NEARCTIC: Canada, Mexico, and USA (Huber 1988; Triapitsyn et al. 2010). Redescription. See Huber (1988) (based on specimens from North America). Diagnosis. FEMALE (based on specimens from Europe). Body mostly dark brown, appendages light to dark brown; antenna (Figs 264, 268) with scape minus radicle 2.8–3.3× as long as wide, F1 and F2 the shortest funicle segments, F3 a little longer than F2 or F4, mps on F3 (usually 2, occasionally 1 on one antenna), F4 (0 or 1), F5 (2), F6 (1 or 2), F7 (2), F8 (2), clava with 8 mps; propodeum (Figs 265, 269) with submedian carinae complete, curving anteriorly and posteriorly; fore wing (Figs 267, 270) 2.6–2.9× as long as wide, with disc almost hyaline, mostly bare behind venation except for a few setae behind stigmal vein; hind wing (Fig. 270) 12–14× as long as wide; ovipositor occupying 0.7–0.8× length of gaster (Fig. 266), 1.0–1.1× as long as mesotibia, not exserted beyond gastral apex. MALE. Not known from Europe. The hind wing width and chaetotaxy seems to be quite variable among the examined specimens to G. latipennis both from North America and Europe, being 11–13× as long as wide and rather densely setose in some North American specimens (Fig. 282); Huber (1988) also noticed that the hind wing width is fairly variable in this species. Also illustrated here are the antenna (Fig. 278), mesosoma (Fig. 279), and fore wing (Fig. 280) of the female from New York, USA, as well as the propodeum (Fig. 281) and fore wing (Fig. 282) of the female from California, USA. Hosts. Unknown (Huber 1988). The host record of the blue-green sharpshooter, Graphocephala atropunctata (Signoret) (Cicadellidae), in California by Boyd et al. (2004) and Boyd & Hoddle (2006) was due to my initial misidentification as G. latipennis. After a more thorough examination of additional specimens of G. latipennis from the USA, I found that the reported parasitoid of G. atropunctata belongs to a new species of G. (Cosmocomoidea) which will be described elsewhere. Comments. Note that the illustration of the propodeum of G. latipennis in Huber (1988, p. 99) is mislabeled: his fig. 72 is of G. latipennis whereas fig. 73 is of G. (Cosmocomoidea) morrilli (Howard). The following records of G.? latipennis from the eastern Palaearctic region and also of a female from Stavropol’skiy kray, Russia, need confirmation because they have the fore wing disc seemingly relatively more setose behind the stigmal vein (Figs 273, 277) than in specimens from England (Fig. 267) and Krasnodarskiy kray, Russia (Fig. 270), or from USA (Figs 280, 282) while other features such as female antenna (Fig. 271) and propodeum (Fig. 272) are the same as in G. latipennis. In some specimens from the Russian Far East the ovipositor is 1.3× as long as mesotibia and slightly exserted beyond the gastral apex. The male of this form, which may represent a separate species, is similar to female, including the shape of the submedian carinae on the propodeum (Fig. 275), and except for the normal sexually dimorphic features: antenna (Fig. 274) with F1 wider than other flagellomeres, and genitalia (Fig. 276).
