Type material.
Holotype. China – Jiangxi Prov. • ♀; Shangrao, Mt. Huanggang ; 16 Aug. 2015; Ning Mao leg.; ( ZJUH) No. 202401060 . Paratype. China – Hubei Prov. • 1 ♀; Shennongjia, Muyuzhen, Tanbao River ; 21 May 2012; Lu-jing Yang leg.; ( ZJUH) No. 201203030. GenBank accession no. PV 356310 .
Diagnosis.
Pterostigma of ♀ pale brown (Fig. 21 D View Figure 21 ); length of first tergite 2.7–2.9 × its apical width (Fig. 21 I, J View Figure 21 ); first metasomal tergite conspicuously narrowed in front of dorsope (Fig. 21 J View Figure 21 ); dorsope of first tergite narrow in dorsal view and rather wide in lateral view, area between dorsope wider than dorsope and sculptured (Fig. 21 I, J View Figure 21 ); hind tarsus white or ivory medially, distinctly contrasting with apex of hind tibia (Fig. 21 A View Figure 21 ); setae of ovipositor sheath conspicuous and erect or semi-erect (Fig. 21 E View Figure 21 ); hind tarsus mainly white; ovipositor sheath ~ 0.45 × as long as fore wing.
Comparative diagnosis.
Similar to Z. chlorophthalmus but differs mainly by longer first metasomal tergite (shorter in Z. chlorophthalmus ), white hind tarsus (yellowish in Z. chlorophthalmus ) and erect or semi-erect setae of ovipositor sheath (less erect, more slanted in Z. chlorophthalmus ).
Description.
Holotype, ♀, length of fore wing 5.8 mm, of body 6.9 mm, and antenna 1.3 × as long as fore wing.
Head. Antennal segments 38, third segment 0.9 × shorter than fourth segment and third, fourth and penultimate segments 3.3 ×, 4.3 ×, and 2.0 × longer than wide, respectively; maxillary palp broken; frons smooth and behind antennal sockets impressed; POL: diameter of posterior ocellus: OOL = 7: 6: 3; vertex finely punctulate and densely setose (Fig. 21 G View Figure 21 ); clypeus convex in lateral view, weakly punctate (Fig. 21 H View Figure 21 ); face medially punctate and near antennal sockets, it narrowed ventrally, minimum width of face 1.0 × height of face (Fig. 21 F View Figure 21 ); length of eye 2.7 × temple in dorsal view (Fig. 21 G View Figure 21 ); length of malar space 0.2 × basal width of mandible.
Mesosoma. Length of mesosoma 1.7 × its height; side of pronotum largely reticulate-rugose and matt, with some striae ventrally and punctate antero-medially; epicnemial area mainly striate-rugose; precoxal sulcus coarsely reticulate-rugose dorsally, dorsal of mesopleuron largely smooth with few punctures (Fig. 21 B View Figure 21 ); mesosternum double-punctate; metapleuron coarsely irregular rugose; mesoscutal lobes densely punctate and shiny; notauli rather widely crenulate, posteriorly widely crenulate-rugose; scutellar sulcus deep and wide, with a long median carina and two indistinct short carinae; scutellum slightly convex, weakly punctate; metanotum with small posterior knob and with one rather long carina; propodeum mainly areolate, subbasal carina complete, angulate, medio-longitudinal carina complete, and mostly well developed; propodeum gradually lowered posteriorly except dorsal part in front of subbasal carina, dorsal part comparatively large and mainly densely rugose-reticulate (Fig. 21 B, C View Figure 21 ).
Wings. Fore wing (Fig. 21 D View Figure 21 ): r: 3 - SR: SR 1 = 8: 21: 99; 2 - SR: 3 - SR: r-m = 19: 21: 14; 1 - CU 1: 2 - CU 1 = 1: 30; cu-a nearly vertical, postfurcal. Hind wing (Fig. 21 D View Figure 21 ): r absent; M + CU: 1 - M = 65: 20; 1 r-m 1.7 × 1 - M.
Legs. Hind coxa largely punctate dorsally; length of fore femur 8.2 × its width (Fig. 21 K View Figure 21 ); length of fore tibial spur 0.3 × fore basitarsus (Fig. 21 L View Figure 21 ); lengths of hind femur and basitarsus 7.4 × and 11.9 × their widths, respectively (Fig. 21 M View Figure 21 ).
Metasoma. First tergite 2.9 × longer than its apical width, it narrow medially, narrow petiolate part approximately as long as remaining posterior part and posterior part comparatively narrow, its surface striate and basally rugose but shiny; dorsope elliptical and comparatively narrow, area behind dorsope depressed (Fig. 21 J View Figure 21 ), laterope large and sublateral (Fig. 21 I View Figure 21 ); second tergite mainly bare, smooth and matt; ovipositor comparatively slender basally; length of ovipositor sheath 0.45 × as long as fore wing, sheath with short semi-erect setae (Fig. 21 E View Figure 21 ).
Colour. Mesosoma, hind coxa and first metasomal tergite mainly black; head, antenna, and legs except hind leg reddish brown; hind tarsus largely white, but its telotarsus dorsally and base of basitarsus orange brown; hind tibia (except apical 1 / 6) and hind femur dark brown; veins and pterostigma pale brown; wings subhyaline with slight infuscation; apex of ovipositor sheath pale yellow.
Variation. Vein 1 r-m of hind wing 2.0–2.7 × as long as vein 1 - M; fore femur of ♀ 7.7–8.2 × longer than wide; hind femur of ♀ 7.2–7.4 × longer than wide; first metasomal tergite 2.7–2.9 × its apical width. Antennal segments of ♂ unknown.
Distribution.
China (Hubei, Jiangxi).
Biology.
Unknown.
Etymology.
Named after the conspicuously narrowed base of the first tergite, petiolatus is Latin for stalk, stem.
