Description. Female (n=7). Body length 6.7–7.2 mm. Body polished, covered with silver setae.

Head. Clypeus 2.05–2.2 times as wide as maximum length, smooth except for area along dorsal margin punctate, its anterior margin weakly rounded. Face punctate except for lateral smooth areas, with a median convexity ( Fig. 20B ). MSL 1.4–1.6 times as long as BWM. Frons rugose-punctate, with narrow smooth area just above antennal sockets. Gena and vertex finely punctate. OOL as long as or slightly shorter than POL. OOL and POL longer than OD. Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base by the length of BWM. Upper tooth of mandible slightly shorter than lower tooth. Base of mandible flat. Antenna with 25–28 flagellomeres. FL I, FL II, and FL III almost equal in length. FL III 5.0 times as long as maximum depth in lateral view.

Mesosoma. Upper side of collar without a median carina. Lateral part of pronotum striate and punctate. Epomia absent. Mesoscutum irregularly or obliquely rugose, without a median longitudinal groove on the median lobe. Notaulus short and weak. Scutellum smooth except for a few punctures, with a lateral longitudinal carina except for apex. Postscutellum smooth. Mesopleuron rugose-punctate except for smooth speculum. Posterior transverse carina of mesosternum complete. Metapleuron rugose-punctate, with a complete juxtacoxal carina. Anterior and posterior transverse carinae of propodeum complete except for median section weak or absent. Pleural carina complete. Anterior section of lateral longitudinal carina of propodeum weak and partly indistinct. Lateromedian longitudinal carina complete except for posterior section partly absent. Area superomedia indistinct anteriorly and posteriorly, elongate ( Fig. 65F ). Propodeum largely covered with shallow rugae. Propodeum without projections. Length of fore wing 4.9–5.1 mm. Areolet absent ( Fig. 20C ). Vein 2rs-m absent ( Fig. 20C ). Vein 2m-cu of fore wing with two bullae ( Fig. 20C ). Nervellus inclivous, intercepted posteriorly. Hind femur 5.2–5.5 times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 0.9: 0.6: 0.4: 0.4. Tarsal claws simple.

Metasoma. T I 1.4 times as long as maximum width, largely smooth ( Fig. 20D ). Median dorsal carina of T I absent. Dorsolateral carina of T I complete. T II and T III densely and finely punctate with some longitudinal striae except for smooth area on posterior 0.6. T IV to T VII finely and sparsely punctate. Ovipositor sheath 0.64–0.78 times as long as hind tibia. Ovipositor straight, with a nodus and ventral teeth.

Coloration ( Figs 20A–D ). Body (excluding wings) blackish brown to black. Antenna, apex of mandible, base of hind tibia more or less tinged with reddish brown. FL VII and T VIII paler than other segments. Fore femur, tibia, and tarsus largely reddish brown. Posterior margin of T II sometimes narrowly tinged with reddish brown. Ovipositor reddish brown. Wings hyaline, with a longitudinal clouded band just behind pterostigma and a small, clouded area subbasally. Veins and pterostigma brown to blackish brown.

Male. Unknown.
