Ontake-san, Tanohara, 31.VII.2013, S. Shimizu leg. (KPMNH). Paratype: JAPAN: [Honshu] 1F, Nagano Pref., Japan Alps, Tokusawa, 6.VIII.1955, Y. Utsugi leg. (NARO). Description. Female (n = 2). Body length 6.4–7.0 (HT: 7.0) mm, polished and covered with dense punctures with coriaceous ISP and silvery setae. Head 0.65 × as long as wide. Clypeus 2.0 × as broad as high, sparsely punctate, convex in lateral view. Face 1.75–1.8 (HT: 1.8) × as broad as high, slightly convex medially in lateral view. Malar space 0.7 × as long as basal mandibular width. POL 1.6 × as long as OD. OOL 1.5–1.6 (HT: 1.6) × as long as OD. Gena convex in dorsal view. Lower end of occipital carina joined to hypostomal carina slightly distant to mandibular base. Antenna with 29–30 (HT: 30) flagellomeres. FL I 5.0 × as long as maximum depth in lateral view and 1.45–1.55 (HT: 1.55) × as long as FL II. All apical segments of flagellum longer than maximum width; preapical flagellomeres elongate, ca. 1.5 times as long as wide. Mesosoma. Speculum with conspicuous smooth rea (Fig. 11E). Propodeum with pleural carina and posterior transverse carina (Figs 11 F, G). Fore wing length 6.1 mm. Junction of vein Cu1 and vein Cu-a slightly distant or opposite to junction of veins Rs+M and M+Cu. Areolet small, pointed or narrowly truncate anteriorly; its length and width not significantly different; received vein 2m-cu slightly distant of outer angle. Nervellus intercepted posterior to middle. Hind femur 5.8–6.8 (HT: 5.8) × 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 4.3–4.6 (HT: 4.3): 2.0: 1.3–1.4 (HT: 1.3): 0.7–0.8 (HT: 0.7): 0.75–0.8 (HT: 0.75). Tarsal claws pectinate, weakly bent apically (Fig. 1 P). Metasoma coriaceous with sparse and fine punctures (Fig. 11 H). T I 1.6–1.7 (HT: 1.7) × as long as maximum width. T II 0.95–1.0 (HT: 1.0) × as long as maximum width. Ovipositor sheath 0.6–0.65 (HT: 0.6) × as long as hind tibia. Colouration (Figs 11 A–H). Body (excluding wings and legs) black. Clypeus, face except for black areas below each antennal socket and median longitudinal stripe, malar space, mandible except for teeth, ventral spots of scape and pedicel, and palpi yellow to ivory. Postero-dorsal corner of pronotum, antero-lateral longitudinal stripes of mesoscutum, tegula, pair of narrow spots of scutellum (sometimes absent), and subtegular ridge yellow to ivory. Posterior margins of each metasomal tergite narrowly tinged with dark reddish-brown. Membranous parts of metasomal sternites ivory. Ovipositor yellowish-brown. Wings hyaline. Veins and pterostigma brown to yellowish-brown except for yellow wing base. Legs reddish-brown to yellowish-brown. Fore and mid coxae and all trochanters and trochantelli ivory. Apical part of hind femur and basal part of hind tibia tinged with ivory. Hind coxa largely blackish-brown. Male. Unknown. Distribution. Japan (Honshu). Bionomics. Host unknown. Adults were collected in July and August. Etymology. The species name is derived from the Latin “ alpina ” plus Nippon (= Japan), meaning Japanese mountains. This species is found in mountainous areas of Japan. Remarks. This species resembles C. genalis (Thomson, 1877) but can be distinguished from the latter by the following combination of character states: face with large yellow area(s) (black in C. genalis); hind coxa largely blackish-brown (reddish-brown in C. genalis); ovipositor sheath 0.6–0.65 × as long as hind tibia (0.5 × in C. genalis).
