The phylogeny of the species of Phlebotomus and Sergentomyia based on maximum-likelihood (ML); the tree was constructed based on a multiple sequence alignment (haplotypes) of the mitochondrial Cyt b gene. The tree with the highest log likelihood (-5765.5028) is shown. Only bootstrap values higher than 70 % in which the associated taxa clustered together are indicated next to the branches. When the number of common sites was < 100 or less than one fourth of the total number of sites, the maximum parsimony method was used; otherwise BIONJ method with MCL distance matrix was used. Distance represents the number of base substitutions per site. The analysis involved 25 nucleotide sequences. All ambiguous positions were removed for each sequence pair. The (Ts/Tv) rate is 1.3664 among 897 sites in the final dataset
