A new Pseudophoxinus (Teleostei, Cyprinidae) species from Asi River Drainage (Turkey)

Abstract

Pseudophoxinus turani sp. n. is described from the İncesu Spring (Hassa-Hatay) drainage of Asi River, Turkey. It is distinguished from other Eastern Mediterranean Region Pseudophoxinus species by a combination of characters: lateral line incomplete, with 12-25 (commonly 16-21) perforated scales and 38-46+2-3 scales in lateral series (commonly 41-44 +2-3); 10-11 scale rows between the lateral line and dorsal-fin origin; 3-4 scale rows between the lateral line and the pelvic-fin origin; dorsal fin with 71/2 branched rays; anal fin commonly with 71/2 branched rays; 8-11gill rakers on the first branchial arch; dorsal profile markedly convex with marked hump at the nape, ventral profile less convex than dorsal profile; a small, irregular, black blotch on the base of the caudal fin; mouth terminal, with slightly distinct chin, its corner not reaching vertical through anterior margin of eye; snout somewhat long, with rounded tip; and its length greater than eye diameter.
