( Figs 158–171 View FIGURE 158 View FIGURES 159, 160 View FIGURES 161 – 163 View FIGURES 164 – 168 View FIGURES 169 – 171 )

Gonatocerus longior Soyka 1946: 38   –39. Type locality: Valkenburg, Limburg, Netherlands [not Hundsheim, Lower Austria, Austria as erroneously indicated in the original description].

Lymaenon conicus Mathot 1969: 2   (list), 3 –5, 10 (key). Type locality: Tervuren, Flemish Brabant, Belgium. Syn. n. Gonatocerus longior Soyka   : Matthews 1986: 224 (diagnosis, distribution); Viggiani & Jesu 1986: 31 (compared with Lymaenon vidanoi   ); Zeya & Hayat 1995: 100 –101 (redescription, distribution) + 148 (illustrations); Baquero & Jordana 2003: 12 –13 (diagnosis, redescription, distribution); Donev 2005: 381 (diagnosis, distribution). Gonatocerus conicus (Mathot)   : Noyes (2012).

Type material examined. Gonatocerus longior Soyka   : holotype female [ NHMW] on slide ( Fig. 158 View FIGURE 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 View FIGURES 159, 160 ) labeled: 1. “Université de Louvain LAB. ENTOMOLOGIE Tervueren [sic] 23.VIII. 44 266 ”; 2. “Dr. H. DEBAUCHE det. Lymaenon conicus Deb. Ƥ   Type ”. The holotype ( Fig. 160 View FIGURES 159, 160 ) is in fair condition although it is uncleared, almost complete (lacking apex of one of the hind wings), and mounted laterally.

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 View FIGURES 159, 160 ) mostly brown except gaster light brown basally, appendages light brown to brown.

Antenna ( Figs 160 View FIGURES 159, 160 , 161 View FIGURES 161 – 163 , 164 View FIGURES 164 – 168 ) with radicle 0.31–0.35 × total length of scape, rest of scape 3.4–3.5 × as long as wide; pedicel longer than F 1; F 1 about as long as F 2, a little shorter than F 3 and F 4; F 5 the longest funicle segment, F 6 –F 8 slightly shorter and F 8 with an incision at apex; mps on F 5 (usually 1, rarely 0 or 2), F 6 (0 or 1), F 7 (1 or 2), and F 8 (2); clava with 10 mps, 3.1–3.8 × as long as wide, a little shorter than combined length of F 6 –F 8.

Mesosoma ( Figs 160 View FIGURES 159, 160 , 165 View FIGURES 164 – 168 ). Propodeum ( Fig. 166 View FIGURES 164 – 168 ) with submedian lines wide apart. Fore wing ( Figs 160 View FIGURES 159, 160 , 163 View FIGURES 161 – 163 , 167 View FIGURES 164 – 168 ) 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 View FIGURES 164 – 168 ) 22–23 × as long as wide; disc hyaline, unevenly setose; longest marginal seta 2.8–3.3 × maximum wing width.

Metasoma ( Figs 160 View FIGURES 159, 160 , 162 View FIGURES 161 – 163 , 165 View FIGURES 164 – 168 ) 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; F 1 30; F 2 30; F 3 37; F 4 40; F 5 64; F 6 52; F 7 58; F 8 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 View FIGURES 169 – 171 ) with scape 2.1–2.4 × as long as wide. Fore wing ( Fig. 170 View FIGURES 169 – 171 ) about 3.2 × as long as wide; hind wing ( Fig. 170 View FIGURES 169 – 171 ) about 24 × as long as wide. Genitalia as in Fig. 171 View FIGURES 169 – 171 .

Diagnosis. Gonatocerus longior   is recognizable by the fore wing ( Figs 163 View FIGURES 161 – 163 , 167 View FIGURES 164 – 168 , 170 View FIGURES 169 – 171 ) with sparse setae between the marginal vein and the cubital row of setae (often leaving a distinct bare area), the female antenna ( Figs 161 View FIGURES 161 – 163 , 164 View FIGURES 164 – 168 ) usually bearing 1 mps on F 5, 0 or 1 mps on F6, 1 or 2 mps on F7, 2 mps on F 8, and 10 mps on the clava, and also by the relatively long ovipositor ( Figs 162 View FIGURES 161 – 163 , 165 View FIGURES 164 – 168 ) which is usually 1.9–2.1 × as long as mesotibia. Hosts. Unknown.
