Phylogeny of onchocercid filarioids constructed using maximum-likelihood (ML) estimations based on concatenated MyoHC, hsp70, rbp1, 12S rRNA, 28S rRNA, 18S rRNA, and cox1 nucleotide sequences with a total of 2,935 unambiguously aligned bp (best-fit approximation for the evolutionary model: GTR+G+I). Major genera of the Dipetalonema lineage (Acanthocheilonema, Yatesia, Cercopithifilaria, Cruorifilaria, Monanema, Litomosoides, and Dipetalonema), including representative species with indication of vector range (ticks, biting midges, parasitic mites), are indicated. Numbers at nodes indicate percentage support of 1,000 bootstrap replicates. Only bootstrap values >70% are shown. The scale bar is in units of substitution/site.
