The complete mitochondrial genomes of 76 species from 43 genera under Cyprinidae were collected to reassess the molecular phylogeny of Opsariichthyinae Liao et al. 2011. The mitogenomes of three species, , and , were newly sequenced. Phylogenetic trees were reconstructed based on 13 concatenated multiple protein-coding genes with two ribosomal RNA genes. The concatenated dataset provided a new perspective on systematics and relationships. Tree topologies show that a monophyletic group containing , , , , and should belong to the group. In addition, the present results also strongly support that and should be regarded as distinct genera within the group. , , , and form a monophyletic group within Xenocyprididae, distinct from the group. Furthermore, is nested with four species of , a genus of ex-Cultrinae in Xenocyprididae. In addition, two major types of distinct stripes - longitudinal and vertical - were observed among species of the group and were highly correlated with molecular phylogenetic relationships. Such types of vertical and longitudinal stripes presented in the group might have originated in an ancestor species, after which distinct vertical stripes might have been lost among these cyprinids but retained in the group.
收集了鲤科43个属76个物种的完整线粒体基因组，以重新评估廖等人（2011年）所定义的马口鱼亚科的分子系统发育。新测序了三种鱼（此处原文未给出具体物种名）的线粒体基因组。基于13个串联的多蛋白编码基因和两个核糖体RNA基因重建了系统发育树。串联数据集为系统分类学和物种关系提供了新视角。树形拓扑结构表明，一个包含（此处原文未给出具体物种名）的单系类群应属于（此处原文未给出具体类群名）类群。此外，目前的结果也有力支持（此处原文未给出具体物种名）和（此处原文未给出具体物种名）应被视为（此处原文未给出具体类群名）类群中的不同属。（此处原文未给出具体物种名）在鲴科内形成一个单系类群，与（此处原文未给出具体类群名）类群不同。此外，（此处原文未给出具体物种名）与鲴科中前 Culterinae 属的四个（此处原文未给出具体物种名）物种嵌套在一起。此外，在（此处原文未给出具体类群名）类群的物种中观察到两种主要类型的不同条纹——纵向条纹和垂直条纹——并且与分子系统发育关系高度相关。（此处原文未给出具体类群名）类群中呈现的这种垂直和纵向条纹类型可能起源于一个祖先物种，在此之后，这些鲤科鱼类中不同的垂直条纹可能已经消失，但在（此处原文未给出具体类群名）类群中得以保留。
