Fore wing with two brownish bands, one behind basal part of marginal vein and second behind stigma, in macropterous form (Fig. 128) the second band converging towards the first and in brachypterous form (Fig. 126) the two bands joined posteriorly or not; fore wing setation brown. Hind wing hyaline. Metasoma with petiole as mesosoma (Fig. 125). Gaster (Fig. 118) yellow to yellowishbrown, with cercal region, tip of ovipositor sheaths and usually part of several tergites darker. Body setation whitish except for large, symmetrically arranged, black setae.
BODY LENGTH. 1.00– 1.75 mm.
HEAD. Clypeus almost smooth; apical margin slightly emarginated (Fig. 121). Lower face shallowly reticulate. Upper face reticulate, with reticulation becoming denser towards vertex (Fig. 120).

Antenna moderately clavate, with clava conspicuously asymmetric (Fig. 122). Upper face and vertex with ten large setae (Fig. 120). Head in dorsal view with width 2.10–2.25 × length (57:27) and in frontal view 1.1–1.2 × height (57:50). POL about 2.10–2.45 × OOL (15:7). Eye height about 1.3× length (29:23), 1.8–2.2× malar space (29:14) and 0.9–1.0 × scape length (29:30). Head width 0.85–0.90× length of pedicel plus flagellum (57:64). Fu1 length 1.0–1.5 × width (4:4); fu7 width 1.2–1.4× length (7.5:6.0); clava length 2.1–2.4 × width (19:8).
MESOSOMA. Pronotal collar narrower than mesoscutum, with six or seven large setae (Fig. 124). Mesonotum moderately setose dorsally (Fig. 124). Mesoscutum and axillae densely reticulate, dull (Fig. 124). Scutellum, including frenal area, reticulate, cells isodiametric to elongate (Fig. 124). Mesepisternum reticulate (Fig. 123). Lower mesepimeron smooth, upper mesepimeron transversally striate; mesepimeral sulcus as a rugose area (Fig. 123).

Differs from female mainly as follows. Body length: 0.75–1.60 mm. Head and mesosoma brown, except propodeum lighter (Fig. 129). Flagellum light brown to brown, slightly to conspicuously darker than scape and pedicel (Fig. 130). Fore wing with only first brownish band visible and this usually less distinct (Fig. 129). Gaster yellowish-brown, usually becoming darker towards tip, occasionally only tip dark (Fig. 129). Fu1 length 1.7–2.5 × width; length of pedicel plus flagellum 2.10–2.15 × as long as head width. Fore wing length 2.40–2.85 × width, row of admarginal setae sometimes longer. MV 5.0–5.5 × as long as SV and 5.0–6.2 × PV. Gaster (inflated) length 1.3–1.4 × width, gt1 occupying about one-third of gaster length.
Distribution
Mexico, USA.
Remarks
The only specimen from Mexico is not included in the type series because of its darker pedicel and legs, especially the hind tibia, which is dark brown. Females, and especially males, of this species are very similar to those of N. nearctica (see the key for main differences). Netomocera meridionalis sp. nov. seems confined to Florida and neighbouring states, except for three specimens collected in Missouri. Its area of distribution seems to be shared to a certain degree with N. nearctica (mostly Missouri, Georgia and Texas), the records of N. nearctica in Florida being very rare (see below). As for N. nearctica, this species has both brachypterous and macropterous females; the ratio of brachypterous versus macropterous females among the analyzed specimens was 28:6, without obvious intermediate forms and thus opposite of the situation found in N. nearctica, where the macropterous form seems dominant.
