(Figs 73–76)

Gonatocerus flaviventris Dozier 1932: 82 –83. Type locality: Sarthe, Haiti. Gonatocerus (Gonatocerus) flaviventris Dozier: De Santis 1979: 365 (catalog). Gonatocerus flaviventris Dozier: Yoshimoto 1990: 40 (list).

Type material examined. Holotype female [USNM] on slide labeled: 1. “ Gonatocerus flaviventris Dozier Reared from Lignum-vitae infested with Aleurothrixus floccosus (Mask.) Sarthe, Haiti March 5–1931 H. L. Dozier”; 2. [red] “ Gonatocerus [Ooctonus – co] flaviventris Dozier ♀ Type No. 65498 U.S.N.M.”. 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.

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 21x as 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) cubensis Dozier, 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).
