Figure 2. Phylogenetic trees (ML) of six Dendrolimus pine moth species constructed with single COI gene and Haplotype network for three mostly closely related species D. punctatus, D. tabulaeformis, D. spectabilis A) ML tree based on COI gene; Clades with different colors indicate different species respectively.

MW - D. punctatus, SM - D. kikuchii, YN - D. houi, YS - D. tabulaeformis, CS - D. spectabilis, LY - D. superans; OG - OUTGROUP; Numbers above branches indicate bootstrap values (less than 50 not shown) (hereinafter). Clades with light blue branches indicate GMYC species, see text for details; B) Haplotype network based on COI gene. Empty circles mean haplotypes of species D. punctatus, gray circles indicate haplotypes of species D. tabulaeformis, and black circles represent haplotypes of species D. spectabilis. Shared haplotypes between different individuals from the same species or different species were listed in Appendix S4, hereinafter.
