Description. Female (n=19). Body covered with silver setae, length 6.2–11.3 (HT: 7.7) mm.
Head 0.57 × as long as wide, polished, finely punctate. Clypeus sparsely punctate except for smooth apical area, 0.56–0.61 (HT: 0.56) × 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. 1H). Face 0.48–0.5 (HT: 0.5) × as long as maximum wide, finely coriaceous. Frons finely coriaceous except for a narrow smooth area above antennal sockets. Length of malar space 1.0–1.05 (HT: 1.0) × 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: 1.3–1.7 (HT: 1.7): 1.6–1.89 (HT: 1.6). Flagellum with 20–22 (HT: 20) segments. FL I 7.5 × as long as maximum depth in lateral view and 1.0 × as long as FL II.
Mesosoma polished, length 1.65 × as long as maximum height in lateral view. Lateral aspect of pronotum longitudinally strigose except for narrow dorsal area reticulate rugose. Epomia weak. 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 covered with irregular and/or oblique rugae. Juxtacoxal carina present anteriorly. Propodeum punctate on area externa and strongly reticulate rugose on areas behind anterior transverse carina. Anterior section of lateromedian longitudinal carina present, its posterior ends sometimes confluent (Figs 2 I-K). Anterior transverse carina complete (Figs 2I, 11H). Posterior transverse carina complete (Figs 2I, 11H). Pleural carina complete (Fig. 2I). Propodeal spiracle rounded. Area basalis longer than wide, widened anteriorly (Fig. 2I). Fore wing length 5.4–8.6 (HT: 5.9) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m convergent anteriorly (Fig. 11I). Distance from vein 2rs-m to vein 2m-cu almost as long as distance from vein 2m-cu to vein 3rs-m (Fig. 11I). 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 5.1–5.7 (HT: 5.7) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.4–4.8 (HT: 4.8): 2.0: 1.2: 0.6: 1.25–1.3 (HT: 1.3).
Metasoma dull, densely coriaceous. T I 1.9–2.3 (HT: 2.2) × as long as maximum width, with sparse punctures, with latero-median carina and dorso-lateral carina, without a pair of small convexities at base. T II 0.75–0.95 (HT: 0.95) × as long as maximum width. Ovipositor straight, its sheath 1.06–1.18 (HT: 1.08) × as long as hind tibia. Apex of ovipositor as Fig. 3K.
Colouration (Figs 11 E-I). 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; humeral plate and membranous parts of metasoma white to whitish yellow; posterior margin of each metasomal tergite narrowly tinged with dark reddish brown; ovipositor reddish brown. Wings hyaline, with a large, conspicuous longitudinal clouded area posterior to pterostigma. Veins and pterostigma blackish brown to brown. Legs black to blackish brown, except for: base of femora more or less narrowly tinged with red; fore femora and tibiae more or less tinged with yellowish brown; hind TS II, TS III and base of TS IV white.
Distribution. Japan (Honshu and Sado Is.).
Etymology. The species name is from a pigmented blackish marking of fore wing.
Remarks. This species resembles Ho. alboanalis, but it can be distinguished by the fore wing with a broad, conspicuous clouded band posterior to pterostigma (without any clouded band in Ho. alboanalis) and the ovipositor sheath 1.06–1.18 × as long as hind tibia (ca. 1.0 in Ho. alboanalis). This species also apparently resembles Nippocryptus vittatorius (Jurine, 1807) in the black body and the fore wing with a conspicuous clouded band, but it can be distinguished by the generic diagnose and the hind tarsus with a white area (without a white band in N. vittatorius).
