Gonatocerus (Lymaenon) komarik Triapitsyn , sp. n.

( Figs 116–119 )

Type material. Holotype female [ UCRC] on slide: FRANCE. GIRONDE , Sainte Colombe , 44°54’N 00°02’W, 13.viii.1998, M. van Helden, MT [ UCRC ENT 294201 ]. Paratype: same location and collector as holotype, 14.ix.2000 [1 Ƥ on slide, UCRC].

Description. FEMALE. Head ( Fig. 116 ) and mesosoma mostly dark brown, gaster mostly brown except light brown basally; scape and pedicel brown, flagellum dark brown, legs mostly brown or dark brown with some light brown.

Antenna ( Fig. 117 ) with radicle 0.29× total length of scape, rest of scape 3.1× as long as wide, faintly sculptured; pedicel longer than F1; F1 and F2 shorter than following funicle segments, F3 about as long as F5 and both the longest funicle segments although only slightly longer than F4, F6, or F7; mps on F6 (0 or 1), F7 (2) and F8 (2); clava with 8 mps, 3.3× as long as wide, a little shorter than combined length of F6–F8.

Mesosoma ( Fig. 118 ). Propodeum with submedian lines moderately close to each other. Fore wing ( Fig. 119 ) 3.1–3.3× as long as wide; longest marginal seta 0.21–0.24× maximum wing width; disc with a slight brownish tinge, mostly bare behind submarginal vein except behind its apex and setose elsewhere. Hind wing ( Fig. 119 ) 20× as long as wide; disc densely setose and with a slight brownish tinge; longest marginal seta 2.5× maximum wing width.

Metasoma ( Fig. 118 ). Gaster notably longer than mesosoma. Petiole 1.9× as wide as long. Ovipositor projecting forward under petiole and extending to posterior margin of propodeum anteriorly and slightly exserted beyond gastral apex posteriorly (by 0.08× own length); ovipositor length: mesotibia length ratio 2.1:1.

Measurements (µm) of the holotype. Mesosoma 375; petiole 27; gaster 560; ovipositor 640. Antenna: radicle 58; rest of scape 140; pedicel 55; F1 27; F2 39; F3 61; F4 58; F5 61; F6 60; F7 58; F8 51; clava 155. Fore wing 1014:333; longest marginal seta 70. Hind wing 775:39; longest marginal seta 97.

MALE. Unknown.

Diagnosis. Gonatocerus komarik is characterized by the ovipositor projecting forward under the petiole to the posterior margin of propodeum ( Fig. 118 ); it differs from G. kusaka , which sometimes also has this feature, in lacking mps on F5 and in having only 2 mps on F8, and also by the ovipositor relatively less exserted beyond the gastral apex. Among the European species of the subgenus, G. komarik is somewhat similar to G. longior Soyka from which it differs, besides the ovipositor projecting forward under the petiole, by bearing 8, rather than 10 (as in G. longior ) mps on the clava. See also the diagnosis of G. kulik .

Etymology. The species name (a noun in apposition) stands for a little mosquito in Russian.

Hosts. Unknown.
