The freshwater fish family Botiidae is represented by seven genera on the Indian subcontinent and in East and Southeast Asia and includes diploid as well as evolutionary tetraploid species. We present a phylogeny of Botiidae including 33 species representing all described genera using the mitochondrial cytochrome b and 12s rRNA genes to reconstruct the phylogenetic relationships among the genera and to estimate the number of polyploidisation events during their evolution. Our results show two major lineages, the subfamilies Leptobotiinae with the genera Leptobotia and Parabotia and Botiinae with the genera Botia, Chromobotia, Sinibotia, Syncrossus, and Yasuhikotakia. Our results suggest that two species that were traditionally placed into the genus Yasuhikotakia form a monophyletic lineage with the species of Sinibotia. A review of the data on the ploidy level of the included species shows all diploid species to belong to Leptobotiinae and all tetraploid species to Botiinae. A single polyploidisation event can therefore be hypothesised to have occurred in the ancestral lineage leading to the Botiinae.
淡水鱼科野鲮科在印度次大陆以及东亚和东南亚地区有七个属，包括二倍体物种以及进化而来的四倍体物种。我们利用线粒体细胞色素b和12s rRNA基因，构建了包含代表所有已描述属的33个物种的野鲮科系统发育树，以重建各属之间的系统发育关系，并估计它们在进化过程中的多倍体化事件数量。我们的结果显示出两个主要谱系，即包含野鲮属和拟野鲮属的野鲮亚科，以及包含粒鲮属、中华粒鲮属、华缨鱼属、异斑属和泰波鱼属的野鲮亚科。我们的结果表明，传统上归入泰波鱼属的两个物种与中华粒鲮属的物种形成一个单系谱系。对所包含物种倍性水平数据的回顾表明，所有二倍体物种都属于野鲮亚科，所有四倍体物种都属于野鲮亚科。因此，可以假设在导致野鲮亚科的祖先谱系中发生了一次多倍体化事件。
