In this study, we cloned and sequenced the complete mitochondrial genome of Odontobutis potamophila. The genome was found to be 16,932 bp in size with a mostly conserved structural organization when compared with that of other teleost fish. It contained 37 genes (13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes) and 2 main non-coding regions (the control region and the origin of the light strand replication). Rearrangements of tRNAs (tRNA-Ser, tRNA-Leu, tRNA-His) and three additional longer non-coding regions (43 bp, 336 bp and 76 bp, respectively) were present between the ND4 and ND5 genes. Within the control region, typical conserved domains, such as the termination-associated sequence, central and conserved sequence blocks domains were identified. This mitogenome sequence data would contribute to better understanding population genetics and phylogenetic analysis of the Odontobutidae.
