Members of Candidia, Nipponcrysis, Parazacco, Opsariichthys, and Zacco are a group of East Asian freshwater fishes, and these five genera form a monophyletic group within the subfamily Oxygastrinae (Cypriniformes: Cyprinidae). In this study, we first determined complete mitogenomes of Candidia pingtungensis, Opsariichthys acutipinnis, O. chengtui, and Zacco acanthogenys. The four mitogenomes with the length of 16 611-16 615 bp displayed the same patterns in gene arrangements and the use of start and stop codons for protein-coding genes. Our phylogeny divided Candidia, Nipponcrysis, Parazacco, Opsariichthys, and Zacco into two major groups that the former three genera consisted of a group and the latter two genera formed another group. The phylogeny also revealed that C. pingtungensis was nested within Nipponcrysis. Our findings indicate that the taxonomy status of Candidia and Nipponcrysis is still needed to be confirmed.
坎氏鱼属、日本刺皱属、副细鲫属、马口鱼属和细鲫属的成员是东亚淡水鱼的一个类群，这五个属在雅罗鱼亚科（鲤形目：鲤科）内形成一个单系类群。在本研究中，我们首次测定了屏东坎氏鱼、尖鳍马口鱼、陈氏马口鱼和棘鳍细鲫的完整线粒体基因组。这四个长度为16611 - 16615 bp的线粒体基因组在基因排列以及蛋白质编码基因起始和终止密码子的使用上呈现出相同模式。我们的系统发育分析将坎氏鱼属、日本刺皱属、副细鲫属、马口鱼属和细鲫属分为两个主要类群，前三个属组成一个类群，后两个属形成另一个类群。系统发育分析还表明屏东坎氏鱼嵌套在日本刺皱属内。我们的研究结果表明，坎氏鱼属和日本刺皱属的分类地位仍需进一步确认。
