| Abstract | Penguins are parasitised by 15 species of lice in the genera Austrogoniodes and Nesiotinus and present an opportunity to analyse phylogenetic relationships of two complete genera of chewing lice parasitising a monophyletic group of hosts. Taxonomy of penguin lice has been revised several times, including the erection of the genus Cesareus to contain some of the penguin-chewing louse species. Additionally, other groups of species within Austrogoniodes have been proposed. We constructed a phylogeny for all the chewing lice parasitising penguins from 46 parsimony-informative morphological characters and found support for two groups within Austrogoniodes, but little support for the Cesareus genus. Austrogoniodes metoecus, the only Austrogoniodes species parasitising a bird other than a penguin, was basal in the phylogeny, which suggests that if A. metoecus did originate from a louse species parasitising penguins, the host-switching event was unlikely to have been recent.
