Genetic differentiation among samples and haplotype clade of Lutzomyia umbratilis.

FST, pair-wise genetic differentiation; K, average number of nucleotide differences between populations; Dxy, average number of nucleotide substitutions per site between populations; Da, number of net nucleotide substitutions per site between populations; Ss, number of shared polymorphisms between pairs of populations; Sf, number of fixed differences between pairs of populations. The geographic distance (in km) between localities is represented inside the parentheses.***P = 0.00000±0.0000, after the Bonferroni correction.
