Diagnosis

Both sexes

Head yellowish ( Figs 192–193View Figs 191–195, 200View Figs 196–201). Macropterous. Clypeal margin shallowly emarginate ( Fig. 194View Figs 191–195). Upper face and vertex with ten large setae ( Fig. 193View Figs 191–195). Occiput margin blunt ( Fig. 193View Figs 191–195). Mesepimeral sulcus inconspicuous ( Fig. 196View Figs 196–201). Propodeum ( Fig. 198View Figs 196–201) 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. 198View Figs 196–201).

Female

Antenna ( Fig. 195View Figs 191–195) 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. 199View Figs 196–201).

Male

Body yellowish to brownish ( Fig. 200View Figs 196–201). Fu1 and fu10 (and occasionally fu9) usually at least slightly lighter than intermediate funiculars ( Fig. 201View Figs 196–201). Fore wing with at least one brownish spot behind basal end of marginal vein and usually with one or two more spots ( Fig. 200View Figs 196–201); apical basal cell densely setose apically (cf. Fig. 199View Figs 196–201).

Etymology

The name of the species (adjective) refers to the brownish stripes on the fore wing.

Head in dorsal view with width 2.1–2.4 × length (75:35) and in frontal view 1.10–1.25× height (75:60). POL 2.10–2.45 × OOL (21:10). Eye height 1.3–1.4 × length (38:30), 2.5–2.7 × malar space (38:14) and 0.90–1.05 × scape length (38:36). Head width 0.9–1.0 × length of pedicel plus flagellum (75:85). Fu1 length 1.3–1.5 × width (8:6); fu7 width 1.4–1.6 × length (10:7); clava length 2.0–2.4 × width (24:10).

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. 200View Figs 196–201). Flagellum usually with fu1 and fu10 distinctly lighter than the rest, yellowish to light brown ( Fig. 201View Figs 196–201). 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. 199View Figs 196–201) and a different colour of the antennae ( Fig. 195View Figs 191–195). In males, fu1 and fu10 are usually at least slightly lighter than fu2–fu9 ( Fig. 201View Figs 196–201), 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.
