No types known. Syntypes : ZIN 3008–09 (3). Leuciscus rutilus var. caspicus Yakovlev [V. E.] 1870: 103 [3]; Type locality: Volga River Delta, Russia . Syntypes : whereabouts unknown.

G.] & Ketmaier [V.] 2014: 398; Type locality: Lake Volvi, Greece . Holotype : IZA 02107A. Paratypes : IZA 02107B (11). Common name : Pr: Kolmeh, En: Caspian roach. Meristic characters : D: II–V 8–12 (9), A: II–IV 8–12, P: 14–18, V: 7–9, GR: 9–17 (10–14), LL: 39–48, TV: 37–42. Diagnosis : Similar to R. frisii but can be distinguished by having lower scale count (less than 50) and the posterior part of the swim bladder being rounded rather than pointed. Distribution : Caspian Sea basin ( Fig. 261 ). Found in Sefidrud, Gorgan rud, Aras, Atrak River and Anzali Wetland. Taxonomy : Berg (1949) placed lacustris in Rutilus rutilus (Linnaeus 1758) as a subspecies. Kottelat (1997) synonymised with Rutilus rutilus but Levin et al. (2017) regard as full and valid species. Conservation : IUCN: Not Evaluated, PC: Least Concern. Rutilus lacustris is a widespread species with no known widespread threats. Therefore, we classified it as Least Concern.
