Gonatocerus (Lymaenon) kulik Triapitsyn , sp. n.

( Figs 125–128 )

Type material. Holotype female [ ZIN] on slide: RUSSIA. PRIMORSKIY KRAY, Ussuriyskiy rayon, Gornotayozhnoye , viii–ix.1999, M.V. Michailovskaya, YPT. Paratypes, same locality and collector: viii–ix.1999 [1 Ƥ on slide, UCRC]; 10–15.ix.1999 [1 Ƥ on slide, CNCI]; 18–19.vi.2000 [1 Ƥ on slide, IBPV]; 17.viii.2001 [1 Ƥ on slide, UCRC]; 1–10.vi.2002 [1 Ƥ on slide, UCRC].

Description. FEMALE. Body mostly dark brown; scape and pedicel brown, flagellum dark brown; legs mostly brown.

Antenna ( Fig. 125 ) with radicle 0.31–0.35× total length of scape, rest of scape 2.8–3.7× as long as wide, faintly longitudinally striate; pedicel longer than F1; F1–F3 a little shorter than F4 and F1–F4 shorter than following funicle segments, F5 the longest among funicle segments; mps on F5 (2), F6 (1 or 2), F7 (2), and F8 (2 or 3); clava usually with 9 mps but with 11 mps in one paratype, 2.5–3.0× as long as wide, a little shorter than combined length of F6–F8.

Mesosoma ( Fig. 126 ). Propodeum with submedian lines very wide apart posteriorly. Fore wing ( Fig. 127 ) about 2.9× as long as wide; longest marginal seta 0.27–0.3× maximum wing width; disc with a faint brownish tinge, bare behind submarginal vein except for 1 or 2 setae behind its apex, with setae sparse between marginal vein and cubital row of setae sometimes leaving a small bare area, and densely setose elsewhere. Hind wing ( Fig. 128 ) 16–19× as long as wide; disc unevenly but rather densely setose and with a brownish tinge apically; longest marginal seta 2.3–2.6× maximum wing width.

Metasoma ( Fig. 126 ). Gaster longer than mesosoma. Petiole 1.9–2.0× as wide as long. Ovipositor occupying entire length of gaster, often projecting forward under petiole and extending to posterior margin of propodeum anteriorly, and exserted beyond its apex posteriorly by 0.05–0.11× own length; ovipositor length: mesotibia length ratio normally 2.2–2.4:1 but in two paratypes 2.6:1 and 3.0:1 respectively.

Measurements (µm) of the holotype. Mesosoma 320; petiole 29; gaster 535; ovipositor 591. Antenna: radicle 55; rest of scape 124; pedicel 50; F1 25; F2 29; F3 34; F4 42; F5 59; F6 55; F7 55; F8 52; clava 148. Fore wing 907:314; longest marginal seta 94. Hind wing 726:42; longest marginal seta 109.

MALE. Unknown.

Diagnosis. Gonatocerus kulik differs from the following Palaearctic species of G. ( Lymaenon ) whose females have somewhat similar long ovipositors and general appearance: from G. komarik in bearing 2 mps on F5 (F5 without mps in the latter species); from G. acuminatus in having the ovipositor exserted by at most 0.11× own length (usually significantly less) and in usually lacking a distinct or large bare area on the fore wing disc between the marginal vein and the cubital row of setae (the ovipositor is exserted by about 0.2× own length and the fore wing has a large, distinct such bare area in the latter species); from G. berezovskiyi in having F3 much shorter than F5 and the clava with at least 9 mps (F3 is about as long as F5 and the clava with 8 mps in the latter species); and from G. kusaka in having the ovipositor exserted by at most 0.11× own length, in bearing 2 or 3 mps on F8, and in having usually setae sparse on the fore wing disc between the marginal vein and the cubital row of setae sometimes leaving a small bare area (the ovipositor is exserted by at least 0.17× own length, F8 with 4 or 5 mps, and the fore wing disc is densely and more or less uniformly setose between the marginal vein and the cubital row of setae in the latter species).

Etymology. “ Kulik ” (a noun in apposition) is a common name in Russian for a sandpiper, curlew, or a snipe bird.

Hosts. Unknown.
