Description.

Holotype, female, length of body 6.4 mm (of fore wing 5.9 mm).

Head. Antenna with 22 segments; frons densely reticulate-punctate (Fig. 329); vertex reticulate-punctate with distinct smooth interspaces behind stemmaticum and near eyes, becoming smooth posteriorly (Fig. 330); temple rather sparsely punctate near eye and remainder smooth; head slightly narrowed behind eyes, eye in dorsal view as long as temple (Fig. 330); occipital carina narrow medio-dorsally and smooth (Fig. 330); supra-antennal elevations medium-sized (about 0.5 times as long as scapus), outer side oblique, lamelliform and largely smooth, remainder punctate; clypeus distinctly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.3 times its height (Fig. 334); mesopleuron below transverse mesopleural groove sublongitudinally rugulose anteriorly and smooth posteriorly, above groove anteriorly rugose, striate dorsally and sparsely punctate posteriorly (Fig. 334); transverse mesopleural groove narrow, shallow and sparsely crenulate; notauli narrow and smooth; middle lobe of mesoscutum coarsely densely rugose, lateral lobe rather finely and densely rugose; scutellar sulcus narrow and moderately crenulate; scutellum reticulate-rugose laterally and anteriorly, medially rather flat and anteriorly near level of mesoscutum; metanotum medially moderately convex, medially depressed and rugulose (Fig. 333); propodeum obliquely striate laterally, mainly finely rugose medially, and smooth posteriorly (Fig. 333); posterior propodeal carina rather wide lamelliform and strongly arched, foramen medially 0.8 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 1.5 times as long as vein 1-SR (Fig. 338); second submarginal cell slightly longer than third cell.

Metasoma. First tergite 0.5 times as long as apically wide, largely smooth and with distinct elliptical depression medially (Fig. 335); second-sixth tergites densely and rather finely punctate; second tergite depressed medio-basally and with superficial transverse rugose elements; first and second sternites rather sparsely and mainly finely punctate, third-fifth sternites anteriorly coarsely punctate, laterally sparser punctate; second sternite distinctly convex, without medio-apical protuberance but rather steeply depressed medio-posteriorly, and similarly setose as surroundings (Fig. 337); third sternite about 0.2 times as long as second sternite (Fig. 337); hypopygium triangular in ventral view and densely setose (Fig. 337).

Colour. Blackish brown; mandible, triangular patch along inner orbita, supra-antennal elevations, nearly entire clypeus, medium-sized stripe along outer orbita and interrupted transverse stripe on posterior vertex, anterior margin of pronotum broadly and dorsally with a narrow stripe, metanotum partly, fore coxa ventrally, middle coxa dorsally largely, trochanters largely, trochantelli, fore tibia anteriorly, base and apex of middle femur, base of hind femur, base of middle and hind tibia, pale yellow or ivory; small medial patch of vertex brown; mesosoma largely orange-brown dorsally and orange-brown laterally, but darkened ventrally; mesosternum dark brown, metasoma blackish brown but broad band on posterior margin of first tergite and of second tergite and of first sternite, broadly interrupted band on posterior margin of second sternite and sixth tergite yellowish brown; palpi yellowish brown, but labial palp partly dark brown; antenna dark brown, but scapus with yellowish ventro-apically (Fig. 331); remainder of legs dark brown; pterostigma brown, but veins, marginal cell and area below it dark brown, remainder of wing membrane subhyaline.

Variation. Length of body 5.2-13.4 mm, of fore wing 2.2-12.2 mm; antenna of ♀ with 22 (5), 23 (1), 24 (2), 25 (4) or 26 (2) segments; vertex largely smooth with sparse fine punctures behind stemmaticum to densely punctate; lateral lobe of mesoscutum longitudinally rugulose to coarsely rugose; propodeum mainly rugulose to coarsely rugose; yellow patches of inner orbita wide triangular or linear, supra-antennal elevations largely black only apically brownish to entirely yellow; transverse stripe on posterior vertex orange-yellow or reduced; pair of yellow spots on clypeus large, small or absent or clypeus entirely yellow; mesoscutum and its scutellum more or less with extensive dark brown pattern, propodeum largely orange-brown, largely dark brown except for long pale yellow stripes laterally (Fig. 356) or entirely black; mesosoma largely black laterally or dorsal half orange-brown; yellow stripe on posterior margin of second tergite narrow or interrupted medially, yellow band on posterior margin of first sternite narrow to wide, yellow posterior band of second sternite reduced to wide; legs sometimes largely dark brown; length of vein 1-M of fore wing 1.4-1.8 times as long as vein 1-SR; second metasomal tergite more or less with a shallow depression medio-basally; second sternite usually densely punctate, but sometimes sparsely so.

Male. Length of body 5.8-11.1 mm, of fore wing 5.1-10.8 mm; antenna with 22 (3), 23 (1), 24 (3) segments, tyloids linear, in specimen with 22 or 23 segments: 0.8 times as long as segment on 11 th– 14th segments and 0.2 times as long as segment on 15th segment; in specimens with 24 segments: 0.8 times as long as segment on 12 th– 14th segments and 0.2 times as long as segment on 15th segment; second sternite of ♂ partly flattened medio-posteriorly; genitalia internal; head and apex of metasoma of male darker than of female; otherwise variation as in female.

Biology.

Unknown. Collected in April–November at 900-1550 m.

Distribution.

China (Jilin, Liaoning, Shaanxi, Henan, Anhui, Zhejiang, Taiwan, Fujian, Hunan, Guangdong, Guizhou, Guangxi, Hainan); Russia (Primorskii krai); Japan; Korea ( Lelej 1995; Carmean and Kimsey 1998). Also reported from Iran, Malaysia and Indonesia ( Carmean and Kimsey 1998), but this needs reconfirmation.

Notes.

This species is variable in size, but less in colour. The form of females without apical ivory segments of the metasoma (as in males) is f. magnifica (Teranishi, 1929) and the form with the basal part of the marginal cell subhyaline is f. interrupta (Chen, 1949).
