Redescription. FEMALE (holotype of O. novickyi , and non-type specimens). Body length 1100–1240 µm [ Soyka (1950) indicated the length of the holotype of O. novickyi as 1.67 mm but that is certainly incorrect because the length of its mesosoma and metasoma together is just 1045 µm; it is impossible to measure the length of the head because of the way it is mounted, but it would be safe to estimate (considering the average median head length in dorsal view in other conspecific specimens) that its total body length was a little more than 1.2 mm, perhaps 1210–1230 µm]. Head and mesosoma dark brown except eyes and ocelli pale or dirty pink; petiole yellowish to light brown; gaster mostly light brown (sometimes with a little darker on distal terga); scape and pedicel mostly light brown, flagellum brown to dark brown (F1 a little lighter); coxae and trochanters yellowish, remainder of leg segments light brown except distal tarsomeres darker.

Vertex and lower face with reticulate sculpture.

Antenna ( Figs 50, 52 ) with radicle 0.21–0.27x length of scape, remainder of scape 4.2–4.8x as long as wide, a little wider medially than basally or apically, longitudinally striate; pedicel longer than F1; all funicle segments longer than wide, more or less subequal in length (F1 the shortest and F5 the longest funicle segment), F1–F3 without mps, F4–F8 each with 2 mps; clava 2.6–2.9x as long as wide, a little shorter than scape plus radicle, about as long or slightly longer than combined length of F6–F8 and a little longer than combined length of F1–F3, with 7 mps.

Mesosoma ( Fig. 53 ) with pronotum weakly sculptured; mesoscutum and scutellum with reticulate sculpture (the cells smaller and less conspicuous on anterior scutellum; on posterior scutellum, the cells in the middle not as elongate as on the sides); metanotum smooth, with posterior margin broadly rounded; propodeum ( Fig. 54 ) mostly smooth, with median carina shorter than median areole; lateral carinae subparallel, extending to anterior margin of propodeum.

Forewing ( Figs 51, 55 ) usually 3.2–3.4x as long as wide (2.6 and 3.0x as long as wide in two specimens from Gornotayozhnoye , Primorskiy Kray, Russia, respectively); disc with a very slight brownish tinge throughout (almost hyaline), densely setose but bare behind base of submarginal vein, rounded (in specimens with relatively narrower forewings) or very slightly truncate (in specimens with relatively wider forewings) apically; longest marginal seta 0.14–0.17x greatest width of wing. Hind wing ( Fig. 56 ) 15–18x as long as wide; disc with a very slight brownish tinge (almost hyaline) and setose throughout (setae sparser behind apex of venation); longest marginal seta 1.8–2.3x greatest width of wing .

Coxae almost smooth (metacoxa very weakly sculptured); metafemur with weak sculpture.

Gaster longer than mesosoma; petiole 2.9–3.3x as long as wide, smooth, 1.0–1.2x as long as metacoxa; ovipositor occupying 0.8–0.9x length of gaster, at most slightly (by less than 0.1x own length) exserted beyond apex of gaster, 1.1–1.2x length of metatibia.

Measurements (µm) of the holotype of O. novickyi . Mesosoma: 424; petiole: 124; gaster: 545; ovipositor: 424. Antenna: pedicel: 55; F1: 42; F2: 45; F3: 45; F4: 50; F5: 54; F6: 50; F7: 48; F8: 46; clava: 153. Forewing: 1033:306; longest marginal seta: 49. Hind wing: 770:45; longest marginal seta: 81. Legs (given as coxa, femur, tibia, tarsus): fore: 106, 227, 239, 233; middle: 100, 236, 342, 245; hind: 136, 270, 397, 258.

MALE. Unknown.

Diagnosis. Ooctonus novickyi , known from females only, can be confused with O. insignis Haliday , whose female antenna also usually has 2 mps on F4–F8, but the pedicel of the latter is usually at least slightly shorter than F1 and the clava bears 8 mps. The gaster of O. insignis is usually dark brown (but sometimes brown) whereas it is notably lighter (mostly light brown) in O. novickyi .

Distribution. PALAEARCTIC: Austria, Bulgaria ( Donev 1990a [as O. flaviventris ]), Kyrgyzstan *, Poland *, Romania, Russia *, Sweden *, and Switzerland *.

Hosts. Unknown.
