a N, number of individuals (mtDNA)/chromossomes (nucDNA). Polymorphism indexes: H, number of haplotypes detected; S, number of segregating sites; Hd, haplotype diversity; π, nucleotide diversity; θw, population mutation parameter [62]. Neutrality test: D, Tajima’s D. Population growth tests: FS, Fu’s FS; R2, Ramos-Onsins and Rozas’ R2.* p < 0.05; ** p < 0.01.

b Statistics were not computed for P. astriata population from Fregate as only three individuals were sampled. Populations from outer islands and hypothetically introduced individuals (3, see above) were also excluded of calculations.
