Diagnosis.

Outer side of supra-antennal elevations oblique and elevations 0.4-0.5 times as long as scapus (Fig. 430); occipital carina moderately widened medio-dorsally (near weak medio-posterior depression of vertex up to 0.5 times as wide as diameter of ocellus; Fig. 430); anteriorly vertex of ♀ often partly coarsely punctate and smooth interspaces partly narrower than diameter of punctures; head posteriorly entirely black (Fig. 430); mesosoma of both sexes black dorsally and coarsely sculptured (Fig. 434); marginal cell of fore wing with brown patch (Fig. 432); second sternite of female distinctly convex, of male with shallow depressed subposterior area (Fig. 438); third sternite of male slightly convex or flat subposteriorly; third sternite 0.2-0.3 times as long as second sternite.

Description.

Holotype, male, length of body 8.7 mm (of fore wing 7.8 mm).

Head. Antenna with 23 segments with longitudinal tyloids on 10th-14th segments; frons densely coarsely punctate (interspaces less than width of punctures) and with some rugae anteriorly; vertex coarsely punctate (Fig. 430), with medium-sized setae; temple spaced punctate (Fig. 433); head gradually narrowed behind eyes, eye in dorsal view as long as temple (Fig. 430); occipital carina moderately widened medio-dorsally (near weak medio-posterior depression of vertex up to 0.5 times as wide as diameter of ocellus; Fig. 430); with few weak crenulae dorsally; supra-antennal elevations medium-sized (about 0.5 times as long as scapus) and their outer side rather steeply oblique (Fig. 430); clypeus weakly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.4 times its height (Fig. 435); transverse mesopleural groove moderately wide, deep and coarsely crenulate; mesopleuron reticulate-rugose (antero-dorsally more coarsely so), but speculum smooth and shiny; notauli moderately narrow, deep and sparsely crenulate; middle lobe of mesoscutum coarsely vermiculate rugose, lateral lobes more spaced rugose (Fig. 434); scutellar sulcus complete, medium-sized and crenulate medially and wider laterally; scutellum densely rugose, rather flat anteriorly and slightly above level of mesoscutum, but rather longitudinally depressed medially; metanotum medially distinctly convex, moderately protruding and rugose (Fig. 434); propodeum entirely vermiculate-rugose or nearly so (Fig. 434); posterior propodeal carina rather wide lamelliform and distinctly arched, foramen about 1.3 times as wide basally as high medially.

Wings. Fore wing: length of vein 1-M 1.6 times as long as vein 1-SR (Fig. 432).

Metasoma. First tergite 0.6 times as long as apically wide, largely smooth and with distinct wide depression medially (Fig. 436); second and following tergites densely superficially punctate and shiny (Fig. 436); sternites rather coarsely and densely punctate; second sternite weakly convex in lateral view (Fig. 437); third sternite 0.3 times as long as second sternite; second sternite slightly depressed medio-posteriorly (Fig. 438); third sternite flat medio-posteriorly.

Colour. Black; mandible medially, apices of fore and middle trochanters, hind trochanter and trochantellus and bases of femora largely ivory; second tergite with indistinct pair of small brownish patches posteriorly (Fig. 436); antenna (but darkened basally), palpi and tegulae mainly brown; fore tibia and tarsus, middle tibia basally brownish-yellow and remainder of legs dark brown; subapical patch of fore wing infuscate; pterostigma and veins brown, remainder of wing membrane subhyaline.

Variation. Length of body 7.0-8.7 mm, of fore wing 6.8-7.8 mm; antenna of ♂ with 22 (1), 23 (1) or 24 (1) segments, with linear tyloids on (9 th–)10th–14th(– 15th) segments; second tergite black, ivory or yellowish latero-posteriorly, propodeum coarsely to superficially sculptured.

Female. Female paratype is very similar to holotype, but brown patch of fore wing larger and darker, first metasomal tergite with pair of ivory patches apically, and second tergite with pair of large ivory patches latero-posteriorly; length of body 9.0 mm and of fore wing 8.8 mm.
