Species

In FishBase (2022), nine species are included in the genus:^[1]

• Rutilus caspicus (Yakovlev, 1870) (Caspian roach)
• Rutilus frisii (Nordmann, 1840) (Black sea roach)
• Rutilus heckelii (Nordmann, 1840)
• Rutilus kutum (S. N. Kamensky, 1901) (Caspian kutum)
• Rutilus meidingeri (Heckel, 1851)
• Rutilus pigus (Lacépède, 1803) (Pigo)
• Rutilus rutilus (Linnaeus, 1758) (Common roach)
• Rutilus stoumboudae Bianco & Ketmaier, 2014^[2]
• Rutilus virgo (Heckel, 1852) (Cactus roach)

In a phylogeographic study, Levin et al. (2017) argue that the Ponto-Caspian taxa including R. caspicus, R. heckelii and R. stoumboudae could represent a single widespread species whose range extends to Siberia, to be named Rutilus lacustris, whereas R. kutum is included in R. frisii. ^[3]

The genera Leucos and Sarmarutilus have been recently separated from Rutilus and are closely related to it.^[2]
