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.

BODY LENGTH. 1.5–3.0 mm.
HEAD. Clypeus almost smooth; apical margin shallowly emarginate medially (

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 (

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.
