Description. Female (n = 8). Body matt; lustre dull; covered with setae; body length 7.8–11.0 mm.

Head 0.6–0.65 × as long as wide in dorsal view. Clypeus 3.0 × as wide as long; slightly convex in lateral view; transversely rugose and punctate dorsally; lower margin weakly rounded in frontal view, obtuse in lateral view. Face 0.45 × as long as minimum width; weakly convex medially; matt; punctate. Anterior tentorial pit small. Frons matt; finely punctate dorsally; weakly concave above antennal sockets; with pair of small tubercles ventrolaterally. POL 1.1–1.3 × as OD. OOL 1.3–1.5 × as OD. Gena and occiput densely punctate. Dorsal profile of gena rounded in dorsal view; width gradually narrowing posteriorly ( Fig. 26D). Occipital carina complete. Malar space 0.7–0.75 × as long as basal width of mandible. Mandible flat at base; lower tooth longer than upper tooth. Antenna with 30–33 flagellomeres; apical part flattened below and tapped to slender apex ( Fig. 26B). FL I 2.0–2.25 × as long as maximum depth in lateral view, 0.9–0.95 × as long as FL II.

Mesosoma densely and finely punctate ( Fig. 26E). Epomia short; section on border of collar and pronotum present ( Fig. 26E). Mesoscutum with short and weak notaulus. Scutellum weakly convex. Mesopleuron without conspicuous smooth area around speculum; partly covered with oblique or longitudinal fine striae ( Fig. 26E). Epicnemial carina present laterally and ventrally. Sternaulus deep in anterior 0.4 of mesopleuron. Metapleuron finely and sparsely punctate; with complete or partly defined juxtacoxal carina. Propodeum sparsely and finely punctate; with long dorsal face (longer than area postero); anterior transverse carina absent ( Fig. 26H); posterior transverse carina largely absent medially, weak and not sharply defined laterally ( Fig. 26H); lateromedian longitudinal carina absent; lateral longitudinal carina weak and largely indistinct; pleural carina complete; area superomedia not defined; apophysis absent; spiracle oval. Fore wing length 7.0– 9.8 mm. Areolet as long as maximum width; width steeply narrowing anteriorly; received vein 2m-cu received vein 2m-cu at slightly beyond to middle ( Fig. 26F). Fore wing vein 1cu-a slightly antefurcal to vein M&RS ( Fig. 26F). Nervellus inclivous; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 4.1–4.25 × as long as maximum depth in lateral view. Dorsal face of tibiae with robust, large, conspicuous setae ( Fig. 26G). Tarsal claws simple.

Metasoma finely punctate; ISP weakly coriaceous. T I 2.25–2.9 × as long as maximum width; latero-median carina absent; dorso-lateral carina absent. T II 0.6–0.75 × as long as maximum width. Thyridium present; close to anterior margin of T II; slightly depressed to flat; ca. 2.0 × as wide as length. Ovipositor sheath 1.0–1.2 × as long as hind tibia, 1.75–1.85 × as long as T I. Ovipositor straight; apex sharp; apex of lower valve with teeth ( Fig. 78U).

Colouration ( Figs. 26A–H). Body (excluding wings) black to blackish-brown. Setae silver to pale yellowish-brown. Mandible except for base and apex, clypeus, ventral surfaces of scape and apical part of flagellum, and fore tibia and tarsus partly tinged with brown to yellowish-brown. FL VI to FL X (or XI) with white markings. Posterior margin of metasomal tergites sometimes narrowly tinged with reddish-brown. Thyridium and ovipositor reddish-brown. Wings slightly brownish-hyaline. Veins and pterostigma blackish-brown except for brown wing base.

Male (n =2). Similar to female ( Figs. 27A–E). Body length 11.6 mm (in KPM-NK 103039). Head 0.55 × as long as wide in dorsal view. Clypeus 3.4 × as wide as long. OOL and POL 1.0 × as OD, respectively. Face 0.5 × as long as minimum width. Malar space 0.3 × as long as basal width of mandible. Antenna not flattened below and tapped to slender apex; with tyloids on FL XII to FL XIV ( Fig. 27D). FL I 2.7 × as long as maximum depth in lateral view, 1.35 × as long as FL II. Posterior transverse carina and lateral longitudinal carina of propodeum complete. Hind femur 5.5 × as long as maximum depth in lateral view. T II 1.0 × as long as maximum width. Facial and frontal orbits tinged with yellowish-brown. FL XI to FL XIV with white markings. Palpi yellowish-brown.
