Pseudophoxinus iconii, a new species, is described from Cihanbeyli (Lake Tuz Basin, Konya, Central Anatolia, Turkey). It differs from other Central Anatolian Pseudophoxinus species (P. anatolicus, P. battalgilae, P. crassus, P. hittitorum) by the following characters: absence of a keel between the pelvic fin and anus; mouth terminal (upper lip equal to or slightly longer than lower lip); caudal peduncle length 1.6-1.9 times its depth; lateral line complete, with 48-61 perforated scales; 53-63 + 2-3 scales in lateral series; 13-15 scale rows between lateral line and dorsal-fin origin; 5-7 scale rows between lateral line. Pseudophoxinus iconii is presently only known to inhabit Cihanbeyli and Golyazi canals. It disappeared from another locality due to excessive water abstraction and resulting aridity.
