This species was described from 1 female and 23 males, all syntypes, collected in Argentina in Loreto and San Ignacio (Misiones), [San Ramón de la Nueva] Orán (Salta), and Parque [Provincial] Aconquija (Tucumán); we accounted for all of them. Among the slides with Gonatocerus in Ogloblin’s collection in MLPA, there are 3 additional males collected prior to August 1936 on which the original manuscript name “ perplexus ” was not changed by him to “ pratensis ”. Apparently he did not count them as the original syntypes, and therefore we do not designate them as paralectotypes. These males are listed below under “Material examined” for G. (Lymaenon) pratensis. Additionally, 1 female on a slide in MPLA, labeled: 1. “ Gonatocerus pratensis [emn co] A. O. ♀ Loreto, Mis. Campo. A. A. O. 5.i.1933. Holotypus!”; 2. “3862”; 3. “not pratensis & not part of its type series J. Huber 2000 ”, does not fit the original description of G. pratensis (whereas the lectotype female does) but belongs instead to G. (Lymaenon) chrysis (Debauche).

Redescription. FEMALE (lectotype and non-type specimens). Body length 830–1150 µm. Body (Fig. 85) and appendages mostly brown to dark brown, scape and pedicel (partially) light brown, base of gaster brown, legs light brown to brown.
Antenna (Fig. 84) with radicle about 3.8x as long as wide, about 0.5x total length of scape, rest of scape 3.6–4.2x as long as wide, faintly striate; pedicel much longer than F1; F1 shorter than F2; F3 and F4 subequal, longer than F2 and shorter than following funicle segments; F5–F7 subequal, F8 a little shorter; F1–F4 without mps, F5–F8 usually each with 2 mps (F6 occasionally with just 1 mps); clava with 10 or 11 mps, 3.6–4.1x as long as wide, almost as long as combined length of F6–F8.
Mesosoma (Fig. 85). Mesoscutum, scutellum, and axillae with weak sculpture. Propodeum with faint submedian lines, the distance between them a little shorter basally than distally. Forewing (Fig. 86) 3.0–3.1x as long as wide; longest marginal seta 0.2–0.25x maximum wing width. Forewing disc almost hyaline (with a slight brownish tinge), almost bare behind submarginal vein, setose behind marginal vein (sparsely next to cubital row of setae). Hind wing (Fig. 87) 18–19x as long as wide; disc with 2 rows of setae along margins and setose apically, slightly infumate; longest marginal seta 2.6–2.7x maximum wing width.
Metasoma longer than mesosoma. Petiole trapezoidal, about 2.7x as wide as long. Ovipositor 0.7–0.8x length of gaster, exserted beyond its apex by at most 0.1x own length; ovipositor length: mesotibia length ratio 1.5–1.6:1. External plate of ovipositor with 4 distal setae.
Measurements (µm) of the lectotype. Body: total body length: 1150; head 148; mesosoma 418; petiole 24; gaster 560; ovipositor 464. Antenna: radicle 72; rest of scape 139; pedicel 58; F1 21; F2 34; F3 44; F4 45; F5 70; F6 70; F7 70; F8 64; clava 213. Forewing 1007:333; longest marginal seta 76. Hind wing 805:42; longest marginal seta 110.
MALE (paralectotypes and non-type specimens). Body length 700–930 µm [up to 1220 µm according to Ogloblin (1936)]. Similar to female except for normal sexually dimorphic features and the following. Antenna (Fig. 88) with scape plus radicle about 2.2x as long as wide, notably striate. Forewing (Fig. 89) about 3.2x as long as wide. Genitalia as in Fig. 90.
Diagnosis. Gonatocerus (Lymaenon) pratensis is characterized by the female antenna (Fig. 84) with 2 mps on F5–F8 and a wide forewing (3.0–3.1x as long as wide), with the area on the disc between the marginal vein and the cubital row of setae more or less setose (sparsely setose immediately next to the cubital row of setae) (Fig. 86). It differs from the much lighter colored G. (Lymaenon) chrysis (Debauche), which also has mps on F5–F8, by its wider forewing and also in having 10 or 11 mps on the clava (narrower forewing and only 6 mps on the clava in G. chrysis). Gonatocerus pratensis differs from the lighter colored G. (Lymaenon) litoralis (Haliday) in having usually 2 mps on F6 of the female antenna (female antenna of G. litoralis usually lacks mps on F6 but may occasionally have 1 mps in very large specimens).
