The complete mitochondrial genome of Xyrias revulsus（Jordan & Snyder, 1901）.

Xyrias revulsus is one of the species in the China-Vietnam Collective Fishery Zone, which has a few relevant studies. In this study, the mitochondrial genome of X. revulsus was determined for the first time using next-generation sequencing; the overall base components of mitogenome consisting of 17,784 bp was 32.45% for A, 25.76% for T, 15.72% for G, 26.08% for C, and its GC content was 41.8%. The mitochondrial circular genome was composed of 13 protein-coding genes, 22 transfer RNAs, 2D-loop, and 2 ribosomal RNAs. Polygenetic analysis showed that the X. revulsus was very close to Ophisurus macrorhynchos. It can provide data reference for the analysis of genetic evolution of this species.
