Antenna mainly dark reddish brown to black, two or several basal segments brownish yellow or light reddish brown, several basal flagellar segments usually reddish brown. Palpi yellow or pale yellow. Tegula light brown to almost yellow. Legs yellow to brownish yellow, hind tibia (at least in posterior half) and hind tarsus (rarely only basitarsus) brown, hind tibia basally yellow. Fore wing almost hyaline; veins brown to dark brown. Pterostigma dark brown, pale basally and apically.

Male. Body length 2.5–2.7 mm; fore wing length 2.5–2.9 mm. Antenna 39-segmented, about 2.0 × longer than body. Pterostigma weakly thickened. Metasoma narrow, 2.3–2.5 × longer than its maximum width, its apical segments weakly protruding behind third tergite. Length of first tergite 1.1–1.2 × its apical width, its dorsal carinae sometimes not fused. Sometimes mesosoma mainly dark. Otherwise similar to female.

Distribution. Russia: Primorskiy Territory, *Evreyskaya Autonomous Province, *Amur Province. Comparative diagnosis. This species is very similar to H. sutchanica Belokobylskij, 1992 ; the differences between these species are listed after redescription of the last species and in the key.
