Sinocyclocheilus anshuiensis is a special cavefish that lives in the Southwestern China with many specific regressive features, such as rudimentary eyes and scales, and loss of pigmentation. In this study, we performed sequencing and assembly of its complete mitochondrial genome. We confirmed that total length of the mitochondrion is 16 618 bp with an AT ratio of 55.4%. The complete mitochondrial genome contains 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs and a 963 bp control region. Our current data provide important resources for the research of cavefish mitochondrial evolution and energy metabolism.
