Abstract

We report a new species, Oxynoemacheilus fatsaensis, from the Elekci Stream, a small stream that flows to the Black Sea in Northern Turkey. It is distinguished from other Oxynoemacheilus species in the Black Sea, Upper Euphrates, and Kura-Aras River basins by having a suborbital groove in males, an axillary lobe at the pelvic-fin base, no dorsal adipose crest on the caudal peduncle, a deeply emarginate caudal fin, small inner and outer rostral barbels, and mottled flank pattern. Molecular data suggest that the new species is separated by a minimum p-distance of 3.3% from O. banarescui in the mitochondrial DNA COI barcode region. (c) 2021 Published by Elsevier GmbH.
