Taxonomy

This species was first described as ''Leuciscus macrolepidotus'' by Franz Steindachner in 1866, but this name was preoccupied by '' Leuciscus macrolepidotus'' Ayres, 1854. Therefore, a new replacement name ''Chondrostoma oligolepis'' was given to it in 2005. A later revision placed the taxon in another genus, giving the current combination in use.
