( Figs 59–61 View FIGURES 59 – 61 )

Gonatocerus urocerus Ogloblin 1935: 72   –74 + plates (láminas) VI and VII (illustrations). Type locality: La Plata, Buenos Aires, Argentina.

Gonatocerus (Gonatocerus) urocerus Ogloblin   : De Santis 1967: 105 (catalog).

Gonatocerus urocerus Ogloblin   : De Santis 1989: 72 (catalog, record from Uruguay); Yoshimoto 1990: 41 (list); Loiácono et al. 2005: 17 (type information, incorrectly listed as being lost); Luft Albarracin et al. 2009: 10 (list; distribution in Argentina).

Type material examined. Lectotype female [MLPA], here designated to avoid confusion about the status of the type specimens of this species, on slide labeled: 1. “ Gonatocerus urocerus   A. O. ♀ La Plata vi.1931. J. A. Rosas Costa Typus.”; 2. “3867”. The lectotype, although uncleared, is in good condition, complete, perfectly spread out and mounted dorsoventrally. Paralectotypes [both MLPA]: 1 ♀ on slide labeled: “ Gonatocerus urocerus   A. O. ♀ La Plata. vi.1931. J. A. Rosas Costa. Paratypus [ip]”; 1 ♀ on slide labeled: “ Gonatocerus urocerus   A. O ♀ [ mexicanus   ♀ Perk. – ip] La Plata vi.1931. J. A Rosas Costa”.

Redescription. FEMALE (lectotype, paralectotypes, and non-type specimens). Body length 693–924 µm. Body mostly dark brown except base and apex of gaster, and also parts of mesosoma light brown; scape and pedicel light brown to brown, except radicle yellowish to light brown, flagellum dark brown; legs mostly light brown except tarsi usually a little darker, (brown).

Antenna ( Fig. 59 View FIGURES 59 – 61 ) with radicle 3.8–4.0x as long as wide, 0.33–0.4x total length of scape, rest of scape about 3.4x as long as wide, smooth; F1 a little shorter than pedicel or F2; F2–F6 more or less subequal in length, a little shorter than F7 or F8, mps on F4 (0 or 1), F5 (2), F6 (0 or 1), F7 (2), F8 (2); clava with 8 mps, 3.1–3.5x as long as wide, about as long as combined length of F6–F8.

Mesosoma ( Fig. 60 View FIGURES 59 – 61 ). Pronotum 2-lobed (mediolongitudinally divided), not entire as drawn by Ogloblin (1935). Mesoscutum and posterior scutellum with weak sculpture. Dorsellum rhomboidal. Forewing ( Fig. 61 View FIGURES 59 – 61 ) 4.4–4.6x as long as wide; longest marginal seta about 0.5x maximum wing width. Forewing disc slightly infumate, bare behind submarginal vein, and setose behind and beyond marginal vein. Hind wing 29–32x as long as wide; disc mostly bare except for rows of setae along margins and several scattered setae, slightly infumate at apex; longest marginal seta 4.4–4.7x maximum wing width.

Metasoma ( Fig. 60 View FIGURES 59 – 61 ) longer than mesosoma. Petiole very short, much wider than long. Ovipositor with a small basal loop, almost entire length of gaster, exserted beyond its apex by about 0.3x own length; ovipositor length: mesotibia length ratio 1.9–2.1:1.

Measurements (µm) of the lectotype. Body: total body length: 769; mesosoma 297; petiole 9; gaster 379; ovipositor 536. Antenna: radicle 70; rest of scape 91; pedicel 55; F1 39; F2 46; F3 46; F4 43; F5 48; F6 47; F7 52; F8 52; clava 158. Forewing 898:197; longest marginal seta 103. Hind wing 688:24; longest marginal seta 112.

MALE. Unknown.

Diagnosis. Gonatocerus (Gonatocerus) urocerus   is characterized by the female antenna ( Fig. 59 View FIGURES 59 – 61 ) with mps usually on F4, F5, F7, and F8, and also sometimes one mps on F6, a narrow forewing (4.4–4.6x as long as wide) with a slightly and uniformly infumate disc ( Fig. 61 View FIGURES 59 – 61 ), and an ovipositor exserted beyond the apex of the gaster by about 0.3x own length ( Fig. 60 View FIGURES 59 – 61 ). It could be confused with G. (Gonatocerus) mexicanus   , whose female antenna ( Fig. 43 View FIGURES 43 – 46 ) has two mps on F6, and whose ovipositor has usually a relatively larger basal loop ( Fig. 45 View FIGURES 43 – 46 ).

Distribution. NEOTROPICAL: Argentina, and Uruguay.

Hosts. Unknown.
