Holotype, ”, length of body 4.4 mm, of fore wing 5 mm.

Head ( figure 119 ). Remaining antennal segments 11 and 10, length of third segment 1.1 times fourth, length of third and fourth segments 3.5, 3 times their maximal width, flagellomeres with two ranks of placodes; length of eye in dorsal view twice temple; eyes glabrous; temple directly narrowed posteriorly, striate dorsally near eyes, coriaceous, shiny; OOL: diameter of ocellus: POL~8.0:4.0:5.0; frons smooth medially, shiny, punctate laterally; vertex convex, slightly punctate, flattened near stemmaticum; face convex, striate-punctate, smooth between punctures with long setae especially near eyes; clypeus convex and smooth; maxillary palp 1.5 times height of head; length of malar space 1.5 times basal width of mandible; malar suture absent; occipital flange rounded.

Mesosoma. Length of mesosoma 1.2 times its maximal height; mesopleuron sparsely punctate, smooth and shiny; precoxal sulcus complete and distinctly punctate ( figure 98 ); metapleuron sparsely punctate; mesoscutum coarsely punctate; scutellar sulcus large and smooth ( figure 25 ); scutellum convex, punctate and shiny; propodeum medially convex in lateral view, with one coarse medio-transverse rugae, with several weak rugae anteriorly, smooth posteriorly ( figure 42 ); midlongitudinal carina of propodeum weakly present anteriorly; metapleural flange short and blunt ( figure 98 ).

Wings. Fore wing: r: SR1z3-SR~9:38; 2-SR: r-m~8:5; second submarginal cell petiolate ( figure 126 ); subbasal cell glabrous anteriorly; vein 3-CU1 as long as vein CU1b. Hind wing: 2-M coloured; membrane largely glabrous basally.

Legs. Hind coxa granular, with coarse rugae dorsally; lengths of hind femur, tibia and basitarsus 5, 10 and 7 times their widths, respectively; tibial spurs 0.6 and 0.45 times basitarsus; hind tibia with five apical teeth.

Metasoma. First tergite 2.4 times longer than apically wide, smooth and shiny, apically flattened; spiracles protruding; second tergite smooth; T2 one times longer than T3; second suture obsolescent; ovipositor sheath 0.1 times fore wing length.

Colour. Brownish yellow. Hind tarsus, hind femur apico-ventrally and dorsally, stemmaticum blackish; apical patch of fore wing (half of marginal cell), stripe on outer side of scapus, basal third of inner tibial spur infuscate; humeral plate brownish; antennal segments yellow-brown, T2, basal two-thirds of posterior part of hind tibia, apical third of inner hind tibial spur, hind trochantellus, tegula yellowish.

Variation. Number of antennal segments varies between 42 and 48; T3–T7 may have brownish patches apically, hind trochantellus sometimes darker.

Remarks. Some specimens have been excluded from type-series because they differ from it in their coloration and sculpture, i.e. T2 always with brown patches medio-transversely, hind coxa with brown patch apically, and lack of coarse mediotransverse rugae on propodeum (propodeum only weakly rugulose). They may represent another species.
