Oxynoemacheilus hazarensis, new species, from Lake Hazar in the Turkish Tigris drainage, is distinguished from other Oxynoemacheilus in the Tigris drainage by having the combination of a slightly emarginate caudal fin, no suborbital groove in males, an incomplete lateral line, no scales on the back and flank in front of the anus, the maxillary barbel reaching beyond the middle of the eye, an incision in the middle of the upper lip, and the colour pattern on the flank mottled, not interrupted by an unpigmented zone along the lateral line. Oxynoemacheilus euphraticus from the Euphrates and Tigris drainages is a valid species: it is discussed and re-diagnosed against O. argyrogramma.
来自土耳其底格里斯河水系哈扎尔湖的新物种哈扎尔高原鳅(Oxynoemacheilus hazarensis),与底格里斯河水系的其他高原鳅属物种不同,其特征在于尾鳍略呈凹形、雄性无眶下沟、侧线不完全、肛门前方的背部和侧面无鳞片、上颌须超过眼中部、上唇中部有切口,以及侧面的颜色图案呈斑驳状,不被沿侧线的无色素区域中断。来自幼发拉底河和底格里斯河水系的银斑高原鳅(Oxynoemacheilus euphraticus)是一个有效物种:本文针对银纹高原鳅(O. argyrogramma)对其进行了讨论和重新诊断。
