Neighbour joining phylogenetic tree (based on Kimura 2-parameter genetic distance model) of COI sequences of all 79 haplotypes of anopheline species collected from Sri Lanka during the study (red label) and the sequences retrieved from the GenBank (black label). Armigeres subalbatus and Culex tritaeniorhynchus were used as the out-groups. Only node support greater than 90% is shown. The study site/s from which each haplotype was collected are given in parentheses (Ampa Ampara, Badu Badulla, Batt Batticoloa, Jaff Jaffna, Kuru Kurunegala, Mann Mannar, Mata Matale, NE Nuwara-Eliya)
