Phylogenetic tree based on cytochrome c oxidase subunit 1 (cox1) gene sequences from 85 onchocercid specimens. The total length of the alignment is 474 bp. Filaria latala was included as the outgroup. The topology was inferred using Maximum Likelihood. Nodes are associated with bootstrap values based on 1000 replicates. Bootstrap support values < 70 are not shown. The scale-bar indicates the number of nucleotide substitutions. Reference specimens are in bold
