Eagderi, Soheil, Nikmehr, Nasrin & Freyhof, Jörg, 2019, Alburnus zagrosensis, a junior synonym of Alburnus sellal (Teleostei: Leuciscidae), Zootaxa 4652 (2), pp. 367-374 : 371-373

Alburnus sellal

is a widespread species occurring in the Qweik River drainage in Turkey and the Persian Gulf basin in Turkey, Iraq, Syria and Iran ( Berg 1949, Özuluğ & Freyhof 2007, Freyhof et al. 2018). Alburnus zagrosensis was described from the Karun River drainage, which is a tributary of the lower Arvand River, the joint lower section of the Euphrates and Tigris. Alburnus sellal is widespread in the Karun River and its range is directly confluent with that of A. zagrosensis . The existence of minor molecular and morphological differences between populations of widespread freshwater fish species, including branched dorsal, anal and pelvic fin ray counts, colour pattern and adult size, is a well-studied phenomenon ( Marcil et al. 2006). Although a single individual of A. zagrosensis differed from A. sellal in the number of scales between the lateral line and the dorsal-fin origin, we see no reason to consider A. zagrosensis as a valid species. In addition, data published in other studies confirm that A. sellal exhibits an even wider range in meristic characters than shown in the present study, all of which overlap with those of A. zagrosensis ( Jalili et al. 2015, Mousavi-Sabet et al. 2015, Freyhof et al. 2018).

As we were unable to find any differences between A. zagrosensis and A. sellal , we see no argument to treat A. zagrosensis as a valid species. Therefore, we treat A. zagrosensis as junior synonym of A. sellal .
