Description. Female (n=2). Body covered with silver setae, length 8.1–8.6 (HT: 8.6) mm.
Head 0.58 × as long as wide, finely coriaceous. Clypeus polished, sparsely punctate, 0.6–0.67 (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 (Fig. 1E). Face 0.5 × as long as maximum wide, punctate. Frons punctate, covered with rugae on anterior to median ocelli. Length of malar space 0.9–1.0 (HT: 0.9) × 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: 1.7: 1.6. Flagellum with 27 segments. FL I 5.0 × as long as maximum depth in lateral view and 1.07 × as long as FL II.
Mesosoma polished, length 1.65 × as long as maximum height in lateral view. Lateral aspect of pronotum reticulate rugose dorsally, longitudinally strigose ventrally. Epomia short. Posterior end of notauli reached to middle of mesoscutum. Mesoscutum and scutellum punctate. Mesopleuron largely rugose, with a smooth area on speculum. Mesosternum with the short median portion of posterior transverse carina. Metapleuron reticulate rugose dorsally and obliquely rugose ventrally. Juxtacoxal carina present only near anterior end. Propodeum punctate and reticulate rugose. Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete (Fig. 9I). Posterior transverse carina present except for median part absent. Pleural carina complete. Propodeal spiracle rounded. Area basalis widened anteriorly. Fore wing length 5.9–6.2 (HT: 6.2) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m weakly convergent anteriorly (Fig. 9J). Distance from vein 2rs-m to vein 2m-cu slightly longer than distance from vein 2m-cu to vein 3rs-m (Fig. 9J). 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 4.7–5.2 (HT: 4.7) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.1–4.3 (HT: 4.3): 2.0: 1.35–1.45 (HT: 1.45): 0.8: 1.4.
Metasoma. T I 1.8–2.05 (HT: 1.8) × as long as maximum width, largely smooth, with a few, sparse punctures, with basal part of latero-median carina, with basal part of dorso-lateral carina present, without a pair of small convexities at base. T II 0.7–0.73 (HT: 0.73) × as long as maximum width. T II, T III and T IV matt, covered with fine, small punctures. Ovipositor straight, its sheath 0.95 × as long as hind tibia. Apex of ovipositor as Fig. 3G.
Colouration (Figs 9 F-J). 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 to FL IX white except for outer surface; T II and T III red; posterior margin of T I, T III to T V narrowly tinged with reddish brown; a median spot of T VII white; ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: apex of trochantelli and base of femora more or less narrowly tinged with red; fore and mid tibiae, tibial spurs and tarsi partly tinged with brown to yellowish brown; base of hind tibia whitish yellow; hind tarsus yellowish brown to reddish brown.
Male. Unknown.
Distribution. Japan (Hokkaido).
Etymology. The species name is from the type locality, Ashoro.
Remarks. This species resembles Ho. coxator (Tschek, 1871) in body structures and colouration, but it can be distinguished by the scutellum black (with a white marking in Ho. coxator), the hind femur blackish brown (red in Ho. coxator), the hind coxa black (sometimes red in Ho. coxator), the flagellum with 27 segments (21–23 in Ho. coxator) and the hind femur 4.7 × as long as maximum depth (4.9–5.6 in Ho. coxator).
