Fig. 2

The haplotype network of the cytochrome c oxidase subunit I (COI) gene was constructed using Network 10.2. Each circle represents a haplotype and its size is proportional to the number of individuals included in the haplotype. Pink, green, and blue represent individuals from Baekyeon-ri (BY), Josan-ri (JS), and Yanggu (YG), respectively. White dots (median vectors) represent undetected hypothetical haplotypes. Black circles indicate haplotypes with the same sequence as the reference (H_101: OP311323, Heilongjiang, China; H_105: KC855655, Khabarovsk, Russia)
