Oct. 31–1935 H. L. Dozier”, 2. [red] “ Gonatocerus portoricensis Dozier Paratype ♀ Type No. 51678 U.S.N.M.”; 1 ♂ (the allotype) on slide labeled: 1. “ Gonatocerus ♂ portoricensis Dozier Swept from roadside weeds. Ensenada, P. R. Dec. 5–1935 H. L. Dozier”, 2. [red] “ Gonatocerus portoricensis Dozier Allotype ♂ Type No. 51678 U.S.N.M.”. Other paratypes (6 females and 2 males), listed by Dozier (1937), were not examined.

Redescription. FEMALE (holotype, paratypes, and non-type specimens from Dominican Republic). Body length 781–1052 µm. Head and mesosoma dark brown to black, occasionally light brown to yellowish (six of the specimens from Dominican Republic); gaster mostly pale or, according to Dozier (1937), yellowish-orange in live specimens, with transverse brown bands on terga (Fig. 434); antenna brown to dark brown except scape and pedicel yellowish or light brown; legs light brown to brown.
Antenna (Fig. 433) with radicle about 0.2x total length of scape, remainder of scape 3.2–3.3x as long as wide; pedicel longer than F1; F2 longer than F1 (the shortest funicle segment) and about as long as F3 or F4; F5–F7 subequal in length, F8 a little shorter than F7; F1–F4 without mps, F5–F8 each with 2 mps; clava 3.7– 4.1x as long as wide, with 8 mps, about as long as combined length of F6–F8.
Mesosoma (Fig. 434) completely smooth and shiny dorsally. Dorsellum (Fig. 435) very narrow, at most 0.17x as long as wide. Propodeum (Fig. 435) with very short, inconspicuous submedian carinae (particularly in the dry-mounted specimens from Dominican Republic), extending from posterior margin at most 0.15x median length of propodeum. Forewing (Fig. 436) 3.0–3.3x as long as wide; longest marginal seta about 0.25x maximum wing width; disc with a slight brownish tinge throughout and a conspicuous narrow brown band behind stigmal vein, bare behind submarginal vein, with cubital row of setae complete and a few setae behind stigmal vein and apex of marginal vein, leaving a small bare area between base of marginal vein and cubital row of setae, densely setose elsewhere. Hind wing 16–17x as long as wide; longest marginal seta 1.9– 2.2x maximum wing width; disc mostly bare except for a row of setae along each margin and a few additional setae, with a very slight brownish tinge (almost hyaline).
Petiole about as wide as long. Gastral terga with transverse brown bands thin, less than half length of each tergum. Ovipositor rather short, about 0.6x length of gaster, not or barely exserted beyond apex of gaster; about 1.1x as long as mesotibia.
Measurements (µm) of the holotype. Total body length 1052; head 228; mesosoma 387; gaster 480; ovipositor 297. Antenna: radicle 32; rest of scape 121; pedicel 56; F1 33; F2 42; F3 42; F4 45; F5 54; F6 54; F7 52; F8 48; clava 160. Forewing 898:297; longest marginal seta 73. Hind wing 695:42; longest marginal seta 91.
MALE (allotype, Fig. 437). Body length 1144 µm. Similar to female except for normal sexually dimorphic features and the following. Antenna brown; scape, excluding radicle, 2.7x as long as wide. Forewing 3.3x as long as wide. Brown bands on gastral terga a little wider.
Diagnosis. Gonatocerus (Cosmocomoidea) portoricensis is a member of the ater subgroup of the ater species group. It is characterized by the combination of dorsellum very narrow, its length at most 0.17x its width, and propodeum with very short, thin, inconspicuous submedian carinae only at its posterior margin (Fig. 435). It is almost identical to the Nearctic species G. (Cosmocomoidea) fasciatus Girault, which has a much broader, rhomboidal dorsellum (2.36–3.6x as wide as long or length:width at least 0.28) (Huber 1988), and also to the southern Neotropical species G. (Cosmocomoidea) nigrithorax (Ogloblin), whose dorsellum length is at least 0.33x its width.
Distribution. NEOTROPICAL: Bahamas *, Cuba *, Dominican Republic *, and Puerto Rico (USA). Hosts. Unknown.
