Gonatocerus (Cosmocomoidea) woohoo Triapitsyn , sp. n.

( Figs 317–321 )

Type material. Holotype female [ CAS] on slide: RUSSIA. SAKHALINSKAYA OBLAST’ , Sakhalin Island , about 6 km E of Sokol, 47°15.08’N 142°48.10’E, 12.viii.2001, D.J. Bennett, T. Anderson (collector’s code SK-01- DJB-077). Paratypes: same data as holotype [1 Ƥ on point, CAS; 2 Ƥ on slides, CAS, UCRC].

Description. FEMALE. Body length 960 µm (dry-mounted paratype). Head ( Fig. 318 ), pronotum, mesoscutum, axillae, scutellum, and middle gastral terga dark brown, rest of body brown; scape, pedicel, and legs mostly light brown, flagellum brown.

Antenna ( Fig. 317 ) long, with radicle about 0.2× total length of scape, rest of scape 3.5–4.0× as long as wide, slightly longitudinally striate; pedicel longer than F1; F1 the shortest funicle segment, F2 a little shorter than following funicle segments; mps on F3 (0 or 1), F4 (usually 1, sometimes 0), F5 (1), F6 (1), F7 (2), and F8 (2); clava long, with 8 mps, 3.9–4.3× as long as wide, a little longer than combined length of F6–F8.

Mesosoma ( Fig. 319 ). Propodeum ( Fig. 320 ) with well-developed, slightly curving submedian carinae narrowing toward and extending to propodeal anterior margin. Fore wing ( Fig. 321 ) 3.2–3.5× as long as wide; longest marginal seta 0.27–0.29× maximum wing width; disc with a brownish tinge throughout, bare behind submarginal vein, mostly bare behind base of marginal vein (except for a few setae just below it) and densely setose elsewhere including behind stigmal vein. Hind wing ( Fig. 321 ) 15–16× as long as wide; disc mostly bare and with a slight, uniform brownish tinge throughout; longest marginal seta about 1.9× maximum wing width.

Metasoma ( Fig. 319 ) a little longer than mesosoma. Petiole 1.5–1.6× as long as wide. Ovipositor 0.7–0.8× length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 0.9–1.0:1.

Measurements (µm) of the holotype. Mesosoma 424; petiole 32; gaster 470; ovipositor 360. Antenna: radicle 42; rest of scape 158; pedicel 63; F1 43; F2 61; F3 70; F4 73; F5 73; F6 70; F7 74; F8 67; clava 239. Fore wing 1230:387; longest marginal seta 103. Hind wing 929:61; longest marginal seta 115.

MALE. Unknown.

Diagnosis. Among the Palaearctic species of the subgenus, G. woohoo is characterized by the unique chaetotaxy on the fore wing disc which is setose behind stigmal vein and apex of marginal vein ( Fig. 321 ).

Etymology. The species name, treated here as a noun in apposition, is an interjection in English used to express sudden joy (of finding a new species).

Hosts. Unknown.
