( Figs 25–31 )

Spaniopus hedqvisti Huggert, 1976: 62 –64; holotype ♂ (NHRS, not examined). Type locality: [ Sweden] “Hällnäs”.

Description. Female. Body length 1.6–2.2 mm; fore wing length 0.9–1.5 mm. Colour: head, mesosoma dark metallic green or dark metallic blue to blush-green or blush-purple often with diffuse coppery lustre; metasoma dark metallic green; scape basally yellowish-brown, apically brown, pedicel and flagellum brown; legs yellowishbrown, last segment of tarsi brown; fore wing with light brownish tint; ovipositor sheath dark brown.

Head in dorsal view 2.1–2.2× as broad as long and 1.2–1.3× as broad as mesoscutum; in frontal view 1.2–1.3× broader than high. POL 1.3–1.5× OOL. Eye height 1.5× eye length and 1.5× as long as malar space. Frons 1.3× broader than eye height. Distance between antennal toruli and lower margin of clypeus 0.8× as long as distance between antennal toruli and median ocellus. Clypeus radially striate, its lower margin weakly emarginate. Antenna with scape 0.9× as long as eye height and 1.3× as long as eye length; pedicel 1.9–2.0× as long as broad and 1.5– 1.6× as long as F1; combined length of pedicel and flagellum 0.9× breadth of head; second anellus of antenna transverse and 1.5–1.6× as long as first one; flagellum slightly clavate; F1 1.3–1.5× as long as broad, hardly constricted basally; F2, F3 subquadrate, F4–F6 subtransverse; each funicular segment with one row of dense sensilla; clava 1.7× as long as broad.

Mesosoma 1.50–1.55× as long as broad. Pronotal collar medially 0.27× as long as mesoscutum. Scutellum finely reticulate, about as long as broad, with noticeable but shallow frenal line. Propodeum medially 0.66× as long as scutellum; with median carina complete and irregular, costula absent; nucha subglobose and strongly reticulate, occupying 0.5–0.6× length of propodeum. Fore wing 2.4–2.6× as long as maximum width; basal cell hairy; speculum open, cubital vein with several hairs; M 1.3–1.4× as long as P and 1.3–1.4× as long as S; P as long as S.

Metasoma ovate-acuminate, 1.4–1.6× as long as broad and 1.4× as long as mesosoma. Ovipositor sheath projecting slightly beyond apex of metasoma.

Male. Body length 1.2–1.5 mm. Colour: head, mesosoma and metasoma metallic green with diffuse coppery lustre; scape, F1, F2, F5 and F6 yellow, pedicel, F3, F4 and clava brown. Head in dorsal view 1.4–1.5× as broad as mesoscutum. POL 1.50–1.55× OOL. Eye height 1.4× eye length and 2.3× as long as malar space. Combined length of pedicel and flagellum 1.1× breadth of head; clava 2.7× as long as broad. Mesosoma 1.75× as long as broad. Nucha occupying at most 0.3× length of propodeum. Inner margin of mid tibia with two flattened and brownish lobe. Otherwise similar to female.

Distribution. Sweden ( Huggert 1976; Noyes 2015).

Biology. Unknown.

Comparative diagnosis. Spaniopus hedqvisti is very similar to S. varicornis ; the differences between these species are shown in the respective keys to the sexes.

Comments. Females of S. hedqvisti vary in wing-size ( Fig. 26 ), and one studied specimen has three anelli and five funicle segments ( Fig. 26 ). Sexual dimorphism of this species includes colour of the antennae ( Fig. 29 ) as well as colour and shape of the mid tibiae ( Fig. 30 ).
