description: Gonatocerus (Gonatocerus) bukashka Triapitsyn, sp. n.   
(Figs 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, F1 brown, remainder of flagellum dark brown; gaster and legs light brown to brown.   
Antenna (Fig. 8) 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 F1; F1 the shortest funicle segment, F2 a little shorter than F3, F4 as long as F5 (the longest funicle segments), F6–F8 each a little shorter than preceding segment, F4–F8 each with 2 mps; clava with 8 mps, 2.4× as long as wide, about as long as combined length of F6–F8.  
 Mesosoma (Fig. 10). Mesoscutum and scutellum finely longitudinally striate. In the holotype, propodeum (Fig. 9) 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) 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). 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; F1 39; F2 46; F3 52; F4 72; F5 72; F6 67; F7 64; F8 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) with 2 mps on F4–F8 and relatively short F1–F3.   
 Etymology. The species name is a noun in apposition meaning “a bug ” in Russian.   
 Hosts. Unknown.
