In this study, we used the next-generation sequencing method to deduce two complete mitogenomes of King angelfish (Holacanthus passer) and Queen angelfish (Holacanthus ciliaris) for the first time. The assembled mitogenome consists of 16,620 bp in H. passer and 16,606 bp in H. ciliaris, showing 95% identities 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 903 bp in H. passer and 888 bp in H. ciliaris and locates between tRNA-Pro and tRNA-Phe. The overall GC content is 45.8% for H. passer and 46.2% for H. ciliaris. Complete mitogenomes of King angelfish and Queen angelfish deduced in this study provide essential and important DNA molecular data for further phylogenetic and evolutionary analysis for marine angelfish.
