Type material examined. Holotype female [ MLPA] on slide labeled: “ Gastrogonatocerus pirigaster   [- gaster (emn) co ip and replaced above with - formis] A. Ogl. ♀ Chacra Yabebirí, San Ignacio , Misiones   . 5.iii.1951. Holotipo”. The holotype, although uncleared, is in good condition, complete, and mounted dorsoventrally.

Redescription. FEMALE. Body ( Figs 136, 137 View FIGURES 136 – 139 ) and appendages mostly brown except pedicel and tarsi light brown.

Antenna ( Fig. 138 View FIGURES 136 – 139 ) with radicle about 0.2x total length of scape; pedicel a little shorter than F1; all funicle segments much longer than wide, F1 and F8 the shortest, and F2 and F4 the longest among them; F1–F3 without mps; F4–F8 each with 2 mps; clava 4.4x as long as wide, with 8 mps, a little longer than combined length of F7 and F8.

Propodeum apparently smooth; propodeal spiracle small. Forewing ( Fig. 139 View FIGURES 136 – 139 ) 3.6x as long as wide; longest marginal seta about 0.25x maximum wing width; forewing disc bare except for 1–2 setae behind submarginal vein, setose and slightly infumate elsewhere (including behind marginal and submarginal veins), and with a narrow darker band behind stigmal vein. Hind wing ( Fig. 139 View FIGURES 136 – 139 ) 20x as long as wide; longest marginal seta 2.5x maximum wing width; disc bare except for a row of setae along each margin and a few scattered setae, infumate apically.

Gaster longer than mesosoma; ovipositor very long, 2.5x length of mesotibia, projecting strongly forward under mesosoma as far as procoxa, and exserted beyond apex of gaster by about 0.1x own length.

Measurements (µm) of the holotype. Total body length: 1341; head: 112; mesosoma 515; petiole: 58; gaster 656; ovipositor 1075. Antenna: radicle 39; rest of scape 136; pedicel 61; F1 70; F2 106; F3 97; F4 106; F5 103; F6 95; F7 91; F8 79; clava 200. Forewing 1304:363; longest marginal seta 94. Hind wing 1015:51; longest marginal seta 127.

MALE. Unknown.

Diagnosis. Gonatocerus (Gastrogonatocerus) piriformis   , known from the holotype only, is characterized by the following unique combination: female antenna ( Fig. 138 View FIGURES 136 – 139 ) with F1 a little longer than pedicel, all funicle segments much longer than wide, F4–F8 each with 2 mps; forewing disc setose behind marginal and stigmal veins and with a narrow dark band behind stigmal vein ( Fig. 139 View FIGURES 136 – 139 ); and ovipositor projecting strongly forward under the mesosoma as far as procoxa ( Figs 136, 137 View FIGURES 136 – 139 ).

Distribution. NEOTROPICAL: Argentina. Hosts. Unknown.
