Barbus oligolepis

Barbus oligolepis is a species of cyprinid fish endemic to Turkey where it is only known from fast flowing waters with substrates of stones or pebbles. This species can reach a length of 35 centimetres (14 in) SL.[1]

Taxonomic Issue[edit]

Oliotius oligolepis (Bleeker, 1853), a species of barb from Southeast Asia has at times been placed in the genus Barbus which would render the current species invalid as a junior homynym. However, since Bleeker's oligolepis species, originally in Capoeta, is currently placed in the genus Oliotius and before that in Puntius, Battalgil's oligolepis species is available and valid.[2]
