Gonatocerus (Cosmocomoidea) rogersi Matthews, 1986

(Figs 304–308)

Gonatocerus rogersi Matthews 1986: 22 (member of the ater species group).

Type locality: Awbridge, Hampshire Co., England, UK.

Gonatocerus rogersi Matthews: Pricop 2010b: 113 (mentioned as valid species).

Type material examined. Holotype female [BMNH] on slide (Fig. 304) labeled: 1. “Holotype Ƥ Gonatocerus rogersi sp. n. det. Matthews 1984 Holotype [in red circle]”; 2. “ ENGLAND: HANTS Awbridge v.1981 C. Vardy 29 NOV 1983 M1034/”. The holotype is in good condition, nicely dissected under 5 coverslips.

Distribution. PALAEARCTIC: UK (England).

Redescription. FEMALE. Body color is difficult to assess because the specimen had been well cleared before being slide-mounted (Matthews 1986), most likely head and mesosoma brown or dark brown and gaster brown.

Antenna (Fig. 305) with radicle 0.25× total length of scape, rest of scape 3.5× as long as wide; pedicel longer than F1; F1 the shortest funicle segment, F3 a little longer than F2 and about as long as F4, F5 the longest funicle segment, F6 and F7 subequal and slightly longer than F8; mps on F4 (0 or 1), F5 (2), F6 (1), F7 (1 or 2), and F8 (2); clava with 8 mps, about 3.8× as long as wide, slightly longer than combined length of F6–F8.

Mesosoma (Fig. 306) shorter than metasoma. Propodeum with fine, parallel submedian carinae extending almost to anterior margin of propodeum and slightly curving towards each other there but not connecting. Fore wing (Fig. 307) about 4.1× as long as wide; longest marginal seta 0.34–0.35× maximum wing width; disc notably infumate, bare behind submarginal and marginal veins except for 3 setae behind marginal vein and densely setose elsewhere. Hind wing (Fig. 307) about 25× as long as wide; disc slightly infumate; longest marginal seta 3.1× maximum wing width.

Metasoma (Fig. 308). Ovipositor occupying about 0.6× length of gaster, not exserted beyond its apex, about 1.0× as long as mesotibia.

Measurements (µm). Mesosoma 351; petiole: 21; gaster 503; ovipositor 303. Antenna: radicle 39; rest of scape 116; pedicel 55; F1 30; F2 45; F3 52; F4 52 (55); F5 61; F6 55; F7 55; F8 51; clava 176. Fore wing 922:226; longest marginal seta 78. Hind wing 713:29; longest marginal seta 90.

MALE. Unknown.

Diagnosis. Gonatocerus rogersi, known from the female holotype only, is characterized by a narrow fore wing (about 4.1× as long as wide) with a notably infuscate disc (Fig. 307).

Hosts. Unknown.
