Description. Female (n = 4). Body length 6.1–6.8 (HT: 6.8) mm, covered with silver setae.

Head 0.5–0.6 (HT: 0.57) × as long as wide in dorsal view, matt. Clypeus 2.7–2.8 (HT: 2.7) × as broad as high, sparsely punctate and polished, convex in lateral view, lower margin with a median concavity ( Fig. 40L View Fig ). Face 2.0 × as broad as high, slightly convex medially in lateral view. Dorsal profile of gena as Fig. 38K View Fig . Occipital carina complete. Length of malar space 0.4–0.5 (HT: 0.5) × as long as basal width of mandible. Base of mandible flat. POL 0.95–1.2 (HT: 0.95) × as long as OD. OOL 1.4–1.6 (HT: 1.6) × as long as OD. Antenna with 34–37 (HT: 37) flagellomeres. FL I 5.0 × as long as maximum depth, 1.55– 1.65 (HT: 1.55) × as long as FL II. Length of FL I plus FL II 1.3 × as long as eye height.

Mesosoma polished and punctate. Epomia absent. Pronotum rugulose along collar. Mesoscutum with weak notaulus, interspace of punctures slightly coriaceous. Epicnemial carina present laterally and ventrally, its dorsal end situated near anterior margin of mesopleuron. Speculum with large smooth area ( Fig. 19C View Fig ). Propodeum with all carinae except for anterior transverse carina. Lateromedian longitudinal carina largely indistinct ( Fig. 19D View Fig ). Median part of posterior transverse carina absent. Anterior part of lateral longitudinal carina absent. Fore wing length 5.8–7.3 (HT: 7.3) mm. Areolet absent. Fore wing vein 1cu-a postfurcal to vein M&RS ( Fig. 19A View Fig ). Nervellus slightly inclivous, intercepted posterior the middle. Tarsal claws simple. Hind femur 4.75–4.9 (HT: 4.75) × as long as maximum depth in lateral view. Ratio of length of hind first to fifth tarsomeres 4.1–4.2 (HT: 4.2): 2.0: 1.5: 0.9–1.0 (HT: 1.0): 1.0–1.1 (HT: 1.0).

Metasoma matt. T I 1.4–1.5 (HT: 1.5) × as long as maximum width, with latero-median longitudinal carina (sometimes weak), its posterior end situated near spiracle. T II 0.75–0.8 (HT: 0.75) × as long as maximum width. Setae of subgenital plate directed backwards. Ovipositor sheath with short setae (shorter than half depth of ovipositor sheath) apically. Ovipositor sheath 0.25 × as long as hind tibia.

Colouration ( Figs. 19A–D View Fig ). Body (excluding wings and legs) black. Clypeus, mandible except for teeth, palpi, ventral spot of scape, postero-dorsal corner of pronotum, scutellum, postscutellum, tegula, and subtegular ridge yellow to whitish yellow. Posterior margins of T II to T VII, lateral sides of T III to T VII, and metasomal sternites except for sclerites white. Wings hyaline. Veins and pterostigma brown except for yellow wing base. Fore and mid legs whitish yellow. Hind coxa and femur reddish yellow. Hind trochanter, trochantellus, tibia except for base and apical part, and hind tibial spurs whitish yellow. Hind tibia except for base and apical part and hind tarsus blackish brown.

Male. Unknown.

Distribution. Japan (Honshu).

Bionomics. Unknown.

Etymology. The specific name is from Japan.

Remarks. This species resembles Ca. liosternus (Thomson, 1894) in body colouration but can be distinguished by the length of FL I plus FL II 1.3 × as long as the eye height (0.95–1.1 × in Ca. liosternus ) and the brown pterostigma (dark in Ca. liosternus ).
