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 ).

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 ). Mesosoma length 1.3–1.5 × width and 1.4–1.7 × height. Pronotal collar 0.55–0.60 × as long as mesoscutum and 0.85–0.95 × as wide as mesoscutum. Mesoscutum width 2.6–3.0 × length.

METASOMA. Petiole barely visible, transverse, smooth except for a few superficial longitudinal striae ( Fig. 185 ). Gaster ovate, length 1.7–1.8× width ( Figs 178 , 187 ); gt1 longest, length 0.80–1.15 × width, with hind margin straight to slightly emarginate; gt2–6 short; syntergum acutely pointed. Ovipositor sheaths distinctly protruding beyond apex of gaster. Cercal setae not surpassing apex of gaster.

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 ).
