Narolskyia iranica nov.sp. (figs 10-14)

T y p e m a t e r i a l: Holotype: ♀ ̎ Iran: Markazi Prov., Arak, Haftad-Gholleh , Protected area, Chekab valley, 1872 m, N 34°08́06.5́́ E 50°10́59.6́́, Malaise trap, May 6-10, 2018, M. Parachami-Araghi ̎ (ZSM, Munich ). Paratype: ♀ with same data (Tehran).

Description: ♀: Body length 12 mm. Fore wing length 6.3 mm. Antenna with 39-40 flagellomeres; 1 st flagellomere 3.2x longer than wide, preapical flagellomere square. Head, seen from dorsal, 2.1x wider than long. Temple parallel behind eye, slightly narrowed apically. Distance of lateral ocellus to eye 1.5x ocellar diameter, distance between lateral ocelli 1.5x ocellar diameter.

Frons strongly impressed medially, with transverse striae above antennal grooves, coarsely punctate laterally. Outer orbit with scattered punctures. Face coarsely rugosepunctate, with tooth-like tubercle between antenna. Clypeus slightly bulging, with preapical transversal ridge and rounded apical margin. Malar space length 0.75x width of mandibular base. Mandible with two teeth, lower tooth larger than upper one.

Mesosoma covered with whitish hairs. Side of pronotum coarsely punctate dorsally, with fine striae in pronotal groove; collare with central groove and median longitudinal ridge. Notaulus not impressed. Mesoscutum mainly densely punctate, but punctation becoming scattered in apico-lateral parts. Mesopleuron and metapleuron coarsely and densely punctate, speculum smooth, mesopleuron with some fine striae frontal to speculum. Epicnemial carina narrow, almost reaching subtegular ridge; postpectal carina complete, slightly elevated. Scuto-scutellar groove with longitudinal striae. Scutellum strongly elevated, longer than wide, with complete lateral carina. Area basalis trapezoid, c.3x longer than wide. Area superomedia hexagonal, slightly longer than wide. Area petiolaris with transverse rugae. Costula indistinct. Legs slender; hind femur 5.1x longer than wide; hind tibia longer than hind femur. All claws with c.4 strong teeth.

Areolet of fore wing open distally. Nervulus interstitial or slightly antefurcal. Radial vein strongly sinusoid distal to areolet. Nervellus of hind wing intercepted in its apical 0.6,

discoidella weak. Metasoma strongly compressed laterally. 1st tergite c.3.1x longer than wide, with long

glymma, coarsely striate. 2 nd tergite 2.1x longer than wide, coarsely striate. Following tergites longer than wide, with fine granulation and scattered very fine setiferous punctures. Apical margin of 6 th tergite with median notch. Ovipositor 2.3x longer than hind tibia, strongly sinusoid in its apical 0.2.

Color: Black. Palps and mandible centrally reddish. Inner orbit (widened opposite to antenna), stripe on dorsal half of outer orbit, hook-shaped anterolateral mark on mesoscutum, tegula and scutellum ivory. 1 st and 2 nd tergites black; 3 rd to 5 th tergites red, epipleura more or less brownish; 6 th tergite red, with median brown stripe. Coxae and trochanters black; legs otherwise red; femora with ivory spots apically; fore and mid tibiae with ivory stripes externally; hind tibia blackish internally and with subbasal blackish ring, ivory externally; hind tarsus black. Wings hyaline, pterostigma brownish, pale proximally.

♂ unknown. Remark: Although this new taxon has an apical notch of 6th tergite which is typical for

Celor KOKUJEV, we have no doubt to include it in the genus Narolskyia KOÇAK & KEMAL. Its large size, compressed metasoma, wing venation, structure of propodeum and 1 st tergite and form of ovipositor resembles the other known species of this genus, Narolskyia chosrov (NAROLSKY). It can be differentiated from N. chosrov by the notched 6 th tergite, larger ocelli, shorter ovipositor, and reddish apical tergites.
