Description. Female (n=4). Body length 8.2–9.5 mm. Body polished, covered with silver setae.

Head. Clypeus 1.5–1.8 times as wide as maximum length, matt, punctate, its anterior margin weakly rounded and transversely impressed. Face matt and densely punctate. MSL 1.2 times as long as BWM. Frons, gena, and vertex finely and densely punctate except for smooth area above antennal sockets. OOL as long as POL. OOL and POL slightly longer than OD. Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base. Upper tooth of mandible almost as long as lower tooth. Base of mandible convex. Antenna with 31–32 flagellomeres, subapical part slightly widened. The widened part of flagellum largely flattened ventrally. FL III 4.0 times as long as maximum depth in lateral view.

Mesosoma 1.7 times as long as maximum depth in lateral view. Upper side of collar with a high median carina. Lateral part of pronotum densely punctate dorsally, largely smooth ventrally. Epomia short and weak. Mesoscutum densely punctate. Notaulus distinct, fading our near center of mesoscutum. Scutellum densely punctate, without a lateral longitudinal carina except for base. Mesopleuron smooth except for punctures on dorsal and ventral areas and some longitudinal striae on a median area below speculum. Posterior transverse carina of mesosternum largely absent in front of mid coxae. Metapleuron punctate, with a complete juxtacoxal carina. Anterior and posterior transverse carinae of propodeum complete. Pleural carina and lateral longitudinal carina of propodeum complete. Area basalis distinct. Area superomedia indistinct laterally. Anterior part of propodeum densely punctate. Median and posterior parts of propodeum longitudinally, obliquely, and irregularly rugulose. Propodeum without projections. Length of fore wing 6.5–7.3 mm. Areolet present ( Fig. 44D ). Vein 2m-cu with two bullae. Nervellus inclivous, intercepted posteriorly ( Fig. 44D ). Hind femur 4.2–4.6 times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 1.0: 0.6: 0.35–0.4: 0.4–0.5. Tarsal claws simple.

Metasoma. T I 1.3–1.4 times as long as maximum width, densely punctate. Median dorsal carina of T I present except for posterior part. Dorsolateral carina of T I complete. T II to T IV wider than long, densely punctate ( Fig. 44C ). T V to T VII covered with fine punctures. T VII and T VIII weakly elongated. Ovipositor sheath 0.75 times as long as hind tibia, its apical part distinctly expanded ( Figs 44E , 66O ). Ovipositor straight, compress laterally, with a nodus and ventral teeth ( Fig. 66N ).

Coloration ( Figs 44A–E ). Body (excluding wings) black to blackish brown. Mandible yellowish brown except for darkened apex and base. Fore and mid femora, tibiae. and tarsi more or less tinged with yellowish brown to reddish brown. Base of tibiae white. Tibial spurs whitish yellow. Membranous part of metasomal sternites yellowish brown. Ovipositor reddish brown. Wings hyaline. Veins and pterostigma brown to blackish brown.

Male. Not studied in this study.
