Spaniopus belokobylskiji sp. nov.

( Figs 7–12 )

Description. Female. Body length 2.7–3.0 mm; fore wing length 2.2–2.4 mm. Colour: head, mesosoma and metasoma dark metallic green with diffuse coppery lustre; antenna with scape yellowish-brown, pedicel basally brown and apically yellowish-brown, flagellum brown; coxae brown, femora and tibiae yellowish-brown, and tarsi yellow except last segment brown; fore wing with dark broad spot under M and S, venation yellowish-brown; ovipositor sheath dark brown.

Head in dorsal view 2.1–2.2× as broad as long and 1.1–1.2× as broad as mesoscutum; in frontal view 1.25× broader than high. POL 1.1–1.2× OOL. Eye height 1.4× eye length and 1.6× as long as malar space. Frons 1.5× broader than eye height. Distance between antennal toruli and lower margin of clypeus 0.8× distance between antennal toruli and median ocellus. Clypeus radially striate, its lower margin weakly emarginate. Mandible formula 3:4. Antenna with scape as long as eye height and 1.4× as long as eye length, reaching to anterior edge of median ocellus; pedicel 1.6–1.8× as long as broad and as long as F1; combined length of pedicel and flagellum 0.8–0.9× breadth of head; anelli equal in length; flagellum almost filiform; F1 1.5× as long as broad and hardly constricted basally; F2–F5 longer than broad and F6 subquadrate; each funicular segment with one row of dense sensilla; clava 2.0–2.2× as long as broad.

Mesosoma 1.50–1.55× as long as broad. Pronotal collar medially 0.2× as long as mesoscutum. Scutellum finely reticulate, about as long as broad, with distinctly frenal line. Propodeum medially 0.70–0.75× as long as scutellum; with median carina complete and irregular, costula absent; nucha subglobose and strongly reticulate, occupying 0.5× length of propodeum. Fore wing 2.3× as long as maximum width; basal cell bare; speculum open; M as long as P and 1.2–1.25× as long as S; P 1.2–1.25× as long as S.

Metasoma ovate-acuminate, 1.5–1.6× as long as broad and 1.1× as long as mesosoma. Ovipositor sheath projecting slightly beyond apex of metasoma.

Male. Unknown.

Material examined. Holotype: ♀, RUSSIA, “Primorskiy Territory, near Vladivostok, 21.VII 1961, E. Shuvakhina” ( ZISP). Paratype: 1 ♀, RUSSIA, “Primorskiy Territory, 30 km SE Ussuriysk, 12–17.VII.2001, S. Belokobylskij” ( ZISP).

Distribution. Russia (South of Far East).

Biology. Unknown.

Etymology. Named in honour of the Russian hymenopterist, Dr. Sergey A. Belokobylskij.

Comparative diagnosis. Spaniopus belokobylskiji belongs to a group that includes most known species, in which females have as relative shorter F1 that is hardly constricted basally and the second anellus is distinctly transverse; differences from other species are shown in the key. Females are similar to those of S. fulvicornis and S. monospilus by the fore wing having a broad dark spot under M and S, but differ from females of both in having a shorter F1 and M as long as P.
