Some recent works have proposed that Capoeta ekmekciae from the Çoruh River and C. capoeta from the Kura-Aras River system are synonyms based on molecular data, which prompted this study to compare their morphometric, meristic and molecular data to investigate this hypothesis. Based on the results, the C. ekmekciae form displays morphometric and meristic traits quite similar to the C. capoeta form. Since there are no diagnostic traits to distinguish these two allopatric species from each other and they share identical cytb gene, we treat C. ekmekciae as a junior synonym of C. capoeta.
Keywords: Kura-Aras basin; cytochrome b; interspecific variation; Çoruh river.
