Alburnoides coadi is distinguished from other congeners in Iran by a combination of the following characters: eye relatively small size, the orbit diameter larger than the snout length and markedly smaller than the interorbital width; caudal fin lobes rounded and fin moderately forked; a variably scaled ventral keel though most commonly scaled along about 2/3 of its length, or a completely scaled ventral keel; deep head with a markedly rounded and stout snout; small mouth which is between terminal and subterminal; a tip of the mouth cleft on a level from the lower margin of the pupil or somewhat below it; the lack of well-marked spots or dark pigmentation in the lateral line canal; 47-52 lateral line scales to posterior margin of hypurals; typically 9 or 10 scale rows between lateral line and dorsal fin origin; usually 5 or 6 scale rows between lateral line and anal fin origin; 2.5-4.2 pharyngeal teeth; commonly 17-19 scales around caudal peduncle; typically 39-41, with a mode of 40, total vertebrae; 13-14 predorsal vertebrae, 19-20 abdominal vertebrae, 19-21 caudal vertebrae; caudal vertebral region equal or slightly longer than an abdominal region (vertebral formulae 19 + 20, 20 + 20 and 20 + 21); usually 8½ branched rays on dorsal fin; commonly 12½-13½ branched rays on anal fin; usually 8 or 9 gill rakers in the outer row on first left arch (Ref. 106248).
