The complete mitochondrial genome of Leech (Lepidoptera: Papilionidae) from China.

The complete mitochondrial genome of that is endemic to China is determined. The circular genome is 15 550 bp in length and comprises 13 protein-coding genes (PCGs), 22 tRNAs, two rRNA gene and a control region. Gene order is identical to that of the putative ancestral arrangement of insects. The nucleotide composition of heavy strand is A (40.3%), C (11.2%), T (41.1%) and G (7.3%). All PCGs start with a typical ATN codon except for the gene COI that uses AAC as the start codon. Bayesian analyses support the monophyly of genus and the sister relationship of and .
