Body length 6.5–7.8 (HT: 7.5) mm, polished and covered with dense punctures and silvery setae; ISP smooth. Head 0.6 × as long as wide. Clypeus 2.3–2.5 (HT: 2.5) × as broad as high, convex in lateral view. Face 2.0 × as broad as high, weakly convex medially in lateral view. Malar space 0.5–0.6 (HT: 0.6) × as long as basal mandibular width. POL 1.3–1.75 (HT: 1.4) × as long as OD. OOL 1.9–2.0 (HT: 1.9) × as long as OD. Gena strongly convex in dorsal view. Lower end of occipital carina joined to hypostomal carina slightly distant to mandibular base. Antenna with 30 flagellomeres. FL I 4.0 × as long as maximum depth and 1.4 × as long as FL II. All apical segments of flagellum longer than maximum width; preapical flagellomeres elongate, ca. 1.3–1.5 times as long as wide. Mesosoma. Speculum with large smooth area (Fig. 12D). Propodeum without carina except for pleural carina (partly weak and sometimes indistinct); posterior transverse carina absent but short, trace-like ridge sometimes present medially. Fore wing length 5.3–6.7 (HT: 6.1) mm. Junction of vein Cu1 and vein Cu-a slightly distant to junction of veins Rs+M and M+Cu.Areolet small, pointed anteriorly; its length and width not significantly different; received vein 2m-cu slightly distant of outer angle. Nervellus intercepted posterior to middle. Hind femur 4.8–5.6 (HT: 5.15) × as long as maximum depth in lateral view. Hind tibia with only a few robust and large setae. Ratio of length of hind first to fifth tarsomeres 4.2–4.3 (HT: 4.3): 2.0: 1.4–1.6 (HT: 1.6): 0.8–0.9 (HT: 0.9): 0.95–1.0 (1.0). Tarsal claws simple, weakly bent (Fig. 1 Q). Metasoma. T I 1.1–1.3 (HT: 1.1) × as long as maximum width; punctate laterally, smooth medially and posteriorly (Fig. 12 F). T II 06–0.75 (HT: 0.65) × as long as maximum width; punctate except for smooth (usually slightly coriaceous) posterior margin (Fig. 12 F). T III to T V coriaceous, with fine and small punctures. Ovipositor sheath 1.0–1.1 (HT: 1.1) times as long as hind tibia. Coloration (Figs 12A–F). Body (excluding wings and legs) black. Lower part of clypeus yellow. Mandible yellow except for black to blackish-brown base and teeth. Palpi yellow. Flagellum sometimes partly tinged with yellowish-brown to brown. Dorso-lateral corner of pronotum, small tinge of subtegular ridge, and tegula yellow to ivory. Each posterior margin of metasomal tergites narrowly tinged with reddish-brown to yellowish-brown. Membranous part of metasomal sternites ivory. Ovipositor reddish-brown. Wings hyaline. Veins and pterostigma brown to yellowish-brown except for yellow wing base. Fore and mid coxae, trochanters, and trochantelli ivory. Fore and mid femora, tibiae, and tarsi yellowish-brown. Hind coxa except for apex, trochanter, femur except for base and apex, subbasal small spot and apical part of tibia, and tarsus more black to blackish-brown. Apex of hind coxa, hind trochantellus, base and apex of hind femur, and hind tibia except for subbasal spot and apical part ivory. Male. Unknown. Distribution. Japan (Hokkaido and Kyushu). Bionomics. Host unknown. Adults were collected in April, June, and July. Remarks. This species resembles C. genangusta but can be distinguished by the short, robust, and smoother T I, the wider T II, the speculum with large smooth area, and the smaller body size (see above key).
