This species is distinguished from other species of the O. angorae group by the following characters, but none is unique to the species: differs from O. anatolicus, O. angorae, O. eregliensis, O. isauricus, O. germencicus, O. nasreddini by having an almost uniform body depth between the dorsal- and caudal-fin bases, or body depth very slightly decreasing, with depth of caudal peduncle 87-97% 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, 70-86 in O. nasreddini); further differs by having a moderately deep caudal peduncle, its depth 1.3-1.6 times in 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, 1.5-2.1 in O. nasreddini), an emarginate caudal fin, with middle caudal-fin ray 71-80% of length of longest upper caudal-fin ray (vs. slightly emarginate or almost truncate, 84-93 in O. anatolicus, 88-92 in O. angorae, 83-91 in O. eregliensis and deeply emarginate, 65-76 in O. mediterraneus), no depigmented stripe along the anterior part of the lateral line (vs. usually present in O. angorae); differs further from O. mediterraneus by the tip of pectoral fin not reaching the pelvic-fin origin in male (vs. usually reaching) (Ref. 131061).
Occurs in the upper part of stream, with current and clear, cold water (Ref. 59043). Hides among the stones of the substrate. Stomach contents of a 6.32 cm SL female consists of aquatic insects larvae (Ref. 57755). Water abstraction may pose threat to its population (Ref. 59043).
