摘要： The complete mitogenome of Parachiloglanis hodgarti was sequenced and characterized, which is the first mitogenome of the genus Parachiloglanis within Sisoridae. The mitogenome is 16 511-bp long and included 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs, and one control region. The genome composition was A+T biased (58.64%) and exhibited a positive AT-skew (0.095) and a negative GC-skew (-0.283). Compared with other Sisoridae fishes, the characteristics of nucleotide skews, codon usage, and amino acid usage of the P. hodgarti mitogenome are more similar to those of non-Glyptosternoid fishes. Furthermore, the phylogenetic trees show that Sisoridae fishes fall into four major clades and P. hodgarti (Clade I) is basal to the Sisoridae family, forming a sister clade to the Glyptosternoids (Clade IV). The topological structures constructed in this study raised doubts over the traditional classification system. These results will help better understand the features of the P. hodgarti mitogenome and provide a reference for further phylogenetic research on Sisoridae species.
