Garra imberba is widely distributed in China. At the moment, both Garra yiliangensis and G. hainanensis are treated as valid species, but they were initially named as a subspecies of G. pingi, a junior synonym of G. imberba. Garra alticorpora and G. nujiangensis also have similar morphological characters to G. imberba, but the taxonomic statuses and phylogenetic relationships of these species with G. imberba remains uncertain. In this study, 128 samples from the Jinshajiang, Red, Nanpanjiang, Lancangjiang, Nujiang Rivers as well as Hainan Island were measured while 1 mitochondrial gene and 1 nuclear intron of 24 samples were sequenced to explore the phylogenetic relationship of these five species. The results showed that G. hainanensis, G. yiliangensis, G. alticorpora and G. imberba are the same species with G. imberba being the valid species name, while G. nujiangensis is a valid species in and of itself.
云南墨头鱼在中国分布广泛。目前，异吻墨头鱼和海南墨头鱼都被视为有效物种，但它们最初被命名为平鳍墨头鱼的一个亚种，而平鳍墨头鱼是云南墨头鱼的次异名。高体墨头鱼和怒江墨头鱼也具有与云南墨头鱼相似的形态特征，但这些物种与云南墨头鱼的分类地位和系统发育关系仍不确定。在本研究中，测量了来自金沙江、红河、南盘江、澜沧江、怒江以及海南岛的128个样本，并对24个样本的1个线粒体基因和1个核内含子进行了测序，以探讨这五个物种的系统发育关系。结果表明，海南墨头鱼、异吻墨头鱼、高体墨头鱼与云南墨头鱼为同一物种，云南墨头鱼为有效物种名，而怒江墨头鱼本身就是一个有效物种。
