Bayesian phylogenetic tree inferred from the nucleotide sequences of five mitochondrial protein-coding genes (cob, cox1, cox2, cox3, nad4) of 21 species of sucking lice (Anoplura). The elephant louse, Haematomyzus elephantis, was used as the outgroup. Bayesian posterior probability (Bpp) values were indicated near nodes followed by bootstrap support values (in brackets) from maximum likelihood (ML) tree (Supplementary Fig. 8)
