Holotype: (♀) Iran-West Azarbaijan, Mahabad, 17.v.2019, N 36°33´50´´ E 45°42´37´´, 1617 m, M. trap, S. Karimi. (HMIM).
Paratype: (♀) Georgia, Khvamli, 992 m asl., MT, 18–25.v.2021, leg. J. Japoshvili (Tbilisi).
Etymology: Mukriyan is the old name of a region in northwestern Iran that belongs to the collection locality of type materials.
Description: ♀: Body length 3.8–3.9 mm. Length of fore wing 3.0– 3.7 mm (Fig. 4A). Flagellum stout and filiform, with 12 flagellomeres; basal seven flagellomeres 1.3× longer than eye; preapical flagellomere 1.2× wider than long; apical flagellomere 2.3–2.4× as long as preapical one (Fig. 5E). Temple strongly and roundly narrowed behind eye. Distance between eye margin and lateral ocellus 1.5–1.7× ocellar diameter (Figs 5F & G). Face strongly convergent ventrally, minimally 0.6× as wide as maximal width of frons, smooth and shining, with fine sparse setiferous punctures. Malar space 0.45–0.50× as long as width of mandibular base. Genal carina reaching hypostomal carina far from mandibular base.
Mesoscutum smooth and shining, with fine rather dense punctures. Mesopleuron smooth and shining (Fig. 4B), with some longitudinal striae below subtegular ridge; median longitudinal groove about 0.8× as long as mesopleuron, with Ɐ strong transverse rugae in its posterior half. Metapleuron rugose, dull. Propodeum distinctly carinate, finely rugose. Area basalis and area superomedia confluent, together 1.7× longer than wide, with some coarse transverse rugae; anterior transverse carina (costula) reaching area superomedia in its middle. Area petiolaris 1.3× wider than long, almost smooth. Hind femur 4.6–4.7× longer than wide.
Areolet open laterally (3rs-m absent), vein 2rs-m 0.35–0.50× as long as part of vein M between veins 2rs-m and 2m-cu. Vein 1cu-a interstitial or slightly postfurcal. Postnervulus intercepted in or slightly behind its middle (Fig. 5H). Nervellus of hind wing slightly inclivous.
1 st tergite 3.2× longer than wide, with almost parallel sides; lateromedian and dorsolateral carinae complete. 2 nd tergite 1.15–1.20× longer than wide; 3 rd tergite 0.7–0.8H as long as wide. Ovipositor sheath 0.43–0.45× as long as hind tibia.
Color: black. Apical 0.3 of clypeus reddish; labrum yellowish. Scape and pedicel Ɐ reddish-yellow or reddish ventrally. Tegula ivory. 1 st tergite black. 2 nd tergite red in basal 0.3, black-brown apically; 3 rd tergite reddish, infuscate in apical 0.2–0.3; 4 th and 5 th tergite reddish basally and brown apically in holotype, brownish in paratype. 6 th and 7 th tergites brown. 2 nd to 5 th sternites cream-yellow, with brown lateral spots. Coxae black; fore and mid coxae reddish to yellow apically. Trochanters reddish, trochantelli yellow. Fore and mid femora reddish, with cream-yellow apical spots; fore and mid tibiae and tarsi red or reddish-yellow. Hind femur black; hind tibia blackish, with cream-yellow basally spot externally. Hind tarsus black. Wings hyaline or slightly infuscate; pterostigma brown.
Male unknown.
Taxonomical remark: Due to its short flagellum and ventrally narrowed face, this new species belongs to the O. superbum species-group (sensu Kasparyan 2011). It is similar to O. dodecameron Kasparyan, 2011, but can be differentiated by the following key:
1. Flagellum with 12 flagellomeres, seven basal flagellomeres combined 1.25× longer than eye. Minimal width of face 0.6× as wide as maximal width of frons. Fore trochanter yellow or reddish. Malar space 0.45–0.50× as long as width of mandibular base. Iran, Georgia .............................................................. O. mukriyana Riedel, nov. sp.
- Flagellum with 10–11 flagellomeres, seven basal flagellomeres combined 0.93× longer than eye. Minimal width of face 0.4× as wide as maximal width of frons. Fore trochanter black with yellow apex. Malar space 0.25× as long as width of mandibular base. Kyrgyzstan ............................................................ O. dodecameron Kasparyan, 2011
