This species is distinguished from other species of the O. angorae group by the following characters: with deeply emarginate caudal fin in which the shortest middle caudal-fin ray is 65-76% of the longest ray of the upper caudal-fin lobe (vs. moderately emarginate to almost truncate, 84-93 in O. anatolicus, 88-92 in O. angorae, 83-91 in O. eregliensis; 72-82 in O. O. germencicus, and 71-85 in O. isauricus); body depth slightly decreasing or almost uniform between the dorsal- and caudal-fin base, depth of caudal peduncle 85-92% of body depth at anterior-most dorsal fin base (vs. 68-79 in O. anatolicus, 70-83 in O. angorae and O. eregliensis, 72-82 in O. germencicus, 60-77 in O. isauricus), elongated blotches on flank being usually connected to the saddles on the back, meeting contralateral on flank (vs. usually disconnected), caudal peduncle depth 1.2-1.5 times in its length (vs. 1.5-1.8 in O. angorae and O. germencicus, 1.5-1.9 in O. eregliensis, 2.2-2.6 in O. isauricus); differs from O. anatolicus by having a narrower interorbital distance. 26-35% HL (vs. 33-40) and from O. angorae by lacking a depigmented stripe along the anterior part of the lateral line (vs. usually present) (Ref. 131061).
