Alburnus escherichii, Steindachner, 1897

Bayçelebi, Esra, Turan, Davut, Kaya, Cüneyt & Freyhof, Jörg, 2020, Alburnus nasreddini, a synonym of A. escherichii (Teleostei: Leuciscidae), Zootaxa 4894 (1), pp. 123-132 : 129-131

Our examination revealed no morphological characters to distinguish A. nasreddini from

A. escherichii

( Table 1–3 )

and our morphological study supports the molecular hypothesis formulated by Bektaş et al. (2020) who suggests, that both species might be conspecific. We therefore treat A. nasreddini as a synonym of A. escherichii .
