Description. FEMALE. Body length (dry-mounted paratypes) 960–1190 µm. Head and mesosoma mostly dark brown with some brown; radicle yellowish, scape and pedicel light brown to brown, flagellum dark brown; gaster yellow or light brown basally and brown to dark brown apically; legs light brown to brown.

Antenna ( Fig. 28 ) with radicle 3.4–4.0× as long as wide, 0.34–0.39× total length of scape, rest of scape finely longitudinally striate, 2.8–3.1× as long as wide; pedicel at least slightly longer than F1; F1 shorter than F2 (usually the longest funicle segment), F3 as long as or almost as long as F2, F4 about as long as F5, F6 normally the shortest funicle segment (when lacking mps) or almost as long as F4 (when bearing a mps), F7 as long as F8, mps on F5 (1), F6 (usually 0, occasionally 1 on one antenna), F7 (2), and F8 (2); clava with 8 mps, 3.6–4.5× as long as wide, at least slightly longer than combined length of F6–F8.

Mesosoma ( Fig. 29 ). Propodeum with submedian lines fine, incomplete, usually barely visible. Fore wing ( Fig. 30 ) 3.9–4.1× as long as wide; longest marginal seta 0.38–0.4× maximum wing width. Fore wing disc slightly infumate throughout, mostly bare behind submarginal vein (except for a few setae behind its apex) and setose elsewhere. Hind wing ( Fig. 31 ) 26–29× as long as wide; disc bare except for rows of setae along margins and a few additional, scattered setae, slightly infumate; longest marginal seta about 3.5–4.0× maximum wing width.

Metasoma ( Fig. 29 ). Gaster longer than mesosoma. Petiole short, trapezoidal. Ovipositor 0.7–0.8× length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 1.3–1.4:1.

Measurements (µm) of the holotype. Mesosoma 443; petiole 30; gaster 615; ovipositor 473. Antenna: radicle 73; rest of scape 113; pedicel 69; F1 52; F2 70; F3 68; F4 55; F5 55; F6 48; F7 61; F8 61; clava 219. Fore wing 1323:326; longest marginal seta 124. Hind wing 1039:39; longest marginal seta 139.

MALE. Unknown.

Diagnosis. Gonatocerus koziavka is most similar to G. cincticipitis from which it differs by the female characters indicated in the key, and also by the larger body size.

Etymology. The species name is a noun in apposition meaning “a bug ” in Russian.

Hosts. Unknown.
