Özuluğ & Freyhof (2007) distinguished A. battalgilae from

A. attalus View in CoL

by having the anal-fin origin ½ scales behind the dorsal-fin base in individuals larger than 90 mm SL (vs. below dorsal-fin rays 7–8), 4 scale rows on the caudalfin base (vs. 3), 3 scale rows between the pelvic-fin origin and the lateral line (vs. 4), and a more slender body (body depth at dorsal 19–23% SL vs. 21–25, Table. 1 View TABLE 1 ). In individuals of both population groups larger than 90 mm SL, the anal-fin origin is situated below the dorsal-fin ray 7–8th or ½ scale behind the dorsal-fin base. In individuals smaller than 90 mm SL, the anal-fin origin is situated below the dorsal-fin ray 8th or 1–2.5 scales behind the dorsal-fin base. No difference between both population groups could be found and the differences originally proposed by Özuluğ & Freyhof (2007) could not be confirmed. This character is obviously much more variable than believed before. Also, we found no difference in the number of scale rows on the caudal-fin base (3–4 in A. battalgilae , vs. 3–4 in A. attalus ), and between the pelvic-fin origin and the lateral line (3–4 in A. battalgilae , vs. 3–4 in A. attalus ). Also, we found no difference in the body depth (body depth at dorsal-fin origin 19–23% SL, vs. 21–25, Table 1 View TABLE 1 ). Taking also the absence of differences in the molecular characters studied by Geiger et al. (2014), Mangıt & Yerli (2018) and Bektaş et al. (2020) into account, we treat A. attalus and A. battalgilae as conspecific.

As both species have been described in the same study by Özuluğ & Freyhof (2007), a First Reviser action is needed. The First Reviser action is the principle that in cases of conflicts between simultaneously published names, the first subsequent author can decide which has precedence ( ICZN 1999: Article 24.2). As First Revisers, we give precedence of A. attalus over A. battalgilae .
