Abstract: Cryptopimpla aino sp. nov. urn:lsid:zoobank.org:act: F81482EE-5EAD-49D1-80AB-BD7FB4E65D45 (Figs 1G, 2A–F) Type series. Holotype: F, JAPAN, Hokkaido, Kamikawa Town, Mikuni-toge, 2–12. VI. 2010, N. Kuhara leg., MsT. (KPMNH). Paratype: JAPAN: [Hokkaido] 1F, same data as holotype (KPMNH). Description. Female (n = 2). Body length 5.8–5.9 (HT: 5.8) mm, matt and granulate (Figs 2B–F), covered with silvery setae. Head 0.65 × as long as wide. Clypeus 2.0 × as broad as high, sparsely punctate, convex in lateral view. Face 2.0 × as broad as high, convex medially in lateral view. Malar space 0.9–1.0 (HT: 1.0) × as long as basal mandibular width. POL 1.4–1.5 (HT: 1.4) × as long as OD. OOL 1.6–1.8 (HT: 1.6) × as long as OD. Gena convex in dorsal view. Lower end of occipital carina joined to hypostomal carina distant to mandibular base.Antenna with 30 flagellomeres. FL I 5.0 × as long as maximum depth in lateral view and 1.45 × as long as FL II. All segments of flagellum longer than maximum width; preapical flagellomeres weakly elongate, ca. 1.1–1.3 times as long as wide. Mesosoma. Mesoscutum, scutellum, mesopleuron, and metapleuron finely punctate. Speculum without conspicuous smooth area (Fig. 2D). Propodeum with pleural carina and short, trace-like median part of posterior transverse carina. Fore wing length 5.4–5.6 (HT: 5.4) mm. Junction of vein Cu1 and vein Cu-a slightly distant to junction of veins Rs+M and M+Cu.Areolet small, narrowly truncate anteriorly; its length and width not significantly different; received vein 2m-cu slightly distant of the outer angle. Nervellus intercepted posterior to middle. Hind femur 6.2–6.3 (HT: 6.3) × as long as maximum depth in lateral view. Hind tibia with few robust and large setae. Ratio of length of hind first to fifth tarsomeres 4.0: 2.0: 1.3: 0.7: 0.8. Tarsal claws simple except for some minute basal teeth, weakly bent (Fig. 1G). Metasoma. T I 1.6–1.7 (HT: 1.7) × as long as maximum width. T II 1.0 × as long as maximum width. Ovipositor sheath 0.75–0.8 (HT: 0.75) × as long as hind tibia. Coloration (Figs 2A–F). Body (excluding wings and legs) black. Clypeus except for dorsal margin yellowish-brown. Palpi dark yellowish-brown to blackish-brown. Apex of mandibular teeth reddish-brown. Tegula ivory. Scutellum sometimes narrowly tinged with red apically. Posterior part (ca. posterior 1/3) of T I and T II to T IV red to reddish-brown. T II with subbasal black area. Each posterior margin of T V and T VI narrowly tinged with red. Membranous part of metasomal sternites ivory. Ovipositor yellowish-brown. Wings hyaline. Veins and pterostigma brown to yellowish-brown except for yellow to ivory wing base. Coxae and trochanters black. Trochantelli, femora, tibiae, and tarsi reddish-brown. Apex of hind femur and fifth tarsomere of hind tarsus more or less darkened. Male. Unknown. Distribution. Japan (Hokkaido). Bionomics. Host unknown. Adults were collected in June. Etymology. The species name is derived from the native people in Hokkaido, “Ainu”. Remarks. This species resembles C. anomala (Holmgren, 1860) in matt body with red areas but can be distinguished from the latter by the following combination of character states: malar space as long as or shorter than mandibular base (longer than mandibular base in C. anomala); speculum without conspicuous smooth area (with smooth area in C. anomala); coxae and trochanters black (red in C. anomala).
