The Garra species inhabiting the Hajar Mountains are revised and five species are recognised, two of which are newly species described herein. Garra barreimiae, from the United Arab Emirates (UAE) and Northern Oman, is distinguished from other Garra species in the Hajar Mountains by a strongly mottled flank pattern with individual or series of midlateral orange scales, a white dorsal-fin tip, an orange spot at the upper operculum, and more gill rakers on the lower limb of the first gill arch. Garra barreimiae shawkahensis is a synonym of G. barreimiae. Garra gallagheri, from the Wadi Bani Khalid drainage in Oman, is distinguished by flank-scale margins the same colour or slightly darker than the centre of the scales. Garra longipinnis, from the interior wadis in the Central Hajar Mountains in Oman, is distinguished by flank-scale margins being clearly darker than the centre of scales. The original description of G. longipinnis was based on a few individuals with very large fins, which are here considered aberrant. Garra shamal, new species, from the coastal drainages around Muscat in Oman, is distinguished by a strongly mottled flank pattern usually without orange midlateral scales, a white dorsal-fin tip, no orange spot at the upper operculum, and middle caudal-fin rays and membranes the same colour or slightly darker than the rest of the fins in colouration. Garra sharq, new species, from the Wadi Kabbah drainage and a few interior springs in Oman, is distinguished by a strongly mottled flank pattern with individual or series of orange midlateral scales, no orange spot at the upper opercle, and dorsal-fin tip and membranes between central caudal-fin rays the same colour as the rest of the fins. All five species are well differentiated genetically and form distinct mitochondrial clades with between 2.1 and 9.2% differences (p-distances) in the mitochondrial COI.
对栖息在哈杰尔山脉的裂腹鱼属物种进行了修订，确认了5个物种，其中2个是本文描述的新物种。来自阿拉伯联合酋长国（阿联酋）和阿曼北部的巴林裂腹鱼，与哈杰尔山脉的其他裂腹鱼物种不同，其侧腹斑纹强烈，有单个或一系列体侧中部橙色鳞片，背鳍尖端白色，鳃盖上部有橙色斑点，第一鳃弓下支的鳃耙更多。巴林裂腹鱼肖卡亨西斯是巴林裂腹鱼的同义词。来自阿曼瓦迪巴尼哈利德排水系统的加拉格尔裂腹鱼，其特征是侧腹鳞片边缘颜色与鳞片中心相同或略深。来自阿曼哈杰尔山脉中部内陆河谷的长鳍裂腹鱼，其特征是侧腹鳞片边缘明显比鳞片中心颜色深。长鳍裂腹鱼的原始描述基于少数鳍非常大的个体，这里认为这些个体是异常的。来自阿曼马斯喀特周边沿海排水系统的新物种沙马尔裂腹鱼，其特征是侧腹斑纹强烈，但通常没有体侧中部橙色鳞片，背鳍尖端白色，鳃盖上部没有橙色斑点，尾鳍中部鳍条和鳍膜颜色与其他鳍相同或略深。来自阿曼瓦迪卡巴赫排水系统和一些内陆泉水的新物种东部裂腹鱼，其特征是侧腹斑纹强烈，有单个或一系列体侧中部橙色鳞片，鳃盖上部没有橙色斑点，背鳍尖端和中央尾鳍鳍条之间的鳍膜颜色与其他鳍相同。所有这5个物种在基因上都有很好的区分，形成了不同的线粒体分支，线粒体细胞色素氧化酶亚基I（COI）的差异（p距离）在2.1%至9.2%之间。
