Achondrostoma oligolepis
Introduction '''''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. It occurs in the lower stretches of rivers and streams. It can grow to  total length, although it typically measures about  TL.
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.
