Except the colour pattern, <i>A. kotschyi</i> is distinguished from <i>A</i>. <i>caeruleus</i> by having a more slender body (body depth at dorsal-fin origin 21–26% of SL vs. 26–34%) and having less branched anal-fin rays (9½–11½ vs. 13½–17½) and the ventral keel exposed 3–10 scales in front of anus (vs. scaleless). <i>Alburnus kotschyi</i> is distinguished from <i>A</i>. <i>orontis</i> by having less branched anal-fin rays (9½–11½ vs. 12½–15½), the ventral keel exposed 3–10 scales in front of anus (vs. keel exposed 0–2 scales) and a soft last simple dorsal-fin ray (vs. stiff in <i>A. orontis</i>). <i>Alburnus kotschyi</i> is distinguished from <i>A. heckeli</i>, <i>A. sellal</i>, <i>A. tarichi</i> and <i>A. timarensis</i> by having 49–59 total lateral line scales (vs. 77–93 in <i>A. heckeli</i>, 66–89 in <i>A. sellal</i>, 54–72 in <i>A. timarensis</i>, 70–93 in <i>A. tarichi</i>) and 9–12 gill rakers on first gill arch (vs. 13–17 in <i>A. timarensis</i>). <b>Description.</b> See Figure 1 +3 for general appearance of the neotype (IUSHM 37900-253) and other individuals. Body elongate, compressed. Dorsal, ventral profiles convex. Head short, interorbital area convex. Mouth oblique, lower jaw slightly projecting beyond upper jaw. Snout slightly pointed, its length smaller than interorbital distance, greater than eye diameter. Caudal peduncle depth 1.8–2.5 times in its length. Dorsal-fin margin straight, anal-fin margin slightly convex anteriorly, slightly concave posteriorly. Distance between pelvicfin origin and dorsal-fin origin equal to about ½ of pelvic-fin length. Anal-fin origin one scale behind last dorsal-fin ray. Keel between anus and pelvic-fin base exposed for 3–10 scales in front of anus. Maximum size 170 mm SL. Dorsal fin with 3 simple and 7½ (1)–8½ (75) branched rays. Anal fin with 3 simple and 9½ (13), 10½ (48) and 11½ (15) branched rays. Pectoral fin with 1 simple and 13 (5), 14 (6), 15 (28), 16 (29) and 17 (8) branched rays, outer margin slightly convex. Pelvic fin 1 simple and 8 (76) branched rays, outer margin convex. Caudal-fin deeply forked and lobes pointed. Axillary pelvic lobe present. Lateral line complete, reaching caudal-fin base, perforating 46-56 scales on body and 2 or 3 on caudal-fin base; 49 (1), 50 (4), 51 (9), 52 (12), 53 (10), 54 (8), 55 (10)–56 (9), 57 (9), 58 (3) and 59 (1) total lateral line scales. 9 (7), 10 (40) and 11 (29) scale rows lateral line and dorsal-fin origin; 4 (28), 5 (34) and 6 (14) scale rows lateral line and anal-fin origin. Ventral keel, slightly prominent, exposed for 3–10 scales in front of anus. 9 (1), 10 (9), 11 (9) and 12 (3) short gill rakers on first gill arch. Pharyngeal teeth 2.5–5.2 (5) or 2.5–5.1 (5). <b>Coloration.</b> Back and upper part of flank pale brown, lower part of flank and belly silvery in life. In formalin preserved fish, back and upper flank dark brown, lower part of flank and belly yellowish. A dark-brown or grey stripe present on upper part of flank from posterior margin of operculum to caudal peduncle, distinct on both anterior and posterior parts of flank, its width approximately equal to eye diameter. Scale pockets on back and flank above or slightly below lateral line dark-brown or grey. Dorsal and caudal fins grey; anal, pelvic and pectoral fins yellowish or hyaline. Small black dots on fin rays. <b>Distribution</b>. <i>Alburnus kotschyi</i> is known from Arsuz, Seyhan and Ceyhan Rivers flowing to the Mediterranean Sea in southern Turkey. <i>Alburnus</i> from Arsuz, Ceyhan and Seyhan could not be distinguished and also molecular data presented by Geiger <i>et al</i>. (2014) suggest that these populations are conspecific.
