Gonatocerus (Lymaenon) saulfrommeri Triapitsyn , sp. n.

( Figs 176–179 )

Type material. Holotype female [ ZIN] on slide: RUSSIA. PRIMORSKIY KRAY, Ussuriyskiy rayon , Gornotayozhnoye , 1–10.vi.2002, M.V. Michailovskaya, MT .

Description. FEMALE. Head and mesosoma dark brown, gaster mostly brown to dark brown except a little lighter basally; antenna brown except scape partially light brown, legs light brown with some light and dark brown.

Antenna ( Fig. 176 ) with radicle 0.27× total length of scape, rest of scape 3.6× as long as wide; pedicel longer than F1; F1 the shortest and F5 the longest among funicle segments (all notably longer than wide), F8 the broadest funicle segment; mps on F4 (0 or 1), F5 (2), F6 (1), F7 (3) and F8 (4); clava with 12 or 13 mps, 3.6× as long as wide, almost as long as combined length of F6–F8.

Mesosoma ( Fig. 178 ). Propodeum ( Fig. 177 ) with submedian lines moderately close to each other. Fore wing ( Fig. 179 ) 3.0× as long as wide; longest marginal seta 0.21× maximum wing width; disc with a brownish tinge, mostly bare behind submarginal vein except with setae behind its apex and densely setose elsewhere. Hind wing about 21× as long as wide; disc densely setose and with a slight brownish tinge; longest marginal seta about 2.5× maximum wing width.

Metasoma ( Fig. 178 ). Gaster a little longer than mesosoma. Petiole 2.2× as wide as long. Ovipositor occupying 0.6× length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 0.9:1.

Measurements (µm). Mesosoma 541; petiole 29; gaster 560; ovipositor 348. Antenna: radicle 70; rest of scape 185; pedicel 73; F1 45; F2 58; F3 58; F4 74; F5 87; F6 76; F7 76; F8 75; clava 224. Fore wing 1322:443; longest marginal seta 94. Hind wing 996:48; longest marginal seta 118.

MALE. Unknown.

Diagnosis. Gonatocerus saulfrommeri differs from the only two other Palaearctic species of G. ( Lymaenon ) which have 12 or more mps on the clava, G. katraps and G. krasavchik , by a shorter ovipositor which is 0.9× length of mesotibia (ovipositor at least 1.1× length of mesotibia in G. krasavchik , whose head and mesosoma are also much lighter, and at least 1.5× length of mesotibia in G. katraps ).

Etymology. The species is named in honor of my good friend and colleague Saul I. Frommer, Curator Emeritus of the UCRC.

Hosts. Unknown.
