Dorsal spines (total): 7; Dorsal soft rays (total): 16-18; Anal spines: 1; Anal soft rays: 12 - 16. This species is distinguished from its congeners in freshwaters in Black Sea basin by the following characters: papillae in suborbital area 8-10 vertical rows; total scales in midlateral series 72-85; naked nape (Ref. 59043).
