( Figs 8–11 View FIGURES 8 – 11 )

Type material. Holotype female [ CAS] on slide: RUSSIA. SAKHALINSKAYA OBLAST’, Sakhalin Island, ca. 6 km E of Sokol, 47 ° 15.08 ’N 142 ° 48.10 ’E, 12.viii. 2001, D.J. Bennett, T. Anderson, MT. Paratype female [ ZMUC] on slide: DENMARK. SJAELLAND, Zealand Island, Nyvang, 9.viii. 1946, O. Bakkendorf.

Description. FEMALE. Body length (paratype) 1200 µm. Head and mesosoma brown to dark brown; radicle yellowish, scape and pedicel light brown to brown, F 1 brown, remainder of flagellum dark brown; gaster and legs light brown to brown.

Antenna ( Fig. 8 View FIGURES 8 – 11 ) with radicle about 3.0× as long as wide, 0.29 × total length of scape, rest of scape longitudinally striate, 3.5 × as long as wide; pedicel longer than F 1; F 1 the shortest funicle segment, F 2 a little shorter than F 3, F 4 as long as F 5 (the longest funicle segments), F 6 –F 8 each a little shorter than preceding segment, F 4 –F 8 each with 2 mps; clava with 8 mps, 2.4 × as long as wide, about as long as combined length of F 6 –F 8.

Mesosoma ( Fig. 10 View FIGURES 8 – 11 ). Mesoscutum and scutellum finely longitudinally striate. In the holotype, propodeum ( Fig. 9 View FIGURES 8 – 11 ) with submedian lines distinct and complete, wider at propodeal posterior margin than at anterior margin and not connecting to each other, as typical for G. ( Gonatocerus   ), in the paratype apparently joining at anterior margin of propodeum but not extending to posterior margin of dorsellum (possibly an artifact due to poor mounting). Fore wing ( Fig. 11 View FIGURES 8 – 11 ) 3.8–4.1 × as long as wide; longest marginal seta about 0.28 × maximum wing width. Fore wing disc notably infumate throughout, mostly bare behind submarginal vein (except for a few setae behind its apex) and setose elsewhere. Hind wing 19 × 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 2.6 × maximum wing width.

Metasoma ( Fig. 10 View FIGURES 8 – 11 ). Gaster longer than mesosoma. Petiole short. Ovipositor occupying almost 0.9 × length of gaster, exserted beyond its apex by about 0.1 × own length; ovipositor length: mesotibia length ratio 1.3– 1.4: 1.

Measurements (µm) of the holotype. Mesosoma 450; petiole 27; gaster 584; ovipositor 510. Antenna: radicle 72; rest of scape 173; pedicel 76; F 1 39; F 2 46; F 3 52; F 4 72; F 5 72; F 6 67; F 7 64; F 8 58; clava 200. Fore wing 1070: 264; longest marginal seta 75. Hind wing 867: 45; longest marginal seta 118.

MALE. Unknown.

Diagnosis. Gonatocerus bukashka   is characterized by the antenna ( Fig. 8 View FIGURES 8 – 11 ) with 2 mps on F 4 –F 8 and relatively short F 1 –F 3.

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

Hosts. Unknown.
