 Type material. Holotype female [ZIN] on slide: RUSSIA. PRIMORSKIY KRAY, Ussuriyskiy rayon, Gornotayozhnoye, 12–17.viii.1999, M.V. Michailovskaya, MT. Paratypes, same locality and collector: 24.vii– 1.viii.1999 [1 Ƥ on slide, UCRC]; 5–11.viii.1999 [1 Ƥ on slide, UCRC]; 12–17.viii.1999 [2 Ƥ on slides, IBPV, UCRC]; 10–15.ix.1999 [1 Ƥ on slide, CNCI]; 1–10.viii.2000 [1 Ƥ on slide, UCRC]; ix–xi.2001 [1 Ƥ on point, UCRC]; 1–11.ix.2002 [1 Ƥ on slide, ZIN]; 24.ix–5.x.2002 [1 Ƥ on slide, UCRC].   
 Description. FEMALE. Body length 1120–1240 µm. Body mostly brown except base of gaster light brown and mesosoma with lighter patches on edges of midlobe of mesoscutum and scutellum; scape and pedicel light brown to brown, flagellum brown to dark brown; legs light brown to brown.   
Antenna (Fig. 195) with radicle 0.34–0.36× total length of scape, rest of scape 3.3–3.8× as long as wide, faintly longitudinally striate; pedicel longer than F1; F1–F3 a little shorter than F4 and F1–F4 shorter than following funicle segments, F5 the longest and F8 the broadest among funicle segments, F8 with a large incision at apex; mps on F5 (usually 2, rarely 1), F6 (2), F7 (2), and F8 (4); clava with 9 mps, 3.3–3.8× as long as wide, about as long as combined length of F6–F8.  
Mesosoma (Fig. 196). Propodeum (Fig. 197) with submedian lines wide apart. Fore wing (Fig. 198) 2.9–3.3× as long as wide; longest marginal seta 0.26–0.32× maximum wing width; disc with a faint but conspicuous brownish tinge, bare behind submarginal vein and densely setose elsewhere. Hind wing narrow, 19–25× as long as wide; disc sparsely setose and almost hyaline; longest marginal seta 2.6–3.4× maximum wing width.  
Metasoma (Fig. 196) longer than mesosoma. Petiole 1.7–1.9× as wide as long. Ovipositor occupying 0.7– 0.8× length of gaster, not or just barely exserted beyond its apex; ovipositor length: mesotibia length ratio normally 1.2–1.4:1.  
Measurements (µm) of the holotype. Mesosoma 443; petiole 24; gaster 566; ovipositor 431. Antenna: radicle 109; rest of scape 191; pedicel 61; F1 39; F2 45; F3 46; F4 52; F5 66; F6 62; F7 62; F8 63; clava 203. Fore wing 1088:338; longest marginal seta 100. Hind wing 886:36; longest marginal seta 112.  
MALE. Unknown.  
 Diagnosis. Gonatocerus ucri is most similar to G. krasavchik from which it differs by a notably darker body color and also in lacking mps on F4 of the female antenna (F4 with at least 1 mps on the female antenna of G. krasavchik). Also, G. ucri differs from the somewhat similar Indian species G. (Lymaenon) berijamus Mani & Saraswat in bearing 2 mps on F7 of the female antenna whereas in G. berijamus F7 of the female antenna bears 4 mps (Zeya & Hayat 1995).   
 Etymology. The species is named after the University of California at Riverside, which is commonly abbreviated as UCR.   
 Hosts. Unknown.
