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 ). Propodeum with all carinae except for anterior transverse carina. Lateromedian longitudinal carina largely indistinct ( Fig. 19D ). 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 ).

(KPM-NK 84961, holotype, female) ― A: lateral habitus; B: head, frontal view; C: mesopleuron and metapleuron; D: propodeum, dorsal view. 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 ). 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 ).
