The holotype is complete, somewhat uncleared, mounted dorsoventrally.   Redescription.FEMALE. Head and mesosoma ( Figs 73, 75) mostly dark brown, gaster light brown basally, distal gastral terga dark brown; antenna brown (scape and pedicel slightly lighter than flagellum); legs light brown to brown. Antenna ( Fig. 74) with radicle about 0.4x total length of scape, rest of scape 2.5x as long as wide; pedicel longer than F1; F1–F6 short, subequal (F2 a little shorter and F6 a little longer), shorter and narrower than F7 or F8; mps only on F7 (2) and F8 (2); clava with at least 8 visible mps, 2.1–3.7x as long as wide, a little shorter than or subequal to combined length of F5–F8.   FIGURE 73.  Gonatocerus( Lymaenon) flaviventris♀ (holotype): habitus. Forewing ( Fig. 76) 2.8x as long as wide; longest marginal seta about 0.33x maximum wing width. Forewing disc hyaline, bare behind submarginal vein, setose behind and beyond marginal vein. Hind wing 21xas long as wide; disc hyaline, bare except for rows of setae along margins and a few setae at apex; longest marginal seta 3.2x maximum wing width. Metasoma ( Fig. 73). Ovipositor 0.8x length of gaster, not exserted beyond its apex; ovipositor length: mesotibia length ratio 1.2:1. Measurements (µm). Body: 683; head: 167; mesosoma 258; petiole 21; gaster 273; ovipositor 227. Antenna: radicle 52; rest of scape 82; pedicel 45; F1 26; F2 18; F3 24; F4 24; F5 27; F6 30; F7 39; F8 39; clava 126. Forewing 633:224; longest marginal seta 76. Hind wing 512:24; longest marginal seta 76. MALE. Unknown.   Diagnosis.  Gonatocerus( Lymaenon) flaviventris, known only from the female holotype, is characterized by its short antenna ( Fig. 74) with mps on F7 and F8 only, and also by its generally dark brown head and mesosoma ( Figs 73, 75). It is most similar to  G.( Lymaenon) cubensisDozier, which has a relatively more slender antenna ( Fig. 69) and a light brown mesosoma ( Fig. 70). Both species are very similar to some small individuals of  G.( Lymaenon) litoralis(Haliday)that lack a mps on F5 of the female antenna, but the forewing of the latter has several setae behind the submarginal vein next to the base of the marginal vein ( Fig. 80).   Distribution.NEOTROPICAL: Haiti.   Hosts.Unknown ( Dozier 1932).
