A novel clade of parasitic lice of eutherian mammals supported by shared derived characters in mitochondrial genome organization and phylogenetic analysis of mitochondrial genome sequences. In the upper broken-line box are the bird lice from the suborders Amblycera and Ischnocera and the wallaby louse from the Amblycera; these lice all have the typical single-chromosome mitochondrial genomes. In the lower broken-line box are the eutherian mammal lice from the suborders Ischnocera, Rhynchophthirina, and Anoplura; these lice all have fragmented mitochondrial genomes. Bird and mammal hosts are indicated after the names of parasitic lice. When only protein-coding and rRNA genes are considered, the eutherian mammal lice from the Ischnocera and the Rhynchophthirina and the most recent common ancestor of Anoplura have five minichromosomes in common. The phylogenetic tree was constructed with PCGRNA matrix (5677 bp in total) using PhyloBayes with the CAT+GTR model and IQTREE web server with the TIM+F+I+G4 model (see Materials and Methods for details). ML bootstrap values and Bayesian posterior probabilities for each grouping are indicated near the branch nodes.
