Cobitis saniae is distinguished from all other Cobitis species in the Caspian and Black Sea basin by having the base of the single lamina circularis widely connected to the pectoral-fin ray (vs. narrow connection). It is further distinguished from C. amphilekta by having a small focal zone in the sub-dorsal scales (about 1/10 or less of the maximum scale diameter vs. focal zone large, about 1/2 of the maximum scale diameter). Cobitis saniae is further distinguished from C. faridpaki by the zone between the eye and the opercle being strongly pigmented (vs. poorly pigmented or unpigmented) and it is further distinguished from C. avicennae from the Tigris River drainage by having a narrow, dorsal and ventral adipose crest on the caudal peduncle (vs. absent). Distribution. Cobitis saniae occurs from the Sefid River in Iran north-west to the Kura and Aras River drainages in Azerbaijan , Armenia and Turkey . We also found it in the middle Rioni River in the Georgian Black Sea basin (FSJF 3612). Remarks. Molecular data ( Fig. 1 ) as well as those shown by Jouladeh-Roudbar et al. (2017) and Perdices et al . (2018) , place C. saniae in the C. taenia species group close to C. avicennae and C. faridpaki . Based on DNA barcoding it is well separated from all other included Cobitis and by a minimum K2P distance of 2.7% to C. faridpaki . It is further supported as a PTP and mPTP entity. In the north of its range, C. saniae and C. amphilekta might occur in sympatry as both occur in the lower Kura and adjacent coastal wetland.
