ventrally (Fig. 24 G), minimum width of face 1.2 × height of face; length of eye 2.1 × temple in dorsal view (Fig. 24 H); length of malar space 0.3 × basal width of mandible.

Mesosoma. Length of mesosoma 1.6 × its height; side of pronotum striate-rugose ventrally, reticulate-rugose medially, smooth postero-dorsally; epicnemial area largely rugulose; precoxal sulcus widely crenulate-rugulose dorsally, narrowly punctulate ventrally, posteriorly narrowly smooth; dorsal of mesopleuron largely smooth and shiny, finely punctulate (Fig. 24 B); mesosternum finely punctulate; metapleuron mainly smooth and shiny anteriorly, postero-ventrally rugose, postero-dorsally smooth; mesoscutal lobes widely punctulate and comparatively shiny; notauli anteriorly finely and narrowly crenulate, mesoscutum medio-posteriorly narrowly crenulate-rugose and with a long carina; scutellar sulcus deep and rather wide with one long obvious median carina; scutellum rather convex and finely punctulate; metanotum with small smooth knob medio-posteriorly, with two long carinae in front of knob; propodeum widely reticulate-rugose, subbasal carina of propodeum absent or fragmented submedially, anterior part of propodeum rather smooth anteriorly; propodeum with long straight median carina, and comparatively flat in lateral view and comparatively long; propodeum gradually lowered posteriorly, and posterior part not distinctly separated from antero-dorsal part distinctly (Fig. 24 B, C).

Wings. Fore wing (Fig. 24 D): r: 3 - SR: SR 1 = 9: 23: 120; 2 - SR: 3 - SR: r-m = 26: 23: 17; 1 - CU 1: 2 - CU 1 = 3: 86; cu-a vertical, postfurcal. Hind wing (Fig. 24 D): r absent; M + CU: 1 - M = 80: 12; 1 r-m 3.4 × 1 - M.

Legs. Hind coxa densely punctate dorsally; length of fore femur 8.2 × its width (Fig. 24 L); length of fore tibial spur 0.3 × fore basitarsus (Fig. 24 M); lengths of hind femur and basitarsus 7.5 × and 9.0 × their widths, respectively (Fig. 24 F).

Metasoma. First tergite 2.2 × longer than its apical width, its surface largely irregularly rugulose, only narrowly smooth posteriorly near second tergite; dorsope narrow elliptical and comparatively small, area behind dorsope depressed (Fig. 24 K), laterope comparatively small but deep (Fig. 24 J); second tergite mainly bare, smooth; ovipositor comparatively robust basally; length of ovipositor sheath 0.19 × length of fore wing, sheath with short semi-erect setae (Fig. 24 E).

Colour. Antenna, vertex, mesosoma, coxae, trochanters of all legs, hind femur, hind tibia (except dark brown basal of 1 / 3), and metasoma largely black; head, mandible, fore and middle femora reddish brown; fore and middle tibias and tarsus yellowish brown; vein C + SC + R, vein 1 - M and vein cu-a of fore wing, ovipositor sheath (except pale yellowish apex) mainly dark brown; hind tarsus largely whitish yellow, but its telotarsus dorsally and base of basitarsus dark brown; palpi and pterostigma pale yellowish.

Variation. Vein 1 r-m of hind wing 3.3–4.0 × as long as vein 1 - M; fore femur of ♀ 7.9–8.3 × longer than wide; hind femur of ♀ 7.0–7.5 × longer than wide; first metasomal tergite 2.2–2.3 × its apical width.

Distribution.

China (Sichuan).

Biology.

Unknown.

Etymology.

Named after the very finely and densely rugulose precoxal sulcus; rugulosus is Latin for finely creased.
