Fig 2. Onchocercid clades based on partitioned concatenated datasets of 12S rDNA, coxI, rbp1, hsp70, myoHC, 18S rDNA, and 28S rDNA sequences using Bayesian Inference.

The total length of datasets is approximately 4950 bp. Sixty onchocercid specimens (representing 48 species) were analysed. Filaria latala and Protospirura muricola were used as outgroups. Bayesian posterior probabilities support five clades named ONC1 to ONC5. Dotted areas represented species of the same genus. The topology was inferred using Bayesian (B) inference on one run of 5 million generations. The onchocercid subfamilies are indicated by colour: blue for Onchocercinae, dark green for Dirofilariinae, purple for Splendidofilariinae, pale green for Setariinae, yellow for Waltonellinae, orange for Icosiellinae and red for Oswaldofilariinae.
