Paratypes (18 ♀ + 6 ♂): 12 ♀ + 5 ♂ (BZL, RMNH), same label data as holotype; 1 ♀ (BZL), "TR., Konya, 30 km S [of] Aksehir, 24.vi.[19]98, J. Halada"; 4 ♀ + 1 ♂ (BZL, RMNH), "Turkey mer., Avgadi, 30 km NW of Erdemli, 1300 m, 20.vi.1996, P. Jelinek"; 1 ♀ (BZL), "NW Jordan, Irbid reg., Sarham vill., 25.iv.2003, I. Pljushtch".

Diagnosis.

Head distinctly convex dorsally in lateral view, in front of occipital carina without medio-posterior depression; face rather wide (Fig. 483); frons and vertex with satin sheen and densely very finely punctulate; occipital carina wide, smooth and lamelliform (Figs 478, 484, 492); propleuron 0.8 times as long as mesoscutum in front of tegulae and large coriaceous and with satin sheen; pronotal side very finely coriaceous but groove crenulate-rugose; antesternal carina narrow and non-lamelliform; middle and lateral lobe of mesoscutum very finely coriaceous and with satin sheen (Fig. 480); only mesopleuron ventrally conspicuously white pilose (Fig. 479); hind basitarsus entirely dark brown; hind tibia rather swollen and ventrally with ivory subbasal patch (Fig. 486); fifth sternite of female dark brown; apical 0.6-0.7 of hypopygium of female incised; ovipositor sheath 0.9-1.0 times as long as body, 1.4-1.5 times as long as metasoma, 4.3-5.0 times as long as hind tibia and 2.6-3.6 times as long as hind tibia and tarsus combined; ovipositor sheath dark brown apically, at most pale brown apical part of sheath 0.2 times as long as hind basitarsus; paramere of male black apically; third antennal segment of male 1.1 times as long as second segment, fourth segment twice as long as third segment and 1.1 times as long as second and third segments combined, fifth segment nearly as long as fourth segment (Fig. 490); hind tibia of male with subbasal ivory patch ventrally (Fig. 488); paramere black apically (Fig. 489); length of body 11-14 mm.

Description.

Female, length of body 14.2 mm (of fore wing 7.0 mm).

Head. Head distinctly convex dorsally in lateral view, in front of occipital carina without medio-posterior depression; face, frons anteriorly and temples inconspicuously pilose; occipital carina wide, smooth and lamelliform (Fig. 478); third and fourth antennal segments 1.4 and 2.3 times as long as second segment; face rather wide (Fig. 483); frons and vertex with satin sheen and superficially very finely punctulate; temples directly roundly narrowed behind eyes and resulting in subglobular head in dorsal view (Fig. 484); ventrally head not enlarged in anterior view, malar space 0.3 times length of pedicellus; inner tooth of mandible medium-sized.

Mesosoma. Length of mesosoma 1.9 times its height; propleuron 0.8 times as long as mesoscutum in front of tegulae, coriaceous, stout and with satin sheen; pronotal side mainly coriaceous except for crenulate-rugose grooves, sparsely pilose except posteriorly; side of pronotum with a rather small tooth antero-ventrally; antesternal carina narrow and non-lamelliform; middle and lateral lobe of mesoscutum very finely coriaceous and with satin sheen (Fig. 480); scutellum coriaceous; only mesopleuron ventrally white pilose (Fig. 479); propodeum with nearly complete median carina.

Legs. Length of hind femur, tibia and basitarsus 4.5, 4.6 and 6.4 times their width, respectively; hind tibia rather swollen and ventrally curved (Fig. 486); hind coxa mainly coriaceous; hind basitarsus moderately slender (Fig. 486).

Metasoma. Ovipositor sheath nearly as long as body, 1.4 times as long as metasoma, 4.7 times as long as hind tibia and 3.6 times as long as hind tibia and tarsus combined; pale brown apical part of ovipositor sheath 0.2 times as long as hind basitarsus.

Colour. Black; mandible (including base) and tegulae dark brown; bases of fore and middle tibiae and ventral subbasal patch of hind tibia ivory; apex of second and third tergite largely orange brown; remainder of legs and metasoma dark brown or blackish brown; pterostigma and veins dark brown; wing membrane subhyaline.

Male. Very similar to female, but mesoscutum superficially rugulose medio-posteriorly. Third antennal segment 1.1 times as long as second segment, fourth segment twice as long as third segment and 1.1 times as long as second and third segments combined, fifth segment nearly as long as fourth segment (Fig. 490); hind tibia and basitarsus as in female; apex of paramere black (Fig. 492).

Variation. Length of body of ♀ 11.4-14.2 mm (of ♂ 12.8 mm); mesoscutum of ♀ coarsely and densely punctate and medio-posteriorly rugose or rugulose; scutellum rather densely and coarsely punctate; ovipositor sheath 0.9-1.0 times as long as body, 1.4-1.5 times as long as metasoma, 4.3-5.0 times as long as hind tibia and 2.6-3.6 times as long as hind tibia and tarsus combined; pale brown apical part of ovipositor sheath 0.1-0.2 times as long as hind basitarsus or dark brown apically.

Distribution.

Jordan, Turkey.

Biology.

Unknown. Collected in April, June-July.

Etymology.

Named after “scorteus”, (Latin for “leathern”) and is used because of the very fine coriaceous mesoscutum.
