Type series. Holotype: NIAES, F, Hokkaido, Mt. Tarumaezan , 12–21. VII. 1998, K. Konishi (MsT) .
Paratypes: NIAES, 2 F & 5 M, same data of holotype .
Description. Female (n=3). Body covered with silver setae, length 7.3–8.0 (HT: 8.0) mm.
Head 0.55–0.6 (HT: 0.59) × as long as wide. Clypeus sparsely punctate, 0.55–0.63 (HT: 0.56) × as long as maximum wide, weakly convex in lateral view, its apical margin rounded, without a median tooth or convexity. Face 0.5 × as long as maximum wide, finely coriaceous, densely and finely punctate, weakly convex medially in lateral view. Frons dull, irregularly rugose dorsally, transversely rugose ventrally. Length of malar space 1.05–1.1 (HT: 1.1) × as long as basal mandibular width. Lower part of occipital carina not raised and without a projecting lobe, its lower end joining hypostomal carina. Base of mandible almost flat. Upper tooth of mandible as long as lower tooth. OD: POL: OOL = 1.0: 1.5–1.6 (HT: 1.5): 1.2–1.3 (HT: 1.2). Flagellum with 36–37 (HT: 37) segments. FL I 6.67 × as long as maximum depth in lateral view and 1.36–1.43 (HT: 1.36) × as long as FL II.
Mesosoma polished. Lateral aspect of pronotum punctate dorsally, longitudinally strigose ventrally and posteriorly. Epomia present. Posterior end of notauli reached to middle of mesoscutum. Mesoscutum and scutellum punctate. Mesopleuron largely covered with reticulate rugose, with a small smooth area on speculum. Mesosternum without a posterior transverse carina. Metapleuron reticulate rugose dorsally and obliquely rugose ventrally. Juxtacoxal carina present except for median part absent. Propodeum reticulate rugose on area externa, area postero and area postero-externa and longitudinally rugose on area superomedia and area dentipara ( Fig. 6G View Fig ). Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete. Posterior transverse carina complete, its dorso-lateral part more or less strongly raised but not form as strong apophysis ( Figs 6D, G View Fig ). Pleural carina present but partly indistinct. Propodeal spiracle elongate.Area basalis widened anteriorly. Fore wing length 5.8–6.0 (HT: 6.0) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m convergent anteriorly ( Fig. 6H View Fig ). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu ( Fig. 6H View Fig ). Hind femur 5.3–5.6 (HT: 5.4) × as long as maximum depth in lateral view. Hind tibia in lateral view with spines projecting distinctly above dorsal margin of tibia. Hind TS I: II: III: IV: V = 4.0–4.1 (HT: 4.0): 2.0: 1.4: 0.75–0.8 (HT: 0.8): 4.6–5.0 (HT: 5.0).
Metasoma dull, covered with very sparse, fine punctures. T I 4.6–4.75 (HT: 4.75) × as long as maximum width, with smooth area posteriorly, without latero-median carina, dorso-lateral carina and a pair of small convexities at base. T II 0.9 × as long as maximum width. Ovipositor longer than half length of fore wing, its sheath 1.15–1.25 (HT: 1.25) × as long as hind tibia.Apex of ovipositor as Fig. 3C View Fig .
Colouration ( Figs 6 View Fig D-H). Body (excluding wings and legs) black to blackish brown, except for: clypeus, malar space, frontal orbit and palpi yellowish brown; metasoma except for base of T I orange; ovipositor reddish brown. Wings hyaline, more or less darkened. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: tibial spurs, fore and mid tibiae and hind tarsus more or less tinged with yellowish brown.
Male (n=5). Similar to female ( Figs 6I, J View Fig ). Body length 8.0– 10.5 mm. Clypeus 0.53–0.56 × as long as maximum wide. Face 0.55–0.59 × as long as maximum wide. OD: POL: OOL = 1.0: 1.5–1.8: 1.2–1.4. Flagellum with 36–40 segments, with tyloid from FL 15 to FL 19 or 20. FL I 3.3 × as long as maximum depth in lateral view, 1.5 × as long as FL II. Fore wing 6.0– 7.3 mm. Hind femur 5.6–5.8 × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 3.8: 2.0: 1.4–1.5: 0.7: 1.05–1.1. T I 3.7–3.9 × as long as maximum width. T II 1.48–2.2 × as long as maximum width. Antenna without a white area. Face except for a pair of longitudinal black stripes below antennal sockets, clypeus except for dorsal and lateral margins, malar space and mandible except for apex largely yellow. Vertex with a pair of narrow yellow stripes along inner margin of eye. Tegula whitish yellow. Apex of metasoma blackish brown. Hind TS II to TS IV white to whitish yellow.
Distribution. Japan (Hokkaido).
Etymology. The species name is from the orange (Japanese term, daidai) coloration of metasomal tergites (gaster).
Remarks. This species resembles Cr. praefortis praefortis Rossem, 1990 in some character states especially coloration but it can be distinguished by the ovipositor longer than half length of fore wing (0.44–0.47 in Cr. praefortis praefortis ) and the propodeum without strongly projecting apophysis (with it in Cr. praefortis praefortis ). This species also resembles Cr. dianae in some character states but it can be distinguished by the antenna without white band in both sexes (with white band in female of Cr. dianae ), the hind femur blackish brown (reddish brown in Cr. dianae ), the face of male with a median yellow marking (without it in male of Cr. dianae ) and the tegula of male whitish yellow (largely black in male of Cr. dianae ).
