Face 0.38–0.4 × as long as minimum width; slightly convex medially; matt; densely punctate medially; punctures partly united into groove-like foveola medially. Frons weakly concave above antennal sockets; punctate except for narrow smooth area above each antennal socket. POL 1.6–2.0 × as OD. OOL 1.6–2.1 × as OD. Gena and occiput densely punctate. Dorsal profile of gena rounded in dorsal view; width gradually narrowing posteriorly ( Fig. 1D). Occipital carina complete. Malar space 1.0–1.1 × as long as basal width of mandible. Mandible flat at base; lower tooth longer than upper tooth. Antenna with 23–25 flagellomeres; not flattened and tapped. FL I 2.1–2.3 × as long as maximum depth in lateral view, 1.1 × as long as FL II.

Mesosoma. Pronotum rugulose ventrally; densely punctate dorsally. Epomia short; section on border of collar and pronotum present. Mesoscutum densely punctate; without notaulus or slightly defined as trace-like. Scutellum sparsely punctate; weakly convex in lateral view. Mesopleuron longitudinally rugulose and punctate; punctures largely partly united into groove-like foveola ( Fig. 1E); without conspicuous smooth area around speculum. Epicnemial carina present laterally and ventrally. Sternaulus deep in anterior 0.4 of mesopleuron. Metapleuron obliquely rugulose; without juxtacoxal carina. Propodeum rugose or rugulose except for area externa finely and sparsely punctate with smooth ISP; anterior transverse carina absent ( Fig. 1G); posterior transverse carina complete, inverted U-shaped ( Fig. 1G); lateromedian longitudinal carina weak and partly indistinct in front of posterior transverse carina ( Fig. 1G); lateral longitudinal carina complete; pleural carina complete; area superomedia indistinct; apophysis small but pointed; spiracle elliptic. Fore wing length 5.3–7.3 mm. Areolet slightly wider than long; width slightly narrowing anteriorly; received vein 2m-cu at near or slightly beyond middle ( Fig. 1F). Fore wing vein 1cu-a interstitial to vein M&RS ( Fig. 1F). Nervellus subvertical; intercepted near posterior end of vein. Hind femur reticulate coriaceous; with short setae ( Fig. 77D); 4.2–4.65 × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma. T I 2.2–2.3 × as long as maximum width; longitudinally striate except for smooth area of apex ( Fig. 1H); latero-median carina absent; dorso-lateral carina complete and weak. T II 1.25–1.4 × as long as maximum width; smooth; finely punctate laterally. Thyridium present; close to anterior margin of T II; slightly depressed; ca. 2.0 × as wide as length. T III to T V finely punctate. Ovipositor sheath 0.9–1.05 × as long as hind tibia, 1.5–1.6 × as long as T I. Ovipositor straight; apex sharp; apex of lower valve with teeth ( Fig. 78A).

Colouration ( Figs. 1A–H). Body (excluding wings) black to blackish-brown. Setae silver; weakly tinged with brown in head and mesoscutum. Subapical part of mandible and lower part of clypeus tinged with reddish-brown.

Hind femur 6.0–6.25 × as long as maximum depth in lateral view. T I 3.85–4.15 × as long as maximum width. T II 1.8–2.0 × as long as maximum width. Face, ventro-lateral sides of face, malar space, clypeus, mandible except for teeth, and palpi yellow to ivory. Ventral surface of scape usually with yellow marking. Postero-dorsal corner of pronotum, posterior part of scutellum, and subtegular ridge yellow. Fore coxa with yellow marking(s). Fore and mid legs paler than female; trochanters and trochantelli largely yellow; fore femur and fore and mid tibiae and tarsi except for each TS V yellow to reddish-yellow.
