Herein, the complete mitochondrial genome of Odontobutis haifengensis was sequenced for the first time. The 0. haifengensis mitogenome was 17,016 bp in length and included 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region (CR). The genome organization, base composition, codon usage, and gene rearrangement was similar to other Odontobutis species. Furthermore, a tRNA gene rearrangement within the SLH cluster was found to be identical to other Odontobutis species. Moreover, the gene order and the positions of additional intergenic non-coding regions suggests that the observed unique gene rearrangement resulted from a tandem duplication and random loss of large-scale gene regions. Additionally, phylogenetic analysis showed that Odontobutis species form a monophyletic Glade due to the conserved mitochondrial gene rearrangement. This study provides useful information that aids in a better understanding of mitogenomic diversity and evolutionary patterns of Odontobutidae species.
