Redescription, male. Body length 8–10 mm, body width 2.8–3.5 mm. Body slender, shining, black, legs darkbrown, rarely elytra dark-brown. Head widest at level of eyes. Eyes large, convex. Ratio of head width at eyes to distance between eyes: 1.6. Genae angular basally and straight in anterior 2/3. Lateral margin of head between gena and clypeus with very small weak emargination. Punctation of head coarse and dense: diameter of punctures about twice as wide as distance between punctures, punctures often connected on sides. Head pubescent with short recumbent yellowish hairs. Antennae strongly elongated (reaching almost 1/2 of elytral length; elytra 1.15 × as long as antennae), with 4 apical antennomeres extending beyond base of pronotum. Pronotum cordiform, transverse (1.15–1.2 × as wide as long), widest before middle, 1.4 × as wide as head. Lateral margins weakly rounded or almost straight, widely emarginated laterally. Anterior margin weakly rounded; base weakly rounded at middle and weakly widely sinuate laterally. Anterior angles acute or right, distinct on apex, projected; posterior angles right, distinct on apex. All margins narrowly beaded. Disc regularly strongly convex. Punctation of disc coarse and dense; diameter of punctures visibly more than distance between punctures; punctures round. Hypomera with coarse longitudinal wrinkles, not flattened on lateral margins. Elytra convex, elongated (1.7 × as long as wide), widest at middle, 1.2 × as wide and 2.6 × as long as pronotum, 1.75 × as wide as head; width of elytral base subequal to width of pronotal base. Strial punctures merged in entire deep furrows. Elytral intervals weakly convex, with fine and sparse punctation (2–3 punctures in transverse distance of interval) and small distinct tubercles apically and laterally. Eighth intervals apically narrow and connected with margin of elytra and 2nd intervals. Epipleural carinae completely visible dorsally; epipleuron not reaching elytral apex. Ventral side. Meso- and metaventrite with short pubescence. Abdominal ventrites with fine dense punctation, regularly covered with short yellowish hairs. Ventrite 1 with dense hair brush in middle; ventrite 5 without depression, completely beaded. Legs slender. Inner side of femora pubescent basally and smooth and bare in apical 1/3. Protibiae straight, often weakly bisinuate on inner side, with 4–8 large and some small teeth; mesotibiae curved, with 3–8 small teeth; metatibiae straight, with small teeth or granules (rarely without teeth and granules in very small specimens). Trochanters with very dense hair brush.

Redescription, female. Body length 10.5–12 mm, body width 4–5 mm. Pronotum more transverse (1.3 × as wide as long), widest at middle. Elytra wider (1.6 × as long as wide), 1.4 × as wide as pronotum. Intervals flat, wide (4–5 punctures in transverse distance of interval). Abdominal ventrite 5 without depression. Antennae shorter (reaching 1/4 of elytral length), only 3 apical antennomeres extending beyond base of pronotum.

Bionomics. The species inhabits Quercus cerris (Abant Dağ) , Fagus and Picea orientalis (Yedigöller) , Quercus robur (Alem Dağ) at early night (20:00–23:00). Iranian population inhabit relic forests of Quercus castaneifolia ( Nabozhenko & Keskin 2013) . See also bionomics of O. operta .
