Trogiomorpha

thumb|Echmepteryx hamiltoni Lepidopsocidae are an insect family of bark lice belonging to the suborder Trogiomorpha. Colloquially, Lepidopsocidae are referred to as the Scaly-winged Barklice. There are more than 220 species described worldwide. Phylogenetic DNA analysis of relationships between families in Trogiomorpha propose that Lepidopsocidae is monophyletic, meaning that the taxa within all share a common ancestor. This is supported morphologically by the presence of scales and setae covering the body and forewings of Lepodopsocids. Sister families of Lepidoposcidae include Trogiidae and

Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea (formerly Psocoptera), alongside Troctomorpha and Psocomorpha. There are about eight families and more than 430 described species in Trogiomorpha. Trogiomorpha is widely agreed to be the earliest diverging of the three suborders, and retains the most primitive characteristics. thumb|Trogium pulsatorium

Prionoglarididae is a family of the order Psocodea (formerly Psocoptera) that are barklice characterized by the reduction or simplification of the lacinia in adults and the specialised form of the male genitalia. It contains the only known genus of animals, Neotrogla, where females possess a penis-like organ and take on typical male sex roles.
