Mesoscutum and scutellum entirely smooth, mesoscutum rugose laterally and anteriorly along its margins, punctate anteriorly on median lobe. Mesopleuron mainly smooth. Propodeum entirely or almost entirely coarsely and densely rugose-areolate with sparse transverse striation, sometimes almost smooth basally, without delineated areola, with distinct carina in mediobasal 0.3. First tergite entirely weakly curvedly or almost linearly and sparsely striate with dense rugulosity, sometimes rugosereticulate medially; second tergite dense or very densely and rather finely striate with reticulation; third tergite almost entirely and rather finely rugulose-reticulate with densely oblique striation at least partly or entirely, almost smooth on narrow or wide posterior margin and laterally. Vertex widely glabrous, with sparse setae laterally, sometimes partly and sparsely setose medially. Mesosoma glabrous, with sparse short setae along notauli and laterally.

Colour. Head brownish yellow, yellowish brown or reddish brown, darker dorsally. Mesosoma dark reddish brown and partly reddish brown, reddish in some spots. Metasoma reddish brown or dark reddish brown, third tergite sometimes faintly paler. Antenna mainly dark reddish brown to almost black, two-three basal segments yellow. Palpi yellow to pale yellow apically. Tegula light brown or light reddish brown. Legs yellow to brownish yellow, hind tibia and tarsus brown, but hind tibia basally yellow or yellowish. Fore wing faintly or very faintly infuscate; veins brown or dark brown. Pterostigma brown, faintly paler basally and apically.

Male. Body length 2.1–2.8 mm; fore wing length 2.2–3.0 mm. Antenna 41-segmented, 1.8–2.0 × longer than body. Pterostigma weakly thickened. Metasoma narrow, its apical segments more or less distinctly protruding behind third tergite, 2.4–2.7 × longer than its maximum width. Length of first tergite 1.1–1.2 × its apical width. Sometimes body darker. Otherwise similar to female.

Distribution. Russia (Primorskiy Territory, *Amur Province), North Korea.

Comparative diagnosis. This species is similar to H. hymaenei Belokobylskij , but differs from it in having the notauli developed only in the anterior third of mesoscutum, median mesoscutal depression short, metasoma narrow, first metasomal tergites weakly widened apically, second and third tergites narrow, finely and densely striate with reticulation, and body mainly dark reddish brown (see also key to species below).

Remarks. Study and direct comparison of the type material of H. sutchanica and H. adsimilis distinctly showed their affiliation to single species (syn. nov.). Previously listed differences between these forms (see: Papp, 1994; Belokobylskij, 1998; Fischer, 2008) were results of the interspecies variability of some features or unclear their designations in the original description of H. adsimilis .
