Phylogeny of COI sequences based on maximum likelihood approach. Tree with the highest likelihood score (Final ML Optimization Likelihood Optimization: − 1753.729080) is shown. Anopheles stephensi sequences are shown in color, indicating location of capture, with red indicating taxa in Lawyacado, orange indicating taxa in Berbera and pink indicating taxa in Hargeisa. For An. gambiae sensu lato, blue indicates Hargeisa. Bootstrap values > 70 for notable species clades are shown at nodes. Nodes without numbers had a value < 70. Anopheles stephensi COI haplotypes found in Somaliland (Hap 2–4) are identified with brackets. Abbreviations: COI, Mitochondrial cytochrome oxidase subunit I locus; Hap, haplotype; ML, maximum likelihood
