Description. Female (n=4). Body length 4.3–4.8 (HT: 4.8) mm. Body polished, covered with silver setae.
Head. Clypeus 1.9–2.0 (HT: 2.0) times as wide as maximum length, its anterior margin rounded. Face densely punctate, with a median weak convexity (Fig. 28B). MSL 1.0 times as long as BWM. Frons rugose, the rugae largely transverse. Gena punctate. Vertex punctate and largely transversely striate. OOL slightly shorter than POL. OOL and POL longer than OD. Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base. Upper tooth of mandible slightly longer than lower tooth. Base of mandible flat. Antenna with 24–25 (HT: 24) flagellomeres. FL III 6.7 times as long as maximum depth in lateral view.
Mesosoma. Upper side of collar with a weak median carina. Lateral part of pronotum largely rugose except for a smooth area dorsally. Epomia short. Mesoscutum with a median longitudinal groove on the median lobe (Fig. 28D). Notaulus long, its posterior ends joined with each other posteriorly (Fig. 28D). Area along notaulus transversely striae (Fig. 28D). Scutellum smooth except for lateral part partly rugulose, with a lateral longitudinal carina except for apex. Mesopleuron longitudinally striate except for smooth speculum and an anterior small smooth area. Posterior transverse carina of mesosternum complete. Metapleuron punctate, with a complete juxtacoxal carina. Anterior and posterior transverse carinae of propodeum complete (Fig. 65I). Pleural carina complete. Lateral longitudinal carina of propodeum absent. Area basalis distinct (Fig. 65I). Area superomedia indistinct laterally (Figs 28E, 65I). Anterior and posterior parts of propodeum transversely, obliquely, and irregularly rugulose. Median part of propodeum longitudinally rugulose (Figs 28E, 65I). Length of fore wing 3.6–3.9 (HT: 3.9) mm. Areolet absent (Fig. 28F). Vein 2m-cu of fore wing with two bullae (Fig. 28F). Nervellus inclivous, intercepted slightly behind middle. Hind femur 5.1–5.2 (HT: 5.2) times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 0.9–0.95 (HT: 0.9): 0.65–0.7 (HT: 0.7): 0.3–0.4 (HT: 0.4): 0.4. Tarsal claws simple.
Metasoma. T I 1.7 times as long as maximum width, longitudinally striate except for smooth posterior margin (Figs 28C, G). Median dorsal carina of T I indistinct. Dorsolateral carina of T I complete. T II and T III covered with longitudinal striae except for smooth posterior area on posterior 0.4 (Figs 28C, G). T IV finely and sparsely punctate, with some weak longitudinal striae medially. T V and T VI largely smooth medially. Ovipositor sheath 0.7–0.75 (HT: 0.75) times as long as hind tibia. Ovipositor straight, with a nodus and ventral teeth (Fig. 66H).
Coloration (Figs 28A–G). Body (excluding wings and legs) black to blackish brown. Basal parts of antenna yellowish brown to reddish brown. Median parts of face and clypeus tinged with yellowish brown to reddish brown. Mandible yellow except for darkened apex. Palpi and tegula yellowish brown to yellow. Margins of pronotum, mesoscutum, and mesopleuron partly tinged with reddish brown. Scutellum and postscutellum dark reddish brown. T I reddish brown, its lateral sides more or less darkened. T II and T III reddish brown. T IV dark reddish brown anteriorly, reddish brown posteriorly. T V to T VII dark reddish brown except for reddish brown posterior margin. Membranous part of metasomal sternites whitish yellow. Ovipositor reddish brown. Wings hyaline, with a longitudinal clouded band just behind pterostigma and a small, clouded area subbasally.

Male. Unknown.
Distribution. Japan (Yakushima Is.).
