Phylogenetic analysis of Gigantodax (Diptera: Simuliidae)
Abstract A study of the monophyly and phylogenetic relationships among the Gigantodax species-groups was conducted using all Gigantodax species and six outgroups. This analysis was conducted using 71 characters, 58 of them morphological characters derived from 66 species, and 13 of them cytological...

The remaining four groups (“brophyi”, “cilicinus”, “minor”, and “wrighti”) are non-monophyletic.
