Complete mitochondrial genome of Papilio syfanius (Lepidoptera: Papilionidae).

The complete mitochondrial genome (mitogenome) of the swallowtail butterfly Papilio syfanius has been completed. It is 15,359 bp, and contains the typical complement of 13 protein-coding (PCGs), 22 transfer RNA (tRNA) and 2 ribosomal RNA (rRNA) genes. Two A + T-rich regions are included in this mitogenome. The nucleotide composition is very similar to other insects, showing a high bias towards A + T, especially the control region (92.8%). Gene order in P. syfanius mitogenome is basically identical to that of the inferred ancestral insect genome, with the exception of translocations of trnM, which is common in genus Papilio.
