The taxonomy of the order Phthiraptera is unstable and still problematic to researchers. Most of the current taxon classifications are mainly based on morphological features. Campanulotes bidentatus belongs to the chewing lice of the Philopteridae family that mostly parasitic on birds. There is a lack of sequence data and phylogenetic analyses on the family Philopteridae. In the current study, C. bidentatus was collected from the domestic pigeon Columba livia and identified morphologically and molecularly based on the mitochondrial cytochrome c oxidase subunit 1 gene (COI). The infection rate of the Campanulotes genus was approximately 58.82% in this study. Phylogenetic analysis based on the mt COI gene was informative for members of Philopteridae and the group taxon genera formed distinct clades. Future studies were recommended using the 16s rRNA to enhance the tree topology and obtain clear differentiation between genera.

拟杆菌属的分类学是不稳定的，对研究者仍然是有问题的。当前的大多数分类单元分类主要基于形态特征。桔梗（Campanulotes bidentatus）属于费城科（Philopteridae）的咀嚼虱子，其主要寄生于鸟类。Phil科（Philopteridae）缺乏序列数据和系统发育分析。在当前的研究中，C。bidentatus是从家鸽“哥伦布”中提取的，并基于线粒体细胞色素C氧化酶亚基1基因（COI）进行了形态和分子鉴定。风铃草的感染率在该研究中属约58.82％。基于mt COI基因的系统发育分析为Phil科成员提供了有益的信息，而群体分类群形成了不同的进化枝。建议使用16s rRNA进行进一步的研究，以增强树的拓扑结构并获得属之间的明确区分。
