Description. Female (n=6). Body covered with silver setae, length 7.6–8.4 (HT: 8.2) mm.
Head 0.57–0.59 (HT: 0.57) × as long as wide, finely coriaceous. Clypeus sparsely punctate, 0.59–0.67 (HT: 0.67) × as long as maximum wide, slightly convex in lateral view, its apical margin with a median obtuse tooth and a pair of lateral weak convexities. Face 0.48–0.5 (HT: 0.48) × as long as maximum wide, finely coriaceous, partly finely punctate. Frons finely coriaceous, with some transverse rugae above antennal sockets. Vertex finely punctate. Length of malar space 0.8–0.9 (HT: 0.85) × as long as basal mandibular width. Base of mandible slightly convex. Upper tooth of mandible almost as long as lower tooth. OD: POL: OOL = 1.0: 1.2–1.25 (HT: 1.25): 1.6–1.8 (HT: 1.75). Flagellum with 21–23 (HT: 23) segments. FL I 7.5 × as long as maximum depth in lateral view and 1.02–1.03 (HT: 1.03) × as long as FL II.
Mesosoma polished, length 1.65 × as long as maximum height in lateral view. Lateral aspect of pronotum rugose dorsally, longitudinally strigose ventrally. Epomia present. Posterior end of notauli reached to middle of mesoscutum. Mesoscutum granulate, densely and finely punctate. Scutellum punctate. Mesopleuron finely coriaceous, partly rugose, with a smooth area on speculum. Mesosternum with the short median portion of posterior transverse carina. Metapleuron reticulate rugose. Juxtacoxal carina absent (Fig. 2F). Propodeum finely coriaceous on area externa, reticulate rugose on areas behind anterior transverse carina. Maximum width of propodeum 0.92–1.0 (HT: 1.0) × as long as median length of propodeum in dorsal view. Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete. Posterior transverse carina complete (Fig. 2F). Pleural carina present but partly obsolete on posterior section (Fig. 2F). Propodeal spiracle oval. Area basalis longer than wide, widened anteriorly. Fore wing length 5.7–6.9 (HT: 6.9) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m more or less convergent anteriorly (Fig. 10F). Distance from vein 2rs-m to vein 2m-cu shorter than distance from vein 2m-cu to vein 3rs-m (Fig. 10F). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu. Fore tibia with a bulge in anterior 0.7. Hind femur 5.0–5.2 (HT: 5.1) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.5–4.7 (HT: 4.5): 2.0: 1.2–1.3 (HT: 1.2): 0.7–0.75 (HT: 0.75): 1.7.
Metasoma dull. T I 1.9–2.1 (HT: 2.0) × as long as maximum width, polished, largely finely coriaceous, with a few, sparse punctures, with latero-median carina and dorso-lateral carina, without a pair of small convexities at base. T II 0.85–0.95 (HT: 0.88) × as long as maximum width. T II, T III and T IV finely coriaceous and finely punctate. Ovipositor straight, its sheath 0.88–1.0 (HT: 0.95) × as long as hind tibia. Apex of ovipositor as Fig. 3H.
Colouration (Figs 10 A-F). Body (excluding wings and legs) black to blackish brown, except for: mandible partly slightly tinged with reddish brown; humeral plate and membranous parts of metasomal sternites yellowish brown; FL V or FL VI to FL VIII or FL IX white except for ventral surface; posterior margin of each metasomal tergites narrowly tinged with reddish brown; a median spot of T VI and T VII white; ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: base of femora more or less narrowly tinged with red; base of mid and hind tarsal segments narrowly tinged with yellowish brown. Posterior part of T I, T II and T III sometimes red.
Male. Unknown.
Distribution. Japan (Hokkaido and Honshu).
Etymology. The species name is from the old name of Hokkaido, Ezo.
Remarks. This species resembles Ho. alboanalis and Ho. scorteus but it can be distinguished by the propodeum wide, its maximum width 0.92–1.0 × as long as its median length in dorsal view (0.8 in Ho. alboanalis), the lateral sides of area basalis widened anteriorly (subparallel in Ho. alboanalis), the metasomal tergites sometimes partly tinged with red (without conspicuous red area except for posterior margin of T II in Ho. alboanalis and Ho. scorteus), the vein 2rs-m and vein 3rs-m of areolet convergent anteriorly (subparallel in Ho. scorteus) and the nervellus of hind wing intercepted below the middle by second abscissa of vein Cu (at the middle in Ho. scorteus).
