Metasoma (Figs 379 , 380 ). Elliptical in dorsal view, 1.9 x as long as wide and 1.3 x as long as mesosoma; first and second tergites coarsely longitudinally rugose; metasomal sutures medium-sized and deep; third tergite distinctly convex medially, 1.7 x longer than second tergite and laterally curved, in lateral view rather convex (Fig. 380 ), largely densely reticulate-rugulose and with satin sheen, lateral lamella narrow laterally and posteriorly, not protruding latero-apically and medio-apically truncate; ovipositor sheath parallel-sided and rather narrow apically, its visible part 0.15 x as long as fore wing and 0.3 x metasomal carapace and only apically with medium-sized setae; hypopygium setose and acute apically, without up curved triangle or spine apically (Fig. 380 ). Colour . Yellowish brown; apical antennal segments apically and apex of ovipositor sheath brown; stemmaticum dark brown; parastigma largely, veins 1-CU1, base of 2-CU1, cu-a, r, 2-SR, 3-SR, SR1 and 2-M of fore wing dark brown, other veins (including vein 1-M), and pterostigma basally and apically, pale yellowish; apical half of pterostigma partly dark brown; clypeus, mandible (except dark brown teeth), palpi, pronotal side, tegulum, mesoscutum medio-posteriorly, legs (but hind femur rather brownish except basally and hind tibia subbasally and apically dark brown), first and second tergites and metasoma baso-ventrally pale yellowish; humeral plate brownish; wing membrane below veins 1-&2-CU1 and below pterostigma brownish and remainder largely subhyaline. Male. Similar to female (including shape of hind femur and tibia); antennal segments slenderer and weakly serrate and with minor subapical protuberances; median width of temple 0.55 x width of eye in lateral view. Variations. Length of fore wing of ♀ 3.0-3.8 mm, of ♂ 2.8 mm; median width of temple 0.4-0.5 x width of eye in lateral view; dark part of hind tibia dark brown or brown; vein r of fore wing linear with vein 3-SR or rather angled, 0.8-1.1 x vein 3-SR; face often densely sculptured, rather matt or with satin sheen and dorsally often with fine median carina (Fig. 383 ), but female from UAE has face superficially sculptured, without median carina and shiny.
