Abstract: | Background Sucking lice (Phthiraptera: Anoplura) are obligate, permanent ectoparasites of eutherian mammals, parasitizing members of
12 of the 29 recognized mammalian orders and approximately 20% of all mammalian species. These host specific, blood-sucking
insects are morphologically adapted for life on mammals: they are wingless, dorso-ventrally flattened, possess tibio-tarsal
claws for clinging to host hair, and have piercing mouthparts for feeding. Although there are more than 540 described species
of Anoplura and despite the potential economical and medical implications of sucking louse infestations, this study represents
the first attempt to examine higher-level anopluran relationships using molecular data. In this study, we use molecular data
to reconstruct the evolutionary history of 65 sucking louse taxa with phylogenetic analyses and compare the results to findings
based on morphological data. We also estimate divergence times among anopluran taxa and compare our results to host (mammal)
relationships. |
