Haplotype network derived from 175 haplotypes from 689 bp of the COI gene sequences from 326 specimens of the Anopheles triannulatus complex. A) Geographic distribution of the COI lineages; B) Haplotypes are represented by circles and their frequency is proportional to the area. Numbers represent mutational steps between haplotypes and grey dots are median vectors. The An. darlingi and An. nuneztovari outgroup sequences (black dots) joined the network at the Colombian haplotypes and they are septed from all the Anopheles triannulatus complex individuals by more than 50 fixed differences.
