Type material. Holotype female [ZIN] on slide: RUSSIA. PRIMORSKIY KRAY, Ussuriyskiy rayon, Gornotayozhnoye, 21–26.viii. 2000, M.V. Michailovskaya, MT. Paratypes, same locality and collector: 24.vii– 1.viii. 1999 [1 Ƥ on slide, UCRC]; 5–11.viii. 1999 [3 Ƥ on points, CNCI, IBPV, UCRC]; 12–17.viii. 1999 [1 Ƥ on slide, UCRC]; viii. 1999 [1 Ƥ on point, UCRC]; 28.viii– 5.ix. 1999 [1 Ƥ on point, UCRC]; 6–14.ix. 1999 [1 Ƥ on point, UCRC].

Description. FEMALE. Body length 1200–1400 µm (dry-mounted paratypes). Head mostly yellowish except vertex variably brownish and brown around ocelli, trabeculae dark brown; scape mostly light brown with some brown, pedicel brown, flagellum dark brown; mesosoma usually mostly orange-light brown with some brown on scutellum and sometimes also on midlobe of mesoscutum; gaster mostly yellow with a light brown band on middle terga; legs mostly light brown.

Antenna (Fig. 120) with radicle 0.36–0.4 × total length of scape, rest of scape 3.3–3.7 × as long as wide, with faint sculpture; pedicel usually a little longer than F 1; F 1 –F 3 a little shorter than following funicle segments, F 5 the longest and F 8 the broadest among funicle segments, F 8 with an incision at apex; mps on F 4 (usually 1, occasionally 2), F 5 (2), F 6 (2 to 4), F 7 (3), and F 8 (5); clava with at least 12 mps (possibly sometimes with as many as 15 mps), 3.0– 3.7 × as long as wide, slightly longer than combined length of F 6 –F 8.

Mesosoma (Fig. 121). Propodeum (Fig. 122) with submedian lines wide apart. Fore wing (Fig. 123) 2.9– 3.2 × as long as wide; longest marginal seta 0.2–0.25 × maximum wing width; disc with a faint brownish tinge (almost hyaline), bare behind submarginal vein and densely setose elsewhere. Hind wing (Fig. 124) 20–23 × as long as wide; disc sparsely setose and almost hyaline; longest marginal seta 2.5–2.8 × maximum wing width.

Metasoma (Fig. 121). Gaster longer than mesosoma. Petiole 1.2–1.5 × as wide as long. Ovipositor occupying 0.6–0.7 × length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio normally 1.1–1.2: 1 except 1.6: 1 in one paratype with a slightly darker-colored mesosoma.

Measurements (µm) of the holotype. Mesosoma 646; petiole 40; gaster 775; ovipositor 500. Antenna: radicle 136; rest of scape 202; pedicel 70; F 1 58; F 2 67; F 3 72; F 4 81; F 5 91; F 6 85; F 7 82; F 8 79; clava 282. Fore wing 1433: 449; longest marginal seta 109. Hind wing 1113: 48; longest marginal seta 136.

MALE. Unknown.

Diagnosis. Gonatocerus krasavchik is most similar to G. ucri from which it differs by a notably lighter body color (Fig. 121) and also in bearing at least 1 mps on F 4 (F 4 without mps in G. ucri). Also, G. krasavchik differs from the Oriental species G. narayani in having F 2 and F 3 of the female antenna notably longer than wide (Fig. 120) and in bearing at least 1 mps on F 4 whereas in G. narayani F 2 and F 3 of the female antenna are quadrate to broader than long and F 4 lacks mps (Zeya & Hayat 1995).

Etymology. The species name (a noun in apposition) means “a handsome” in Russian.

Hosts. Unknown.
