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 16511-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(CladeⅠ)is basal to the Sisoridae family,forming a sister clade to the Glyptosternoids(CladeⅣ).The topological structures constructed in this study raised doubts over the traditional classification system.These results will help better understand the feature s of the P.hodgarti mitogenome and provide a reference for further phylogenetic research on Sisoridae species.
