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 F 1; F 1 –F 3 a little shorter than F 4 and F 1 –F 4 shorter than following funicle segments, F 5 the longest among funicle segments; mps on F 5 ( 2), F 6 ( 1 or 2), F 7 ( 2), and F 8 ( 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 F 6 –F 8.

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; F 1 25; F 2 29; F 3 34; F 4 42; F 5 59; F 6 55; F 7 55; F 8 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 F 5 (F 5 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 F 3 much shorter than F 5 and the clava with at least 9 mps (F 3 is about as long as F 5 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 F 8, 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, F 8 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.
