Phylogenomics reveals the timescale of diversification in Amblycera
Next‐generation sequencing changes the higher taxonomy of Amblycera (Insecta: Phthiraptera). Families Trimenoponidae and Gyropidae merge into Gyropidae; Trinotonidae is a separate family; several genera are paraphyletic. The ancestral host of Amblycera was likely a bird; Amblycera switched to mammals twice.

On the origin of Halipeurus heraldicus on Round Island petrels: cophylogenetic relationships between petrels and their chewing lice [PDF]
Lice phylogenetic relationships have often been used to elucidate host relationships and vice versa. In this study, we investigate the louse genus Halipeurus which parasitizes bird hosts in the families Procellariidae, Hydrobatidae and Pelecanoididae ...

African savanna elephant lice and Asian elephant lice differ by ~17% in cox1 gene sequence and by >23% in combined sequences of 23 mitochondrial genes. Mitochondrial gene sequence divergences between African and Asian elephant lice are 3.76–4.6 times higher than that between their hosts.
