Type material examined. Gonatocerus longior Soyka: holotype female [NHMW] on slide (Fig. 158) labeled: 1. “ Gonatocerus longior Ƥ (Soyka) det. W. Soyka”; 2. [red] “Type”; 3. [Soyka’s slide number] “796”; 4. “ 14. Sept. 1930 Valkenburg [two words crossed out in ink] [two illegible words] Canadabalsam”. The holotype is complete, uncleared, and mounted laterally.

Gonatocerus conicus (Mathot): holotype female of Lymaenon conicus Mathot [ISNB] on slide (Fig. 159) labeled: 1. “Université de Louvain LAB. ENTOMOLOGIE Tervueren [sic] 23.VIII.44 266”; 2. “Dr. H.

Distribution. PALAEARCTIC: Austria *, Belgium (Mathot 1969) [as Lymaenon conicus], Bulgaria (Donev 2001 [record needs conformation because Donev (2005) did not list this species from Bulgaria]), Denmark *, France *, Georgia *, Germany [may be a new record because the previous listing of this species from Germany by Donev (2001) needs confirmation], Greece (Donev 2005), Hungary *, Italy *, Kyrgyzstan *, Netherlands, Russia *, Spain (Baquero & Jordana 2003), Switzerland *, Turkey (Donev 2001, 2005), UK: England (Matthews 1986), and Wales *. ORIENTAL: India (Zeya & Hayat 1995). The previous record of this species from Austria by Soyka (1946), cited by Baquero & Jordana (2003), was erroneous.

Redescription. FEMALE (holotypes of G. longior and Lymaenon conicus, and non-type specimens). Body length 825–1025 µm. Body (Fig. 160) mostly brown except gaster light brown basally, appendages light brown to brown.

Antenna (Figs 160, 161, 164) with radicle 0.31–0.35× total length of scape, rest of scape 3.4–3.5× as long as wide; pedicel longer than F1; F1 about as long as F2, a little shorter than F3 and F4; F5 the longest funicle segment, F6–F8 slightly shorter and F8 with an incision at apex; mps on F5 (usually 1, rarely 0 or 2), F6 (0 or 1), F7 (1 or 2), and F8 (2); clava with 10 mps, 3.1–3.8× as long as wide, a little shorter than combined length of F6–F8. Mesosoma (Figs 160, 165). Propodeum (Fig. 166) with submedian lines wide apart. Fore wing (Figs 160, 163, 167) 2.9–3.4× as long as wide; longest marginal seta 0.25–0.3× maximum wing width. Fore wing disc hyaline, bare behind submarginal vein, more or less sparsely setose between marginal vein and cubital row of setae (often leaving a bare area but occasionally such area not evident) and densely setose elsewhere. Hind wing (Fig. 168) 22–23× as long as wide; disc hyaline, unevenly setose; longest marginal seta 2.8–3.3× maximum wing width.

Metasoma (Figs 160, 162, 165) longer than mesosoma. Petiole about 2.5× as wide as long. Ovipositor occupying from about 0.8× to entire length of gaster, usually exserted beyond its apex by 0.06–0.09× own length; ovipositor usually 1.9–2.1× length of mesotibia but occasionally as low as 1.7×.

Measurements (µm) of the holotype of G. longior . Head: 132; mesosoma 338; gaster 529; ovipositor 550. Antenna: radicle 48; rest of scape 106; pedicel 57; F1 30; F2 30; F3 37; F4 40; F5 64; F6 52; F7 58; F8 60; clava 157. Fore wing 953:332; longest marginal seta 84. Hind wing 800:36; longest marginal seta 100.

Description. MALE. Body length (measurement taken from dry-mounted specimen from Fryazevo, Moskovskaya oblast’, Russia before slide-mounting) 896 µm. Head and mesosoma mostly brown except pronotum yellow to light brown; scape and pedicel yellow to light brown, flagellum brown; legs yellow to light brown; basal gastral terga yellowish, apical ones brown. Antenna (Fig. 169) with scape 2.1–2.4× as long as wide. Fore wing (Fig. 170) about 3.2× as long as wide; hind wing (Fig. 170) about 24× as long as wide. Genitalia as in Fig. 171.

Diagnosis. Gonatocerus longior is recognizable by the fore wing (Figs 163, 167, 170) with sparse setae between the marginal vein and the cubital row of setae (often leaving a distinct bare area), the female antenna (Figs 161, 164) usually bearing 1 mps on F5, 0 or 1 mps on F6, 1 or 2 mps on F7, 2 mps on F8, and 10 mps on the clava, and also by the relatively long ovipositor (Figs 162, 165) which is usually 1.9–2.1× as long as mesotibia.

Hosts. Unknown.
