( Figs 339–345 )

Paratypes: DOMINICAN REPUBLIC. DUARTE, 2 km NE of San Fransisco de Macorís, Reserva Científica Loma Quita Espuela , 300 m, 18.iii.1991 [1 ♀ on point, CNCI] . PEDERNALES, Sierra de Bahoruco: Alcoa Road (km 25), 700 m, 18.i.1989, L. Masner (dry montane forest) [3 ♀, 3 ♂ on points, CNCI; 1 ♂ on slide, UCRC] . “ Las Abejas ”, 1300 m, 17–19.i.1989, L. Masner (cloud forest) [2 ♀ on points, CNCI, UCRC] .

Description. FEMALE (holotype and paratypes). Body length (paratype) 2047 µm. Body and appendages generally yellowish-brown except trabeculae dark brown, F1–F5 brown, F6 and F7 whitish or yellowish, and F8 and clava dark brown.

Antenna ( Fig. 339 ) with radicle about 0.25x total length of scape; rest of scape about 3.7x as long as wide, faintly striate; pedicel very small, much shorter than F1; F1 the longest funicle segment, a little longer than F2, neither segment with mps; F3–F8 each progressively a little shorter than preceding funicle segment, mps on F3 (2), F4 (2), F5–F8 (each with at least 1, possibly with 2 mps); clava with 8 mps, about 3.9x as long as wide, a little shorter than combined length of F5–F8.

Mesosoma ( Fig. 340 ). Pronotum entire. Pronotum, mesoscutum, and scutellum with weak reticulate sculpture; dorsellum ( Fig. 341 ) smooth, subtrapezoidal; propodeum ( Fig. 341 ) with rows of punctures extending to its anterior margin, more numerous laterally. Forewing ( Fig. 342 ) about 3.9x as long as wide; longest marginal seta about 0.2x maximum wing width; disc bare behind venation except for several setae just behind marginal and stigmal veins, and slightly, uniformly infumate. Hind wing about 19x as long as wide (widest part of disc not at apex of venation but beyond it); disc slightly infumate, with a row of setae along each margin and additional, 2 irregular rows of setae in the middle; longest marginal seta 1.6–1.7x maximum wing width. Metacoxa strongly reticulate, metafemur less so.

Metasoma ( Fig. 340 ). Petiole reticulate, about 7x as long as wide. Gaster shorter than mesosoma. Ovipositor short, about 0.6x length of gaster, not exserted beyond gastral apex; ovipositor length: mesotibia length ratio 0.65:1.

Measurements (µm) of the holotype. Body (without head) 1790; mesosoma 775; petiole 430; gaster 615; ovipositor 424. Antenna: radicle 61; rest of scape 205; pedicel 73; F1 157; F2 148; F3 136; F4 118; F5 112; F6 97; F7 91; F8 85; clava 321. Forewing 1814:464; longest marginal seta 91. Hind wing 1396:73; longest marginal seta 121.

MALE (paratypes). Body length 1915–2047 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna ( Fig. 343 ) with scape light brown, remainder brown to dark brown; gastral terga with light brown or brown transverse bands. Forewing ( Fig. 344 ) 3.8–3.9x as long as wide. Genitalia as in Fig. 345 .

Diagnosis. Gonatocerus (Cosmocomoidea) hispaniolus sp. n. is a member of the masneri species group. It differs from G. (Cosmocomoidea) masneri Yoshimoto , the only other known species from the same species group, in having F6 and F7 of the female antenna whitish ( Fig. 339 ).

Etymology. The species name is derived from Hispaniola (from Spanish, La Española), a major island in the Caribbean, comprising the Dominican Republic and Haiti.

Hosts. Unknown.
