description: Habrocampulum shikaribetsensis (Uchida, 1958) comb. nov.
[Japanese name: Shikaribetsu-kombô-amebachi] (Figs 1–6)
Aphanistes shikaribetsensis Uchida, 1958: 104. Holotype, female, Hokkaido, Japan (SEHU), by monotype.
Specimen examined. 1 female, Japan: Shikaribetsu, Hokkaido, 24. viii. 1934 (T. Uchida leg.) (holotype of Aphanistes shikaribetsensis) (SEHU).
Redescription of holotype. Female (n=1).
Head (Figs 2–4). Face 0.7 × as long as wide, moderately polished, entirely covered with dense punctures and hairs, subantennal area with two groups of radial striae (Fig. 2). Clypeus 0.6 × as long as wide, polished with sparse punctures and hairs, with a median apical tooth (Figs 2, 4). Malar space 0.2 × as long as basal width of mandible. Lower tooth of mandible distinctly shorter than upper one. Outer surface of mandible with a swelling and an oblique impression (Figs 2, 4). Frons areolate-rugose to densely punctate with a median longitudinal carina (Figs 2, 3). Occipital carina complete, its lower end reaching base of mandible (Figs 3, 4). OOD 1.3 × as long as LOD, IOD 1.4 × as long as LOD, POD 0.2 × as long as LOD (Fig. 3). Antenna with 47 flagellmeres. First flagellomere 4.6 × as long as its width and 2.2 × as long as second flagellomere.
Mesosoma (Figs 5, 6). Antero-ventral corner of pronotum with weak tooth (Fig. 5). Dorsal 0.3 of pronotum covered with punctures and hairs, central part transversally striate, in lateral view (Fig. 5). Anterior margin of mesoscutum with concavity (Fig. 5). Notauli present, its posterior end reaching posterior margin of mesoscutum (Fig. 5). Mesoscutum 1.3 × as long as its width in dorsal view, entirely evenly punctate except for its posteromedian part areolate-rugose. Scutellum punctate with hairs. Mesopleuron punctate and hairs, dorsal 0.3 punctaterugose and longitudinal punctate-strigose (Fig. 5). Epicneminal carina present. Metapleuron with oblique striae (Fig. 5). Postscutellum elongate, longer than its width (Fig. 6). Propodeum rounded in dorsal profile and slightly rounded in lateral profile (Fig. 5), its median part covered with transverse strigose and lateral part covered with the ladder-like furrow.
Wings. Fore wing 10.5 mm, with CI=0.9; BI =1.8; DBI=0.6; MI=1.6; ICI=1.4. Hind wing with 13 uniform hamuli and RI=1.4; NI=0.9.
Legs. Hind coxa elongated, 2.6 × as long as its width. Trochanter as long as trochantellus in ventral view. Hind femur 8.8 × as long as its width and 0.7 × as long as hind tibia. Hind basitarsus 2.3 × as long as second tarsus.
Metasoma. PI=4.0; DMI=1.7. Ovipositor sheath 0.5 × as long as hind tibia, tip of upper valve strongly tapered, and tip of lower valve carved downward.
Colouration (Fig. 1). Following parts amber: metasoma (except for dorsum of T2, T5, and T6), hind trochantellus, hind femur, proximal 0.6 of hind tibia, hind tarsus, fore and mid legs (except for mid coxa), venation of wing, apex of mandible, and antenna. Following parts black: mid and hind coxae, hind trochanter, distal 0.3 of hind tibia, dorsum of T2, T5, and T6, mesosoma (except for scutellum), frons, most of vertex and gena. Following parts yellow: face, clypeus, most of mandible, a part of vertex and gena, and scutellum.
Male. Unknown.
Distribution. Japan (Shikaribetsu, Hokkaido).
Bionomics. Unknown.
Remarks. This species can be easily distinguished from other anomalonine species recorded in Japan by the following combinations of characteristics: (1) eyes bare; (2) lower margin of clypeus with a median apical tooth (Figs 2, 4); (3) antero-ventral corner of pronotum with a tooth (Fig. 5); (4) mesoscutum rounded, and its anterior margin with a weak concavity (Fig. 5); (5) notauli present (Fig. 5); (6) postscutellum longer than its width (Fig. 6); and (7) fore coxa smooth.
Generic distribution. Habrocampulum has been previously recorded from the Nearctic and Western Palaearctic regions (Yu et al. 2012). Recognition of this genus from Japan is biogeographically and taxonomically important, extending the distribution into the Eastern Palaearctic region.
