Description. Female (n=2). Body covered with silver setae, length 10.0–10.5 (HT: 10.0) mm.
Head 0.56–0.57 (HT: 0.57) × as long as wide, densely and finely punctate. Clypeus polished, punctate, 0.56–0.59 (HT: 0.59) × as long as maximum wide, almost flat in lateral view, its apical margin with a median obtuse tooth and a pair of lateral weak convexities (Fig. 1G). Face 0.44 × as long as maximum wide, finely coriaceous laterally, reticulate rugose medially. Frons reticulate rugose except for a narrow smooth area above antennal sockets. Length of malar space 0.7–0.75 (HT: 0.7) × as long as basal mandibular width. Base of mandible slightly convex. Upper tooth of mandible as long as lower tooth. OD: POL: OOL = 1.0: 1.8: 2.4–2.5 (HT: 2.5). Flagellum with 26 segments. FL I 7.5 × as long as maximum depth in lateral view and 1.07–1.15 (HT: 1.15) × as long as FL II.
Mesosoma polished, length 1.73 × as long as maximum height in lateral view. Lateral aspect of pronotum reticulate rugose dorsally, longitudinally strigose ventrally. Epomia present. Posterior end of notauli reached to middle of mesoscutum. Mesoscutum densely punctate. Scutellum punctate. Mesopleuron largely rugose, with a smooth area on speculum. Mesosternum with the short median portion of posterior transverse carina. Metapleuron reticulate rugose. Juxtacoxal carina present, weak. Propodeum punctate on area externa and strongly reticulate rugose on areas behind anterior transverse carina. Anterior section of lateromedian longitudinal carina present basally. Anterior transverse carina complete (Fig. 2H). Posterior transverse carina complete except for median part absent (Fig. 2H). Pleural carina present anterior section, absent posterior section. Propodeal spiracle oval. Area basalis wider than long, its sides subparallel or slightly widened anteriorly (Fig. 2H). Fore wing length 7.3–8.0 (HT: 8.0) mm. Areolet vein 2rs-m and vein 3rs-m weakly convergent anteriorly (Fig. 11B). Distance from vein 2rs-m to vein 2m-cu shorter than distance from vein 2m-cu to vein 3rs-m (Fig. 11B). Hind wing vein 1-cu almost as long as cu-a. Fore tibia with a bulge in anterior 0.7. Hind femur 5.2–5.6 (HT: 5.2) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.0–4.2 (HT: 4.0): 2.0: 1.2: 0.7: 1.35–1.4 (HT: 1.4).
Metasoma dull, largely finely coriaceous. T I 2.2–2.3 (HT: 2.2) × as long as maximum width, polished, sparsely punctate, with latero-median carina except for posterior part, with dorso-lateral carina, without a pair of small convexities at base. T II 0.9 × as long as maximum width, densely and finely punctate. Ovipositor straight, its sheath 1.68–1.69 (HT: 1.68) × as long as hind tibia. Apex of ovipositor as Fig. 3J.
Colouration (Figs 11 A-D). Body (excluding wings and legs) black to blackish brown, except for: mandible partly tinged with reddish brown; FL VI or FL VII to FL IX white except for outer surface; posterior margin of each metasomal tergite narrowly tinged with reddish brown; a median spot of T VII and T VIII white to whitish yellow; ovipositor reddish brown. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown except for: fore tibia more or less tinged with reddish brown. Apex of scutellum sometimes narrowly tinged with yellow.
Male. Unknown.
Distribution. Japan (Honshu).
Etymology. The species name is from Japan.
Remarks. This species resembles Ho. scorteus in body structures and coloration, but it can easily be distinguished by the ovipositor sheath 1.68–1.69 × as long as hind tibia (0.9–0.95 in Ho. scorteus). This species also resembles Ho. intermedius sp. nov., but it can easily be separable by some characters (see Remarks of Ho. intermedius sp. nov.).
