Sequence Divergence. The mean of pairwise sequence divergences of COI gene based on K2P distance model within Group A, C, D, were 9, 12.8, and 9.9%,respectively, and the average distance among group was 14%.
The closest relationship within group was a pairwise between species Arctornis sp. 1 SEM 2008 and Arctornis sp. 2 SEM
2008 (1.6%).
The complete pairwise divergent of sequences within Arctornis is presented in Table 3.
