Molecular diversity indices for six species of endemic arthopods in each of the Azorean islands investigated, based on COI sequence data. N, number of individuals; h, number of haplotypes; hrar, rarefied number of haplotypes; Uh, number of unique haplotypes; Hd, haplotype diversity; π, nucleotide diversity; SD, standard deviation. For Tajima’s D and Fu’s FS * 0.01 < P < 0.05; ** 0.001 < P < 0.01 and *** P < 0.001 otherwise P > 0.05. The discordance between number of individuals (N) for COI between this table and Additional file 1: Table S1 is due to the fact that for this analysis individuals having shorter COI sequences were removed
