Holotype: 1 female (NMA), “Denmark, E-Jutland, Højen Bæk, 5 km S of Vejle, 07.07.1984, Munk”. Paratype: 1 female (NMA), same label as holotype, both specimens were collected in a deciduous wood with Alnus, Fraxinus and Fagus on wet ground, 07.07.1984; 1 female (ZSSM), “Italy, St. Peter/Ahrntal, Südtirol, 1600 m., Ja/26.08.1967, Haeselbarth”.
Holotype, female, Length of body 1.40–1.60 mm, of fore wing 2.20 mm.
Head. In dorsal view, 1.60 times as wide as its median length, 1.50 times as wide as mesoscutum, smooth, with rounded temples behind eye. Eye in lateral view 1.55 times as high as wide and 0.90–0.95 times as wide as temple. POL 2.75–2.80 times OD; OOL 3.40–3.45 times OD. Face 1.35 times as wide as high; inner margins of eyes subparallel. Clypeus 3.10 times as wide as high, slightly curved ventrally. Paraclypeal fovea large, its diameter more than half the distance between clypeus and eye. Mandible widened towards apex, 1.60 times as long as its maximum width. Upper tooth weakly shorter than middle tooth and wider than middle and lower tooth. Middle tooth the longest, widened basally and pointed apically. Lower tooth rounded apically and shorter than upper tooth. Antenna thick, 21-segmented, longer than body. Scape 2.00 times as long as pedicel. First flagellar segment 3.65–3.70 times as long as its apical width, 1.15 times as long as second segment; second segment 2.50 times as long as its maximum width. Third to eighteenth flagellar segments 2.20–2.30 times as long as their width; nineteenth segment 2.00 times as long as its maximum width.
Mesosoma. In lateral view, 1.10–1.15 times as long as high. Mesoscutum 1.10–1.15 times as long as maximum width with two rows of single setae. Notauli mainly absent. Mesoscutal pit present and elongated. Prescutellar depression smooth, without lateral carinae. Sternaulus (= precoxal suture) present, not reaching anterior and posterior parts of mesopleuron. Posterior mesopleural furrow smooth. Propodeum with median longitudinal carina running from anterior to posterior its margins, in anterior third with transverse angulated carina, with additional long subparallel carinae laterally to median one; from lateral carinae emerging short carinae not reaching propodeal edges. Propodeal spiracles relatively small.
Legs. Hind femur 4.50 times as long as wide. Hind tibia weakly widened to apex, 9.10–9.15 times as long as its maximum subapical width, as long as hind tarsus. First segment of hind tarsus 1.95–2.00 times as long as second segment.
Wings. Length of fore wing 2.50–2.60 times its maximum width. Vein r1 present. Radial cell reaching to apex of wing, 4.50 times as long as its maximum width. Nervulus distinctly postfurcal. Brachial cell closed, 3.00 times as long as its maximum width. Hind wing 8.0 times as long as its maximum width.
Metasoma. Distinctly compressed. First tergite weakly widened towards apex, 1.90 times as long as its apical width, almost sculptured with fine striae. Ovipositor 2.10 times as long as first tergite, as long as metasoma, 1.60–1.65 times as long as hind femur.
Colour. dark brown with a red tone, except propleuron, scapus, pedicellus and anterior half of metasoma infuscate reddish; clypeus and legs yellow (fifth tarsal segment infuscate).
The name is due to the large size of the ovipositor valves.
