Barbus xanthos, new species, is described from the EŞen, Dalaman, Tersakan and Büyük Menderes River in southwestern Anatolia. It differs from other Barbus species in the adjacent basins by having 53-60 lateral line scales, a weakly ossified last unbranched dorsal-fin ray about 33%-50%, numerous small irregular shaped black or dark brown spots smaller than scales, often forming large, black or dark-brown blotches on back and flank in juvenile and adults, and the posterior dorsal-fin margin straight or slightly convex. Barbus xanthos differs from its most closely related congener, B. pergamonensis, by 9 nucleotide substitution sites in the mtDNA cytochrome oxidase I barcode region.

Barbus xanthos 是新物种，来自安纳托利亚西南部的 EŞen、Dalaman、Tersakan 和 Büyük Menderes 河。与邻近盆地的其他巴布亚种不同，侧线鳞片53-60片，最后不分枝的背鳍鳍条弱骨化约33%-50%，许多小不规则形状的黑色或深褐色小点小于鳞片，经常形成幼鱼和成鱼的背部和侧面有大的黑色或深棕色斑点，后背鳍边缘笔直或微凸。Barbus xanthos 与其最密切相关的同源物 B. pergamonensis 的不同之处在于 mtDNA 细胞色素氧化酶 I 条形码区域中的 9 个核苷酸取代位点。本文受版权保护。版权所有。
