Diagnosis
Both sexes
Head yellowish (Figs 192–193, 200). Macropterous. Clypeal margin shallowly emarginate (Fig. 194). Upper face and vertex with ten large setae (Fig. 193). Occiput margin blunt (Fig. 193). Mesepimeral sulcus inconspicuous (Fig. 196). Propodeum (Fig. 198) without a well-defined V-shaped area basally, with small smooth areas among carinae. Visible part of petiole very short, distinctly transverse, with more or less obliterate sculpture (Fig. 198).
Female
Antenna (Fig. 195) with basal funicular segments and clava pale yellow. Fore wing with three transverse brownish bands, the first apically within basal cell, the second behind parastigma and the third behind stigma (Fig. 199).
Male
Body yellowish to brownish (Fig. 200). Fu1 and fu10 (and occasionally fu9) usually at least slightly lighter than intermediate funiculars (Fig. 201). Fore wing with at least one brownish spot behind basal end of marginal vein and usually with one or two more spots (Fig. 200); apical basal cell densely setose apically (cf. Fig. 199).
Etymology
The name of the species (adjective) refers to the brownish stripes on the fore wing.

Legs with fore and hind coxae whitish, middle coxa brownish-yellow; trochanters and trochantelli as respective coxa; femora pale yellow; tibiae light brown; tarsi pale yellow, pretarsi dark brown. Fore wing (Fig. 199) with three brownish bands, the first apically within basal cell, the second behind parastigma and the third behind stigma, converging towards the second; setation brown. Hind wing hyaline. Metasoma with petiole as mesosoma (Fig. 198). Gaster (Fig. 191) yellowish, with cercal region and apical part of gt3 darker. Body setation whitish except large, symmetrically arranged, black setae.
BODY LENGTH. 1.5–3.0 mm.
HEAD. Clypeus almost smooth; apical margin shallowly emarginate medially (Fig. 194). Lower face shallowly reticulate. Upper face reticulate, with reticulation becoming denser towards vertex (Fig. 193). Scrobal depression densely reticulate. Occiput finely reticulate; margin blunt (Fig. 193). Toruli with lower margins slightly below lower margins of eyes (Fig. 192). Antenna moderately clavate, with clava slightly asymmetric (Fig. 195).

MESOSOMA. Pronotal collar narrower than mesoscutum, with six large setae (Fig. 197). Mesonotum moderately setose (Fig. 197). Mesoscutum and axillae densely reticulate, dull (Fig. 197). Scutellum, including frenal area, reticulate, cells isodiametric to elongate (Figs 197–198). Mesepisternum reticulate (Fig. 196). Lower mesepimeron smooth, upper mesepimeron transversally striate; mesepimeral sulcus indistinct (Fig. 196). Propodeum with dense pattern of carinae, interspaces wrinkled; nucha with lateral margins converging posteriorly (Fig. 198). Macropterous. Fore wing extensively bare in basal half, basal cell with a large patch of setae in apical third and with moderately large bare region (Fig. 199).

Male (Habitus: fig. 200)
Differs from female mainly as follows. Body length: 1.25–2.25 mm. Fore wing without brown spot on basal cell and one behind stigma greatly reduced to absent (Fig. 200). Flagellum usually with fu1 and fu10 distinctly lighter than the rest, yellowish to light brown (Fig. 201). Fu1 length 1.7–2.3 × width; length of pedicel plus flagellum 2.10–2.25 × as long as head width. Gaster (inflated) length 1.3–1.7 × width, gt1 occupying about one third to one half of gaster length.
Distribution
Bahamas, Brazil, Costa Rica, Panama, Venezuela.
Remarks
Netomocera virgata sp. nov. is similar to N. nearctica and N. meridionalis sp. nov.; the female differs from both species mainly in having a different fore wing colour pattern (Fig. 199) and a different colour of the antennae (Fig. 195). In males, fu1 and fu10 are usually at least slightly lighter than fu2–fu9 (Fig. 201), but sometimes only fu1, fu10, or none are different in colour. One male from Brazil (CNC) is excluded from the type series because it has only three setae apically in the basal cell; in other respects it is closer to N. virgata sp. nov. than to N. nearctica or N. meridionalis sp. nov.
