Oxynoemacheilus fatsaensis, a new nemacheilid loach from the Elekçi Stream in Northern Anatolia (Teleostei: Nemacheilidae). Zoologischer Anzeiger, 294, 39–49. https://doi.org/10.1016/j.jcz.2021.07.0110044-5231https://doi.org/10.1016/j.jcz.2021.07.011https://hdl.handle.net/20.500.12428/6811We report a new species, Oxynoemacheilus fatsaensis, from the Elekçi 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.eninfo:eu-repo/semantics/closedAccessBiodiversityBlack seaFreshwater fishTaxonomyArticle294394910.1016/j.jcz.2021.07.011Q2WOS:0006970344000052-s2.0-85111303418
