Squalius cephaloides, a synonym of Squalius cii (Teleostei: Leuciscidae).

The two species hypothesis for S. cephaloides and S. cii, both occurring in the southern Marmara Sea basin, is tested. Our results suggested that there are no morphological and molecular characters to support this hypothesis, and we treat Squalius cephaloides as a junior synonym of S. cii.

Alburnus battalgilae, a synonym of A. attalus (Teleostei: Leuciscidae).

Alburnus battalgilae zulu Freyhof, 2007 from the Gediz River drainage in western Anatolia is a junior synonym of A. attalus zulu Freyhof, 2007, from the adjacent Bakr River drainage. We were unable to confirm the morphological differences originally proposed. As both species have been described in the same publication, as First Reviewers, we prioritise of A. attalus over A. battalgilae.
