A new roach material from Late Miocene of Odesa Pontian Lectostratotype (MN 13), Southern Ukraine is presented. Fragment of pharyngeal bone and isolated teeth are described as Rutilus sp. Presented specimen is characterized by massive ceratobranchiale, thick bulkheads between septum on the cavernous surface, and considerable pharyngeal teeth size. A review on the fossil fish remains of the Rutilus genus from numerous Miocene and Pliocene localities in Europe (Austria, Germany, Spain, Bulgaria and Netherlands) and Asia (Russia, Turkey, Kazakhstan and Armenia) is presented. Isolated pharyngeal teeth similar to those in Rutilus sp., are found in materials from several Late Miocene localities in Ukraine (e.g., Andriivka, Novoukrainka 1). Possibility of identification of the ichthyological material from Bezimenne locality (Late Pliocene, Khaprovian fauna) as R. sp. (contrary to Mylopharyngodon piceus Richardson, 1849) is discussed. General morphological similarity of this taxon to Rutilus frisii (Nordmann, 1840) can testify to their close phylogenetic relation.
