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 View FIGURES 195 – 198 ) 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 F 1; F 1 –F 3 a little shorter than F 4 and F 1 –F 4 shorter than following funicle segments, F 5 the longest and F 8 the broadest among funicle segments, F 8 with a large incision at apex; mps on F 5 (usually 2, rarely 1), F 6 (2), F 7 (2), and F 8 (4); clava with 9 mps, 3.3–3.8 × as long as wide, about as long as combined length of F 6 –F 8.

Mesosoma ( Fig. 196 View FIGURES 195 – 198 ). Propodeum ( Fig. 197 View FIGURES 195 – 198 ) with submedian lines wide apart. Fore wing ( Fig. 198 View FIGURES 195 – 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 View FIGURES 195 – 198 ) 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; F 1 39; F 2 45; F 3 46; F 4 52; F 5 66; F 6 62; F 7 62; F 8 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 F 4 of the female antenna (F 4 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 F 7 of the female antenna whereas in G. berijamus   F 7 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.
