In this research, the current systematic status of endemic Anatolian species, Alburnus nasreddini, has been enlightened by making its morphological description and comparing it with the closest species, A. escherichii. This species has distinguished from the closest species, A. escherichii, by fever perforated scales along lateral line (44-48 vs. 46-53), dipper body depth (26.64 vs. 23.92% SL), shorter snout (25.54 vs. 27.55% HL) and larger eye diameter (31.22 vs. 27.88% HL). Our study has also examined the distribution area and habitat conditions of the species, clearly indicating that A. nasreddini distributed in only Akarcay basin (Eber, Aksehir and Karamik lakes; Selevir and Seyitler reservoirs; Kalli, Adiyan and Aksehir creeks) and Ilgin Lake Basin (Besgz Springs-Saraynu, Asagi Cigil Creek-Ilgin). Its observable population until very recently has disappeared from its type locality, Eber Lake, due to heavy pollution. Although its population present in Aksehir Lake is critically endangered due to the drought, presence of viable population in some dam lakes (especially in Selevir Reservoir) is considered as a promising picture with regard to the future of species.
