Oxynoemacheilus isauricus, new species, from the Lakes Beyşehir and Suğla basins in Central Anatolia is distinguished from all other species of the O. angorae group by having a very slender caudal peduncle (its depth 2.22.6 times in its length). The new species is further distinguished by having a short head (head length 2124% SL), and a midlateral series of irregularly shaped blotches on the flank. Oxynoemacheilus isauricus is also distinguished by a minimum K2P sequence divergence of 7.5% and 8.0% in the mtDNA-COI barcode region from O. eregliensis and O. atili, its closest relatives.
安纳托利亚中部贝希吉尔湖和苏格拉盆地的新种安纳托利亚半须𬶐区别于安纳托利亚半须𬶐属的其他所有种，其尾柄非常细长（深度为长度的 2.22.6 倍）。该新种还具有短的头部（头长占标准体长的 2124%）和体侧中部的一系列不规则形状的斑纹。安纳托利亚半须𬶐还通过 mtDNA-COI 条码区最小 K2P 序列差异与最接近的亲缘种埃雷利半须𬶐和阿特利半须𬶐分别达到 7.5%和 8.0%而得以区分。
