In this study, we used the next-generation sequencing method to determine the complete mitogenome of Japanese swallow angelfish (Genicanthus semifasciatus) and Ornate angelfish (Genicanthus bellus) for the first time. The assembled mitogenome, 16,722 bp and 16,734 bp in length, shows 95% identity to each other. Both mitogenomes follow the typical vertebrate arrangement, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes and a non-coding control region of D-loop. D-loop contains length of 1013 bp in G. semifasciatus and 1030 bp in G. bellus, and is located between tRNA-Pro and tRNA-Phe. The overall GC content is 46.4% for G. semifasciatus and 46.6% for G. bellus. The complete mitogenome of Japanese swallow angelfish and Ornate angelfish determined in this study provides essential and important DNA molecular data for further phylogenetic and evolutionary analyses for marine angelfish.
