Abstract
Epicauta aptera Kaszab (E. aptera), an endangered species used to extract cantharidin in Chinese traditional medicine, has a limited geographical distribution in the southwest China. The complete mitochondrial genome of E. aptera is 15 645bp which contains an A + T rich region and 37 genes, including 13 protein-coding genes, 22 tRNA genes and two rRNA genes (GenBank accession No. KX023302). All protein-coding genes are initiated by ATN start codon. Moreover, the largest non-coding A + T-rich region with a length of 1039 bp is at the end of 12S rRNA. It is the first report involved in the complete mitochondrial genome of E. aptera.
