| Abstract | A phylogenetic analysis of generic relationships for avian chewing lice of the families Goniodidae and Heptapsogasteridae (Phthiraptera: Ischnocera) is presented. These lice, hosted by galliform, columbiform and tinamiform birds are reputedly basal in the phylogeny of Ischnocera. A cladistic analysis of sixty-two adult morphological characters from thirty-one taxa revealed thirty equally parsimonious trees. The phylogeny is well resolved within the Heptapsogasteridae and supports the monophyly of the subfamily Strongylocotinae (sensu Eichler, 1963). Resolution within the Goniodidae is lower but suggests that the genera hosted by Columbiformes are largely monophyletic. Mapping host taxonomy on to the phylogeny of the lice reveals a consistent pattern which is largely congruent down to the rank of host family, although at lower taxonomic levels the association appears to be more complex. The inclusion of more louse taxa may considerably help to unravel the coevolutionary history of both the hosts and their parasites. |
