Achondrostoma oligolepis is a species of cyprinid fish. It is endemic to central and northern Portugal and known from between Limia and Tornada drainages, south of Douro.[1][3] It occurs in the lower stretches of rivers and streams.[1] It can grow to 25 cm (9.8 in) total length, although it typically measures about 15 cm (5.9 in) TL.[3]
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.[2]
