This tree diagram shows the relationships between several groups of organisms.
The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

close boxIntroduction
Suborder Troctomorpha comprises 49 families of bark lice, book lice, and parasitic lice in the infraorders Amphientometae and Nanopsocetae.
Discussion of Phylogenetic Relationships
Molecular analysis supports to the placement of the parasitic lice (Phthiraptera) in suborder Troctomorpha, along with the bark lice and book lice families traditionally included in Troctomorpha. Phthiraptera is placed in infraorder Nanopsocetae (18S nDNA, Johnson et al. 2004). Molecular studies of bark lice (excluding Phthiraptera) support the monophyly of Troctomorpha and the infraorders Nanopsocetae and Amphientometae (18S rDNA, and 12S, 16S, COI rDNA, Johnson and Mockford 2003; 18S rDNA, histone3 nDNA, and 16S mtDNA Yoshizawa et al. 2006).
