  1. Genetic diversity measures for 14 local populations used for COI sequences analysis: Samples size (N), number of segregating sites (S), number of haplotypes (H), haplotype richness after rarefaction (Rh), nucleotide diversity (π), average number of nucleotide differences between pairs of sequences (k). Demographic inference analyses: neutrality tests [Tajima’s D (D) and Fu & Li’s F (F)] (significant values are in bold), probability values associated with Sum of Squares Deviation of the mismatch frequency distribution of the number of pairwise nucleotide differences [P (SSD)] and probabilities of Harpending’s Raggedness index [P (Hr)]. Both SDD and Hr were calculated based on expected mismatch distribution according to the demographic (Demo. expansion) and geographic expansion (Geo. expansion) models
