Description. Female (n =2). Body punctate and polished; covered with setae; body length 9.5–11.5 mm.

Head 0.6 × as long as wide in dorsal view. Clypeus 2.5 × as wide as long; slightly convex in lateral view; punctate and coriaceous dorsally, smooth ventrally; lower margin subtruncate in frontal view, obtuse in lateral view. Face 0.38 × as long as minimum width; weakly convex medially; matt laterally, densely punctate and coriaceous medially. Frons weakly concave above antennal sockets; matt and punctate dorsally, coriaceous and partly transversely rugulose ventrally. POL 1.25 × as OD. OOL 1.3 × as OD. Gena and occiput finely and sparsely punctate. Dorsal profile of gena nearly straight in dorsal view; width gradually narrowing posteriorly ( Fig. 61D). Occipital carina complete. Malar space 1.0–1.1 × as long as basal width of mandible. Mandible flat at base; lower tooth equal in length of upper tooth. Antenna with 30 flagellomeres; apical part flattened below and tapped to slender apex. FL I 2.6 × as long as maximum depth in lateral view, 0.9 × as long as FL II.

Mesosoma. Pronotum rugulose ventrally ( Fig. 61E). Epomia absent. Mesoscutum densely punctate; without notaulus ( Fig. 61D). Scutellum sparsely punctate; slightly convex in lateral view. Mesopleuron with conspicuous smooth area around speculum ( Fig. 61E). Epicnemial carina present laterally and ventrally. Sternaulus deep in anterior 0.4 of mesopleuron. Metapleuron punctate anteriorly, transversely strigose posteriorly; with complete juxtacoxal carina. Propodeum finely and weakly coriaceous; area along posterior transverse carina rugose or rugulose; anterior transverse carina absent; posterior transverse carina complete, inverted V-shaped ( Fig. 61G); lateromedian longitudinal carina present anteriorly; lateral longitudinal carina complete; pleural carina complete; area superomedia partly indistinct; area externa punctate; apophysis absent; spiracle oval. Fore wing length 8.3 mm. Areolet slightly longer than wide; width steeply narrowing anteriorly; received vein 2m-cu at slightly beyond to middle ( Fig. 61F). Fore wing vein 1cu-a interstitial to vein M&RS ( Fig. 61F). Nervellus subvertical; intercepted near posterior end of vein. Hind femur reticulate coriaceous; 4.9 × as long as maximum depth in lateral view. Tarsal claws simple.

Metasoma weakly to slightly coriaceous except for posterior smooth area of T I; finely and sparsely punctate. T I 1.85–1.95 × as long as maximum width; lateromedian carina absent posteriorly; dorso-lateral carina complete except for area near spiracle. T II 0.8 × as long as maximum width. Thyridium present; close to anterior margin of T II; slightly depressed; ca. 2.0 × as wide as length. Ovipositor sheath 0.95–1.1 × as long as hind tibia, 1.85–1.9 × as long as T I. Ovipositor straight; apex obtuse; apex of lower valve with teeth ( Fig. 79 AA).

Colouration ( Figs. 61A–G). Body (excluding wings) black to blackish-brown. Setae silver; more or less brownish on head and mesoscutum. Subapical part of mandible, ventral surface of apical part of flagellum, and posterior margin of T II tinged with reddish-brown to yellowish-brown. FL VII to FL X with white markings. Fore femur, tibia, and tarsus partly tinged with brown to dark yellowish-brown. Thyridium and ovipositor reddish-brown. Apex of metasoma ivory. Wings hyaline. Veins and pterostigma blackish-brown to brown except for yellowish-brown wing base.

Male. No additional material is available.
