Redescription. FEMALE (holotype). Head and mesosoma mostly brown, gaster mostly light brown; scape and legs light brown, flagellum brown.

Antenna ( Fig. 140 ) with radicle 0.3x total length of scape; pedicel much longer than F1; F1–F4 subequal in length, short, F5 a little longer, F1–F5 without mps; F6 of left antenna without mps and much shorter than F7, but with 2 mps on right antenna and just a little shorter than F7; F7 and F8 subequal, each with 2 mps; clava 4.2x as long as wide, with 8 mps, either equal to (left antenna) or a little shorter than (right antenna) combined length of F6–F8.

Mesosoma ( Fig. 141 ). Propodeum with 2 faint submedian lines; propodeal spiracle huge. Forewing ( Fig. 142 ) 3.3x as long as wide; longest marginal seta a little less than 0.5x maximum wing width; forewing disc slightly infumate, bare behind and just beyond venation except for several setae behind marginal and stigmal veins, setose in apical half or so. Hind wing ( Fig. 142 ) about 19x as long as wide; longest marginal seta 2.7x maximum wing width; disc bare except for a row of setae along each margin, almost hyaline.

Gaster longer than mesosoma; ovipositor very long, 2.5x as long as mesotibia, projecting strongly forward under mesosoma almost as far as procoxa, and not exserted beyond apex of gaster.

Measurements (µm) of the holotype. Total body length: 720; head: 97; mesosoma 276; gaster 358; ovipositor 479. Left antenna: radicle 39; rest of scape 86; pedicel 52; F1 21; F2 20; F3 21; F4 21; F5 30 [27 on the right antenna]; F6 39 [52 on the right antenna]; F7 57; F8 58; clava 154. Forewing 683:206; longest marginal seta 94. Hind wing 600:32; longest marginal seta 87.

MALE. Unknown.

Diagnosis. Gonatocerus (Gastrogonatocerus) spiracularis is characterized by the following unique combination: female antenna ( Fig. 140 ) with F1–F5 short, without mps, F6 with or without mps, F7 and F8 each with 2 mps; propodeal spiracle huge ( Fig. 141 ); ovipositor projecting strongly forward under mesosoma almost as far as procoxa.

Most specimens of G. spiracularis from the Hawaiian Islands lack mps on F6 of the female antenna ( Huber & Beardsley 2000) [as Gonatocerus sp. ( membraciphagus species group)] but all the other morphological features fit the species well.

Distribution. NEOTROPICAL: Argentina, Ecuador, and Mexico *. NEARCTIC*: Mexico *. OCEA- NIA*: Hawaiian Islands* (Hawaii, USA).

Hosts. Unknown.
