( Figs 17–21 View FIGURES 17, 18 View FIGURES 19 – 21 )

Lymaenon bonaerensis Ogloblin 1939: 246 –248 + plate (lámina) V (illustrations). Type locality: José C. Paz, Buenos Aires, 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. “ Lymaenon bonaerensis A. O. ♀ José C. Paz 24.ii.1939. Cynodon dactylon J. Ch. Typus – fig.”; 2. ‘3841/1”.

The lectotype is in very poor condition, uncleared, mounted dorsoventrally right under a crack in the coverslip ( Fig. 17 View FIGURES 17, 18 ), with the wings, one antenna, and a protarsus detached; the other antenna and one leg are apparently missing. The published collection date of the two female syntypes (24.iii.1939) contradicts the collection date on the lectotype slide (24.ii.1939). The second specimen (paralectotype) is not in MLPA and its whereabouts are unknown.

Redescription. FEMALE (lectotype and non-type specimens). Vertex and most of gaster brown to dark brown; rest of head and mesosoma light brown to brown; scape, pedicel, petiole, base of gaster, and legs light brown; flagellum dark brown.

Antenna ( Fig. 19 View FIGURES 19 – 21 ) with radicle about 0.4x total length of scape, rest of scape about 3.3x as long as wide, lightly striate; pedicel longer than F1; F1–F6 narrower than F7 or F8, F2 and F3 subequal, slightly longer than F4, F5, and F6; F1–F6 without mps, F7 and F8 each with 2 mps; clava with 6 mps, 3.9x as long as wide, slightly shorter than combined length of F5–F8.

Mesosoma ( Fig. 20 View FIGURES 19 – 21 ) with dorsellum rhomboidal. Propodeum with 2 submedian carinae hardly visible, as incomplete, very fine lines. Forewing ( Figs 18 View FIGURES 17, 18 , 21 View FIGURES 19 – 21 ) 4.9–5.0x as long as wide; longest marginal seta about 0.6x maximum wing width. Forewing disc slightly infumate throughout, bare behind submarginal vein, sparsely setose (almost bare) between marginal vein and cubital row of setae; remainder of disc densely setose. Hind wing 25–28x as long as wide; disc bare except for rows of setae along margins, slightly infumate apically; longest marginal seta 3.7–3.8x maximum wing width.

Metasoma ( Fig. 20 View FIGURES 19 – 21 ) with petiole short, a little wider than long, trapezoidal. Ovipositor 0.6–0.7x length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio about 1.1:1.

Measurements (µm) of the lectotype. Body: total body length: 984; head 166; mesosoma 351; metasoma 467. Forewing 1015:203; longest marginal seta 115. Hind wing 756:27; longest marginal seta 100.

Description. MALE (previously unknown, 2 non-type specimens from Uruguay). Body length 820–850 µm. Very similar to female except for normal sexually dimorphic features; forewing about 5.3x as long as wide.

Diagnosis. Gonatocerus (Gonatocerus) bonaerensis is characterized by the female antenna ( Fig. 19 View FIGURES 19 – 21 ) with mps on F7 and F8 only, and a narrow forewing (4.9–5.0x as long as wide). The forewing disc has an elongate bare area between the marginal vein and the cubital row of setae ( Fig. 21 View FIGURES 19 – 21 ).

Distribution. NEOTROPICAL: Argentina, and Uruguay *.

Hosts. Unknown.
