  Psocodea is an order of insects comprising approximately 11,000 species across three extant suborders: Trogiomorpha, Troctomorpha, and Psocomorpha. The group includes free-living barklice and booklice, as well as the parasitic lice (formerly Phthiraptera). Molecular and morphological evidence demonstrates that parasitic lice evolved from within the barklice lineage, rendering the former order 'Psocoptera' paraphyletic. Members range from 1–10 mm in length and occupy diverse habitats from forest canopies to stored products.
