Propodeum medially 0.6× as long as scutellum; with median carina complete, costula absent; nucha subglobose and reticulate, occupying at least 0.5× length of propodeum. Fore wing 2.2–2.4× as long as maximum width; basal cell of fore wing pilose; speculum open; M as long as P and 1.4–1.6× as long as S; P 1.4× as long as S.

Metasoma 1.9–2.0× as long as broad and 1.23× as long as mesosoma. Ovipositor sheath projecting slightly beyond apex of metasoma.

Male. Body length 2.5 mm. Colour: head, mesosoma and metasoma metallic green or metallic blue with diffuse coppery lustre; scape, pedicel, both anelli and F1 yellow, F2–F4 yellowish-brown, F5, F6 and clava brown; fore wing hyaline. POL 1.4× OOL. Combined length of pedicel and flagellum 1.1× breadth of head; flagellum slender, F1–F6 longer than broad. Metasoma 1.3× as long as broad and as long as mesosoma. Otherwise similar to the female.

Material examined. JAPAN: 1 ♀ (holotype), “Sapporo, Hokkaido, 24.V 1.1960, TAKAGI-S.”, “ Holotype Spaniopus sasacolae ♀ Kamijo”; 1 ♂ (paratype), “Iwamizawa, Hokkaido, 15.VII.1980, K. KAMIJO”, “ Paratype Spaniopus sasacolae ♂ Kamijo” (both from EIHU). RUSSIA *: 1 ♀, “Kuril Islands, Kunashir, Alekhino, 11–13.V 1973, Kerzhner” ( ZISP).

Distribution. Japan, Russia (South of Far East)*, ( Kamijo 1981; Noyes 2015).

Biology. Primary parasitoid of Hasegawaia sasacola Monzen, 1937 ( Diptera , Cecidomyiidae ) ( Kamijo 1981; Noyes 2015).

Comparative diagnosis. This species is similar to S. monospilus and S. fulvicornis ; the differences between the species are given in the respective keys to the sexes.
