Type material. Holotype (♂) ( ZIN) and paratype (♀) (private collection of Sergey Kakunin): Iran, Kermanshah Prov., near Shamshir vill., 34.987951 N, 46.430794 E, 20–22.v.2015, leg. D.G. Kasatkin, S.O. Kakunin GoogleMaps   .

Description, male. Body length 12 mm, body width 4,3 mm. Body slender, dull, brown. Head widest at level of the eyes. Eyes large, convex. Ratio of head width at eyes to distance between eyes: 1.8. Genae convex with strongly rounded margin, outer margin of head between gena and clypeus without emargination. Transverse depression between frons and clypeus very deep, surface of clypeus is below the surface of frons. Punctation of head irregularly coarse and dense; punctation near eyes more coarse and dense (puncture diameter 1.5–2 × as wide as distance between punctures). Antennae long (reaching 1/3 of elytral length), with 4 apical antennomeres extending beyond base of pronotum; antennomer 3 1.8 × as long as antennomere 4. Pronotum weakly transverse (1.14 × as wide as long), widest at middle, 1.3 × as wide as head. Lateral margins weakly regularly rounded, weakly and shortly sinuate in base. Anterior margin stright; base weakly widely rounded. Anterior angles right, rounded on apex; posterior angles weakly obtuse, distinct on apex. All margins with narrow bead, base more widely beaded. Disc weakly convex with slightly depressed middle line. Punctation of disc fine, not dense; puncture diameters 3–4 × as short as distance between punctures. Hypomera not flattened on outer margins, with fine dense winkles. Elytra elongate (1.8 × as long as wide), widest behind middle, 1.27 × as wide and 2.65 × as long as pronotum, 1.7 × as wide as head. Elytral base little wider than base of pronotum. Strial punctures elongate, merged in interrupted deep furrows. Elytral intervals weakly convex, with fine and sparse punctation and distinct tubercles apically and laterally. Epipleural carinae completely visible dorsally, epipleura reaching sutural angles of elytra, not flattened (but thickened) on apex, narrow inner carinae of epipleura not reaching elytral apex. Lateral margins of elytra not sinuate or weakly sinuate on apex. Ventral side of body without pubescence. Abdominal ventrites 1–4 with regular, moderately dense and not coarse punctation; ventrite 1 without hair brush; ventrite 5 with finer and denser punctation and shallow round depression, without pubescence, not beaded on apex. Legs long, slender. Femora smooth and shining on inner side, not pubescent. Protibiae straight, regularly widened to apex, with regularly located along the entire length small 7 teeth; mesotibiae weakly curved and sharply widened on apex, without teeth or granules on inner side; metatibiae straight without teeth or granules. Trochanters with single long setae.

Description, female. Body length 11 mm, body width 4.2 mm. Body more robust. Pronotum widest before middle. Antennae shorter, their 3 apical antennomeres extending beyond base of pronotum, reaching 1/5 of elytral length. Elytra more convex, dorsal elytral carina not completely visible dorsally. Depression of abdominal ventrite 5 wide and occupies half of surface of the ventrite.

Etymology. Named in honour of Sergey Kakunin (Russian Entomological Society, Krasnodar), one of the collector of the species.

Diagnosis. The species is similar to O. cordiformis   sp. n. from which it differs by the brown body, not cordiform pronotum, the structure of aedeagus, absence of teeth on mesotibiae. O. kakunini   sp. n. differs from other species of the praelonga   species-group by protibiae regularly widened to apex with small teeth regularly located along the entire length.
