This species is distinguished from other species in the Aegean and adjacent basins by the following set of characters: body with a marbled pattern (vs. more or less irregularly shaped dark brown or pale brown blocks or bars on the flank in O. germencicus, O. theophilii, O. eliasi, O. simavicus, O. fatmae, O. angorae); with a deeper caudal peduncle, its depth 1.0-1.3 in its length (vs. 1.3-2.2, except O. theophilii); wider interorbital distance, 28-36% HL (vs. 20-28, except O. germencicus, O. angorae); differs from O. marmaraensis by the presence of an axillary lobe at the base of the pelvic fin (vs. absent) and has a narrower median incision in the upper lip (Ref. 132448). |
