Frons, gena, and vertex finely and sparsely punctate. OOL slightly longer than POL and OD. POL as long as OD. Occipital carina complete, its lower end joined with hypostomal carina distant from mandibular base. Upper tooth of mandible as long as lower tooth. Base of mandible flat. Antenna with 21 flagellomeres. Subapical part of flagellum slightly wider than basal part. 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 smooth except for narrowly punctate dorsally and ventrally. Epomia long (Fig. 24D). Mesoscutum smooth, with a few, sparse, and fine punctures and a median longitudinal groove on the median lobe (Fig. 24D). Notaulus long, its posterior ends closed each other (Fig. 24D).

Metapleuron punctate, with a complete juxtacoxal carina. Anterior and posterior transverse carinae of propodeum complete (Fig. 65G). Pleural carina complete. Lateral longitudinal carina of propodeum present except for anterior section. Area basalis distinct (Fig. 65G). Area superomedia distinct (Fig. 65G). Propodeum largely smooth, with fine punctures. Length of fore wing 3.2 mm. Areolet absent (Fig. 24E). Vein 2m-cu of fore wing with two bullae. Nervellus inclivous, intercepted slightly behind middle. Hind femur 4.1 times as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 2.0: 0.9: 0.55: 0.3: 0.5. Tarsal claws simple.

Veins yellowish brown to blackish brown. Pterostigma blackish brown. Legs reddish brown. Coxae except for dorsal surface of hind coxa, trochanters, trochantelli except for apical part of hind trochantellus, and tibial spurs whitish yellow.

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