Description. Female (n=1). Body covered with silver setae, length 8.3 mm.
Head 0.61 × as long as wide, polished, punctate. Clypeus 0.56 × as long as maximum wide, with a smooth area along apical margin, slightly convex in lateral view, its apical margin with a median obtuse tooth and a pair of lateral weak convexities (Fig. 1I). Face 0.56 × as long as maximum wide, densely punctate, granulate. Frons largely reticulate rugose, with a weak median longitudinal carina. Length of malar space 0.75 × as long as basal mandibular width. Base of mandible almost flat. Upper tooth of mandible almost as long as lower tooth. OD: POL: OOL = 1.0: 1.1: 1.5. Flagellum with 25 segments. FL I 8.6 × as long as maximum depth in lateral view and 1.15 × 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 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 complete. Propodeum punctate on area externa and strongly reticulate rugose on areas behind anterior transverse carina. Anterior section of lateromedian longitudinal carina present. Anterior transverse carina complete (Fig. 13G). Posterior transverse carina complete (Fig. 13G). Pleural carina complete except for a small interruption of posterior section. Propodeal spiracle oval. Area basalis wider than long, widened anteriorly. Fore wing length 5.6 mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m weakly convergent anteriorly (Fig. 13H). Distance from vein 2rs-m to vein 2m-cu shorter than distance from vein 2m-cu to vein 3rs-m (Fig. 13H). Nervellus of hind wing intercepted below the middle by second abscissa of vein Cu (Fig. 13). Apical 0.7 of fore tibia swollen. Hind femur 5.0 × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.4: 2.0: 1.2: 0.7: 1.4.
Metasoma polished. T I 2.2 × as long as maximum width, sparsely punctate, with latero-median carina except for posterior part absent, dorso-lateral carina and a pair of small convexities at base. T II 0.85 × as long as maximum width. T II, T III and T IV covered with dense punctures except for posterior margin. Ovipositor straight, its sheath 0.95 × as long as hind tibia. Apex of ovipositor as Fig. 3M.
Colouration (Figs 13 D-I). Body (excluding wings and legs) black to blackish brown, except for: mandible partly tinged with reddish brown; FL VI to FL IX white except for outer surface; humeral plate yellowish brown; scutellum with a conspicuous yellow marking (its ca. apical 0.7 of scutellum); T I reddish brown except for base; thyridium and ovipositor reddish brown; posterior margin of metasomal tergites narrowly tinged with reddish brown; membranous part of metasoma and a median spot of T VII and T VIII white. Wings hyaline. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: fore and mid legs except for coxae and trochanters more or less tinged with yellowish brown; apex of hind trochantellus and base of hind femur narrowly tinged with reddish brown; base of hind tibia and hind tibial spurs yellowish brown.
Male. Unknown.
Distribution. Japan (Toshima Is.).
Etymology. The species name is from the type locality, Toshima Island.
Remarks. This species resembles Ho. pini but it can be distinguished by the scutellum with a conspicuous yellow marking (entirely black in Ho. pini), the metapleuron and propodeum black (red to reddish brown in Ho. pini) and the malar space 0.75 × as long as basal mandibular width (more than 0.9 × as long as basal mandibular width in Ho. pini).
