Diagnosis.

Outer side of supra-antennal elevations oblique and elevations 0.1-0.4 times as long as scapus (Fig. 305); occipital carina strongly widened medio-dorsally (in female about 1.5 times as wide as diameter of ocellus), distinctly lamelliform (also dorso-laterally) and coarsely crenulate (Fig. 305), in small males often less developed but remaining lamelliform; head posteriorly entirely black (Fig. 305) or with limited yellowish or orange pattern and black behind stemmaticum, dorsally punctate with distinct interspaces (Fig. 305); mesosoma of female with limited yellowish pattern (Fig. 309) or absent in melanistic specimens (as in male); sculpture of mesosoma dorsally comparatively coarsely developed (Fig. 309); middle mesoscutal lobe similar to lateral lobes, black or yellow laterally and black medially (Fig. 309); scutellum entirely black (Fig. 309); fore wing largely subhyaline with subapical dark brown patch (Fig. 307); second sternite of female distinctly convex (Fig. 312); of male with shallow depressed subposterior area (Fig. 316); third sternite of male slightly convex or flat subposteriorly.

Description.

Holotype, female, length of body 5.9 mm (of fore wing 5.2 mm).

Head. Antenna with 22 segments; frons spaced punctate (interspaces about equal to width of punctures or less); vertex largely smooth except some superficial punctures (Fig. 305), with medium-sized setae; temple largely smooth except some sparse punctation (Fig. 308); head gradually narrowed behind eyes, eye in dorsal view 1.5 times as long as temple (Fig. 305); occipital carina strongly widened (medio-dorsally about 1.5 times as wide as posterior ocellus) and lamelliform medio-dorsally, with one strong median carina and few weak carinae laterally; supra-antennal elevations medium-sized (about 0.4 times as long as scapus) and their outer side oblique (Fig. 305); clypeus moderately concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 310); transverse mesopleural groove moderately wide, deep and sparsely crenulate; mesopleuron antero-dorsally irregularly rugose, posteriorly smooth and shiny and antero-ventrally finely irregularly rugose; notauli moderately narrow, deep and largely crenulate; middle lobe of mesoscutum coarsely transversely rugose, lateral lobes mainly finely rugose (Fig. 309); scutellar sulcus complete, medium-sized and crenulate medially and wider laterally; scutellum densely reticulate-rugose, convex anteriorly and above level of mesoscutum, but flattened medially; metanotum medially slightly convex, not protruding and largely obliquely rugose (Fig. 309); propodeum largely longitudinally rugose or nearly so (Fig. 309); posterior propodeal carina rather wide lamelliform and distinctly arched (foramen about 1.1 times as wide as high medially).

Wings. Fore wing: length of vein 1-M 1.4 times as long as vein 1-SR (Fig. 307).

Metasoma. First tergite 0.6 times as long as apically wide, smooth and with distinct elliptical depression medially (Fig. 311); second tergite largely smooth and shiny, other tergites superficially punctate (Fig. 311); sternites largely smooth except spaced superficial punctures; second sternite distinctly curved in lateral view (Fig. 312); third sternite about 0.2 times as long as second sternite (Fig. 313); hypopygium triangular in ventral view.

Colour. Black; apex of scapus, inner and outer orbita narrowly, middle mesoscutal lobe antero-laterally, small anterior spot of lateral lobe, metanotum with small lateral spot, first tergite with faint patch postero-laterally and second tergite with large postero-lateral patch yellow (Fig. 311); apical 0.4 of antenna, tegulae, remainder of scapus and basally palpi dark brown, remainder of antenna and palpi apically brown; mandible dark brown but subbasally and near base of teeth brown; apex of trochanters narrowly and trochantelli largely pale yellow and remainder dark brown; fore femur apically and most of tibia yellowish brown, remainder of fore leg dark brown; apex of metasoma narrowly brown; apical patch of fore wing, pterostigma and veins dark brown, remainder of wing membrane subhyaline.

Variation. Length of body 4.9-10.4 mm, of fore wing 4.7-9.0 mm; antenna of ♀ with 21 (1), 22 (10), 23 (6) or 24 (2) segments; yellow patches of inner orbita wide triangular or linear, mandible brown to largely yellow; lateral brownish patch of vertex present or absent; patch lateral mesoscutal lobes postero-laterally and axilla black or yellow; metanotum black or yellow medially and its lateral patch narrow or wide; propodeum black or with pair of large yellow patches; tegulae dark brown, brown or yellow; first and second sternites latero-posteriorly black or orange-brown; only first and second tergites or all tergites yellow or orange-brown latero-posteriorly, patches sometimes connected except for a small brown triangle; second tergite largely smooth to largely moderately densely punctate; vertex largely smooth except some superficial punctures to largely coarsely punctate; length of vein 1-M of fore wing 1.3-1.6 times as long as vein 1-SR; width of depression in front of occipital carina medio-dorsally 1.0-1.5 times width of posterior ocellus and crenulation varies from strong to weak.

Male. Length of body 5.0-8.4 mm, of fore wing 4.2-7.7 mm; antenna with 21 (1), 22 (16), 23 (10) or 24 (3) segments, tyloids linear, 0.7 times as long as segment on 11 th– 14th segments and about half as long on 10th and 15th segments with a remnant on 16th segment; genitalia internal, sometimes extruded (Fig. 316); in general males are darker than females: head entirely black or orbita narrowly yellow and mesosoma black or pronotum dorsally slightly yellow; tegulae brown or yellow; metasoma coloured as holotype or darker; sculpture varies as in females, but in general less strongly developed.

Biology.

Unknown. Collected in June–September at 1200-2350 m.

Distribution.

China (Gansu, Ningxia, Shaanxi, Henan, Zhejiang, Fujian, Sichuan, Yunnan).

Etymology.
