O. ♀ Loreto, Misiones  5.x.1933. Fig.[ip, iR] A. A. O! Typus.”; 2. [iR] “[Coloration when alive dark red] (ruber). [Lipochromous red pigment]”. The lectotype, although uncleared, is in good condition, complete, perfectly spread out and mounted dorsoventrally.  Paralectotype ♂[ MLPA] on slide labeled: 1. “  Gonatocerus stenopterus A. O. ♂ Loreto, Misiones  20.xi.1933. A. A. O. Typ.fig. [ip, iR]”; 2. “3866”. The collection date of the male paralectotype( 20.xi.1933) does not match the published date ( 2.xi.1933), although without any doubt Ogloblin referred to this specimen. The second paralectotypefemale is missing from MLPA; according to the original description it had the same label data (collected 5.x.1933) as the lectotype. The two specimens of  G.( Gonatocerus) stenopterusin MLPA(both from Loreto, Misiones, Argentina; female collected 15.v.1934and male collected 7.iii.1935) ( Loiácono et al.2005) have no typestatus although it is possible that the female was part of the typeseries of this species provided Ogloblin (1936)incorrectly indicated its collection date.    Materialexamined. ARGENTINA.  BUENOS AIRES, Vieytes, 35°18’26.56’’S 57°34’02.99’’W,  16 m,  29.ii.2008, D.  A.

[Live specimens were stated to be darkish red ( Ogloblin 1936), but the body of the non-type specimen from Vieytes is brown to dark brown; the body length of this dry specimen is 860 µm].   FIGURES 54–56.  Gonatocerus( Gonatocerus) stenopterus♀ (lectotype): 54, antenna; 55, body; 56, wings. Antenna ( Fig. 54) with radicle 5.4x as long as wide, about 0.33x total length of scape, rest of scape about 5.0x as long as wide, longitudinally striate; pedicel longer than F1; F1 and F2 subequal, shorter than following funicle segments; F3–F8 more or less subequal, mps on F3 (0 or 1), F4 (1), F5 (2), F6 (2), F7 (2), F8 (2); clava with 8 mps, 3.4x as long as wide, a little shorter than combined length of F5–F8. Mesosoma ( Fig. 55). Pronotum 2-lobed (mediolongitudinally divided), not entire as drawn by Ogloblin (1936). Dorsellum rhomboidal. Forewing ( Fig. 56) 5.2–5.3x as long as wide; longest marginal seta about 0.5x maximum wing width. Forewing disc infumate, more so (as darker band) behind marginal vein and base of stigmal vein, bare behind submarginal vein, setose behind marginal vein, and with a small, elongate bare area just beyond stigmal vein. Hind wing ( Fig. 56) 31xas long as wide; disc mostly bare except for rows of setae along margins and several scattered setae, slightly infumate; longest marginal seta 3.8x maximum wing width. Metasoma longer than mesosoma. Petiole trapezoidal, a little wider than long. Ovipositor almost entire length of gaster, exserted beyond its apex by about 0.1x own length; ovipositor length: mesotibia length ratio 1.6:1.   FIGURES 57, 58.  Gonatocerus( Gonatocerus) stenopterus♂ (paralectotype): 57, antenna; 58, wings. Measurements (µm) of the lectotype.

Similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 57) with scape (without radicle) 2.9x as long as wide. Forewing ( Fig. 58) 4.9x as long as wide.   Diagnosis.  Gonatocerus( Gonatocerus) stenopterusis characterized by the female antenna ( Fig. 54) with mps on F4–F8 (and also sometimes on F3) and a narrow forewing (4.9–5.7x as long as wide) with a brown band behind the marginal vein and a small, elongate bare area on the disc just beyond the stigmal vein ( Figs 56, 58).   Distribution.NEOTROPICAL: Argentina.   Hosts.Unknown. 1639354013 1933-10-05 MLPA A.A.
