Abstract
The mitochondrial genome of Erronea caurica from the South China Sea has been determined (GenBank Accession No. MT522622), which was the second report of mitochondrial genome in the superfamily Cypraeoidea. It is 16,053 bp long and consists of 21 tRNA genes, 2 rRNA genes, 13 protein-coding genes, and 1 control region. As previously reported mitochondrial genome in Cypraeoidea, all protein-coding genes of E. caurica use a typical start codon (ATN) and a complete stop codon (TAA or TAG). Phylogenetic tree demonstrated that E. caurica belongs to the family Cypraeoidea and closer to the superfamily Tonnoidea.
