The complete mitochondrial genome (mitogenome) sequences of Papilio nephelus chaon and Papilio epycides were sequenced by Illumina and analyzed in this study. They are 15,287 bp and 15,012 bp in size, respectively, and contains 13 protein-coding genes (PCGs), 22 tRNA genes (tRNAs), 2 rRNA genes (rRNAs), and 1 AT-rich control region (CR). The phylogenetic relationships of 56 species in the Papilionidae were inferred based on concatenated nucleotide sequences by using Maximum Likelihood with the selected best-fit model GTR + F+R6. The phylogenetic analysis showed that P. nephelus chaon and P. epycides were located in the genus Papilio. This study provides a basis for further study on mitogenome and phylogenetics of the Papilionidae.
