Gonatocerus (Cosmocomoidea) kikimora Triapitsyn , sp. n.

( Figs 257–260 )

Type material. Holotype female [ ZIN] on slide: RUSSIA. PRIMORSKIY KRAY, Ussuriyskiy rayon, Gornotayozhnoye , ix.1999, M.V. Michailovskaya, YPT. Paratype: same data as the holotype except collected 5– 11.viii.1999, MT [1 Ƥ on slide, UCRC].

Description. FEMALE. Head, mesosoma, and flagellum dark brown; scape, pedicel, and gaster brown; legs light to dark brown.

Antenna ( Fig. 257 ) with radicle about 0.2× total length of scape, rest of scape 2.8–3.3× as long as wide, slightly longitudinally striate; pedicel much longer than F1; F2 shorter than following funicle segments, F3–F7 more or less subequal in length and a little longer than F8; mps on F2 (1), F3–F8 (2 each) except F2 with 2 mps on one antenna in the paratype and F4 with only 1 mps on one antenna in the holotype; clava with 8 mps, long (4.1– 4.3× as long as wide), about as long as combined length of F5–F8.

Mesosoma ( Fig. 258 ). Propodeum ( Fig. 259 ) with well-developed submedian carinae extending to anterior margin of propodeum and not connecting to each other there. Fore wing ( Fig. 260 ) 2.6–2.7× as long as wide; longest marginal seta 0.17–0.18× maximum wing width; disc with a brownish tinge throughout, bare behind venation except for at least 8 setae behind stigmal vein. Hind wing ( Fig. 260 ) about 13× as long as wide; disc with a row of setae along each margin and additional setae basally and apically, almost hyaline; longest marginal seta about 1.6× maximum wing width.

Metasoma ( Fig. 258 ) longer than mesosoma. Petiole about 0.5× as long as wide. Ovipositor occupying 0.5–0.6× length of gaster, not or slightly exserted beyond its apex (by at most 0.1× own length); ovipositor length: mesotibia length ratio 1.0–1.1:1.

Measurements (µm) of the holotype. Mesosoma 530; petiole 30; gaster 744; ovipositor 424. Antenna: radicle 45; rest of scape 188; pedicel 64; F1 30; F2 49; F3 67; F4 62; F5 67; F6 62; F7 64; F8 55; clava 251. Fore wing 1242:467; longest marginal seta 82. Hind wing 978:75; longest marginal seta 118.

MALE. Unknown.

Diagnosis. Gonatocerus kikimora is similar to G. crassicornis and G. kodaianus (Mani & Saraswat) . It differs from G. crassicornis in having a much longer clava (at least 4.1× as long as wide), about as long as combined length of F5–F8; in G. crassicornis the clava is about 2.6× as long as wide and a little longer than combined length of F6–F8. Gonatocerus kikimora differs from G. kodaianus by the relatively shorter and wider funicle segments ( Fig. 257 ), particularly a shorter F2 relative to the length of F3, and a relatively wider fore wing (at least 2.6× as long as wide); in G. kodaianus F2–F7 are notably longer than wide and the fore wing is at least 3.0× as long as wide ( Zeya & Hayat 1995).

Etymology. The species name (a noun in apposition) is of a bog-living legendary creature in Slavic mythology.

Hosts. Unknown.
