FL I 6.7–7.5 (HT: 6.7) × as long as maximum depth in lateral view and 1.07–1.11 (HT: 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 present. Posterior end of notauli reached to middle of mesoscutum. Mesoscutum and scutellum densely punctate. Mesopleuron largely reticulate rugose, with a smooth area on speculum. Mesosternum with the short median portion of posterior transverse carina. Metapleuron reticulate rugose. Juxtacoxal carina absent. 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. 2G). Posterior transverse carina largely absent except for a pair of short sublateral sections ( Fig. 2G). Pleural carina present anterior section, absent posterior section ( Fig. 2G). Propodeal spiracle oval. Area basalis wider than long, widened anteriorly. Fore wing length 7.5–8.5 (HT: 8.5) mm. Areolet pentagonal, vein 2rs-m and vein 3rs-m slightly convergent anteriorly or subparallel ( Fig. 10K). Distance from vein 2rs-m to vein 2m-cu shorter than distance from vein 2m-cu to vein 3rs-m ( Fig. 10K). Nervellus of hind wing intercepted at the middle by second abscissa of vein Cu. Fore tibia with a bulge in anterior 0.7. Hind femur 5.5–5.7 (HT: 5.7) × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 4.3–4.5 (HT: 4.5): 2.0: 1.2–1.35 (HT: 1.35): 0.65–0.7 (HT: 0.7): 1.25–1.35 (HT: 1.25).

Metasoma dull, finely coriaceous. T I 2.0–2.2 (HT: 2.0) × as long as maximum width, polished, with sparse punctures, with latero-median carina and dorso-lateral carina, without a pair of small convexities at base. T II 0.75–0.8 (HT: 0.8) × as long as maximum width. T II and T III densely punctate except for posterior margin. Ovipositor slightly upcurved, its sheath 1.58–1.75 (HT: 1.58) × as long as hind tibia. Apex of ovipositor as Fig. 3I.

Colouration ( Figs 10 G-K). Body (excluding wings and legs) black to blackish brown, except for: mandible partly slightly tinged with reddish brown; FL VI or FL VII to FL IX white except for outer surface; a median spot of T VII and T VIII white; 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 (n=1). Similar to female. Face 0.53 × as long as maximum wide. Length of malar space 0.7 × as long as basal mandibular width. Flagellum with 29 segments, with tyloid from FL 13 to FL 17. FL I 5.0 × as long as maximum depth in lateral view, 1.5 × as long as FL II. Posterior transverse carina of propodeum complete. Fore wing 6.4 mm. Hind femur 5.9 × as long as maximum depth in lateral view. Hind TS I: II: III: IV: V = 3.75: 2.0: 1.4: 0.7: 0.9. T I 6.2 × as long as maximum width. T II 2.05 × as long as maximum width. Antenna without a white area. Face with a pair of lateral yellow spots and a median yellow spot. Palpi whitish yellow. Fore and mid femora, tibiae and tarsi largely reddish or yellowish brown. Base of hind tibia with a conspicuous white band. Hind TS II, TS III, TS IV and base of TS V white.

Distribution. Japan (Hokkaido and Honshu).

Etymology. The species name is from the character states of this species, which is more or less intermediate condition between Agrothereutes and Hoplocryptus .

Remarks. This species resembles Ho. savioi Uchida, 1940 in the body covered with dense punctures, but it can be distinguished by the nervellus of hind wing intercepted at the middle by second abscissa of vein Cu (intercepted above the middle in Ho. savioi ) and the ovipositor distinctly longer than T I (slightly longer than T I in Ho. savioi ). This species also resembles Ho. japonicus sp. nov., but it can easily be distinguished by the ovipositor slightly upcurved (straight in Ho. japonicus ) and the length of mesosoma 1.65 × as long as maximum height in lateral view (1.73 in Ho. japonicus ).
