Description

Female (habitus: Figs 178, 187)

COLOUR. Head( Figs179–180) usually with more or less distinct dark green to bronze reflections.Mandibles reddish-yellow, teeth darker. Antenna ( Fig. 182) with scape pale yellow to reddish-brown; pedicel pale yellow to brown; funicle uniformly brown or basally paler; clava, especially ventrally, slightly paler than funicle. Mesosoma ( Fig. 183–185) reddish-yellow to reddish-brown. Legs reddish-yellow, except for brownish tips, or hind coxa lighter. Fore wing ( Fig. 186) of macropterous and submacropterous forms usually with two large brownish spots, a larger one in middle of wing below marginal vein and a smaller one in apical quarter, the latter sometimes appearing divided into two smaller spots; setation brown. Metasoma with petiole as mesosoma ( Fig. 185); gaster ( Figs 178, 187) reddish-yellow to reddish-brown in basal half and light brown to dark brown in apical half; gt1 usually with two darker spots anterolaterally. Body setation pale except for several large, symmetrically arranged, dark brown setae.

BODY LENGTH. 1.6–2.1 mm.

HEAD. Clypeus virtually smooth; apical margin slightly produced ( Fig. 181). Lower face below toruli striate-reticulate, piliferous punctures mostly indistinct. Upper face including vertex densely but finely reticulate, piliferous punctures slightly visible ( Fig. 180). Scrobes deep, reticulate; parascrobal region mostly without elongate cells ( Fig. 179). Occiput coriaceous-alutaceous; margin blunt ( Fig. 180). Toruli with lower margins below lower margins of eyes ( Fig. 179). Antenna moderately clavate, with clava conspicuously asymmetric ( Fig. 182). Upper face and vertex with eight large setae. Head width about 2.2× length in dorsal view and 1.15–1.30 × height in frontal view. POL 2.2–2.3× OOL. Eye height 1.3– 1.4× length, 2.2–2.3 × malar space and 1.0–1.2× scape length. Head width 1.0–1.1 × length of pedicel plus flagellum. Fu1 length 1.3–1.8 × width; fu7 width 1.1–1.5 × length; clava length 1.8–2.0 × width.

MESOSOMA. Moderately setose dorsally ( Fig. 184). Pronotal collar virtually as wide as or slightly narrower than mesoscutum, with six large setae ( Fig. 184). Mesoscutum and axillae with extremely fine reticulation, appearing almost smooth ( Fig. 184). Scutellar disc with sculpture as mesoscutum and longitudinally striate-reticulate on frenal area ( Figs 184–185). Mesepisternum mainly weakly reticulate, almost smooth dorsally ( Fig. 183). Mesepimeron smooth; mesepimeral sulcus indistinct ( Fig. 183). Propodeum mainly smooth, with intricate pattern of carinae defining a central V-shaped area, interspaces smooth to slightly wrinkled ( Fig. 185). Macropterous, submacropterous ( Fig. 178) or brachypterous ( Fig. 187). Macropterous and submacropterous forms with fore wing uniformly and densely setose except for moderately large, elongate bare region some distance behind parastigma and basal half of marginal vein ( Fig. 186). Brachypterous form with fore and hind wings reduced and represented by stumps, venation vestigial; fore wing with rounded apex not reaching posterior margin of propodeum; setation absent except in apical third ( Fig. 188).

Male (habitus: Fig. 189)

Differs from female mainly as follows. Body length: 1.0– 1.8 mm. Head sometimes without distinct metallic reflections ( Fig. 189). Flagellum uniformly dark brown to black ( Fig. 190). Mesosoma usually dark brown to black ( Fig. 189), occasionally with reddish pronotal collar, propodeum and pleura. Gaster dark brown to black ( Fig. 189) or with basal half lighter, light brown to reddish-brown. Propodeum more uniformly sculptured, mostly without a well-defined V-shaped area. Fu1 length 1.7–2.0 × width, other funicular segments subequal in length to fu1; combined length of pedicel plus flagellum 2.0–2.5× head width. Gaster (inflated) shorter than mesosoma, length 1.5–1.6 × width.

Distribution

China, Croatia, Czech Republic, Moldavia, Montenegro, Romania, Serbia, Slovakia ( Noyes 2018); Bulgaria, France, Greece, Italy (new records).

Remarks

Females of Netomocera setifera are distinct from those of all other species with a reduced petiole in having a well defined V-shaped area on the propodeum ( Fig. 185). Together with males, they display mesosomal colour variation, which can range from yellowish to brown. Except for N. rufa , both sexes are also unique in having a long and wide pronotal collar ( Figs 183–184).
