Table 2 Geographic information, nucleotide polymorphism and neutrality tests of 85 populations. S, number of segregating sites; Hap, haplotype distribution; Hd, haplotype diversity; π, nucleotide diversity; The number after the population name represents the groups divided by genetic marker COI which it belongs to, 1 represents it belongs to NE group. 2 and 3 represents SN group and SE group, respectively. The bold black font represents the groups divided by zoogeographic regions.
