Gonatocerus (Gonatocerus) bukashka Triapitsyn , sp. n.

( 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. GoogleMaps 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 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 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 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; 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 View FIGURES 8 – 11 ) 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.
