Type material examined. Holotype female of Foersterella bonariensis  [ MACN] on slide labeled: 1. “ Försterella bonariensis Brèthes  type! B. As 22.II.1921 Hym. [ip]”; 2. “F 1”. The holotype is very poorly mounted laterally ( Fig. 218View FIGURE 218), complete but not cleared. The collection date indicated on the slide does not entirely match the published collection date of the holotype (23.ii.1921).

Lectotype female of Lymaenon necator  [MLPA], here designated to avoid confusion about the status of the type specimens of this species, on slide labeled: 1. “ Lymaenon necator  A. O. ♀ José C. Paz 24.ii.1939 Cynodon dactylon  . Typus! ♂”; 2. ‘3861”. The lectotype, although insufficiently cleared, is perfectly spread out, in very good condition, and mounted dorsoventrally. Paralectotypes [all MLPA]: 1 ♂ on the same slide and under the same coverslip as the lectotype; 1 ♀ and 1 ♂ on slide labeled: “ Lymaenon necator  A. O. 24.iii.1939. José C. Paz. Cynodon dactylon  . J. Ch.”; 1 ♀ and 1 ♂ on slide labeled: “ Lymaenon necator  A O ♀ José C. Paz [San Juan – co] 24.ii.1939. A. A. O.”; 1 ♂ on slide labeled: “ Lymaenon necator  A O [ip] ♂ José C. Paz 12.iii.1939. A-A-O.”; 1 ♀ on slide labeled: “ Lymaenon necator  ? [ip] A. O. ♀ San Juan A. O. Media Agua [ip] 8.ii.1939.”; 1 ♂ on slide [mounted together with a non-type female of G. (Lymaenon) pratensis (Ogloblin)  ], labeled: “ Lymaenon  necator  A. O? [ip] ♀ pratensis  A. O. San Juan. 8.ii.39 M. Agua A. O.” [the locality is Media Agua, San Juan Province, Argentina]; 1 ♂ on slide labeled: “ Lymaenon necator  ♂? [ip] A. O. San Juan 9.ii.1939. A. A. O.”; 1 ♀ on slide labeled: “ Gonatocerus necator A. Ogl.  [ip] ♀ Guatraché Pampa. 8.xii.1933 A. A. O.”; 1 ♀ on slide labeled: “ Gonatocerus  ? necator  [ip] ♀ Guatraché Prov. Pampa A O. 9.xii.1933 ”. This species was described from a syntype series of 6 females and 8 males. The whereabouts of the two remaining paralectotype males are unknown, but at least one was collected in La Plata (Buenos Aires Province) in Argentina.

Redescription. FEMALE (holotype of Foersterella bonariensis  , lectotype and paralectotypes of Lymaenon necator  , and non-type specimens from Argentina). Body length 860–1230 µm. Body brown to dark brown; radicle light brown, remainder of scape and pedicel brown to dark brown, flagellum dark brown; legs sometimes mostly light brown but usually mostly brown to dark brown except for mostly light brown tarsi.

Head as in Fig. 221View FIGURES 220 – 224. Antenna ( Figs 219View FIGURE 219, 220View FIGURES 220 – 224) with radicle about 0.3x total length of scape, rest of scape 2.5–3.0x as long as wide, longitudinally striate; pedicel much longer than F1; F1 and F2 short (F2 almost as long as F1) and without mps; F3 longer than F1 or F2 and a little shorter than F4, usually with 1 mps but occasionally without one; F4–F8 subequal in length (sometimes F7 slightly longer and F8 often slightly shorter) and each usually with 2 mps (F4 occasionally with just 1 mps); clava with 8 mps, 2.8–3.8x as long as wide, longer than combined length of F1–F4 and a little shorter than combined length of F5–F8.

Mesosoma ( Fig. 223View FIGURES 220 – 224). Mesoscutum and scutellum with faint sculpture; propodeum ( Fig. 222View FIGURES 220 – 224) with fine, often faint and inconspicuous, subparallel submedian carinae not extending to anterior margin of propodeum, otherwise smooth. Forewing ( Fig. 224View FIGURES 220 – 224) 3.2–3.5x as long as wide; longest marginal seta 0.2–0.25x maximum wing width; disc usually almost hyaline (with a slight brownish tinge), but sometimes with a more or less conspicuous, faint, darker band behind marginal and stigmal veins; mostly bare behind venation except for 9–12 setae just behind marginal and stigmal veins, with most of these more or less arranged in 1 or 2 irregular rows extending the length of marginal and stigmal veins, and densely setose elsewhere. Hind wing ( Fig. 224View FIGURES 220 – 224) 15– 18x as long as wide; disc with 2 rows of setae along margins, an additional row of setae between them, and an incomplete row of setae at apex; almost hyaline but with a slight brownish tinge apically; longest marginal seta 1.8–2.0x maximum wing width.

Petiole 1.5–1.6x as wide as long; gaster a little longer than mesosoma; ovipositor 0.7–0.9x length of gaster, barely exserted beyond apex of gaster by at most 0.1x own length; 1.2–1.7x as long as mesotibia.

Measurements (µm) of the holotype of G. bonariensis  . Total body length: 1292; mesosoma 523; gaster 572; ovipositor 409. Antenna: radicle 52; rest of scape 137; pedicel 55; F1 31; F2 27; F3 42; F4 48; F5 52; F6 47; F7 47; F8 45; clava 185. Forewing 1007:308; longest marginal seta 64.

MALE (paralectotypes of Lymaenon necator  and non-type specimens from Argentina). Body length 860– 1230 µm. Body dark brown, antenna brown, legs light to dark brown. Otherwise similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 225View FIGURES 225 – 227) with scape plus radicle about 2.1x as long as wide. Forewing ( Fig. 226View FIGURES 225 – 227) 3.3–3.4x as long as wide. Genitalia as in Fig. 227View FIGURES 225 – 227.

Diagnosis. The dark colored G. (Cosmocomoidea) bonariensis  is a member of the bucculentus  subgroup of the ater species group. It is characterized by the following unique combination: female antenna ( Fig. 220View FIGURES 220 – 224) with F1 and F2 short (F2 almost as long as F1) and without mps; occipital sulcus slightly higher than wide; and propodeum with submedian carinae fine, evanescent or apparently absent ( Fig. 222View FIGURES 220 – 224).

Distribution. NEOTROPICAL: Argentina, and Mexico * (Sinaloa). NEARCTIC: Canada ( Huber 1988) [as G. enicmophilus  ], and USA. Huber (1988) mentioned G. enicmophilus  from Mexico but without providing any information on its distribution there.

Hosts. Undetermined Cicadellidae  [as Bythoscopidae] and Delphacidae  ( Hemiptera  ) [as Araeopidae  ] ( De Santis & Esquivel 1967) [for G. necator  ].
