Trogiomorpha is one of the three major suborders of barklice, booklice, and parasitic lice in the order Psocodea, alongside Troctomorpha and Psocomorpha. There are about 8 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.
Compsocidae is a family of Psocodea belonging to the suborder Troctomorpha. The family comprises two extant species in two genera, both found in Mesoamerica. Compsocus elegans is found in Mexico and Central America, while Electrentomopsis variegata is found in Mexico. The antennae of each species have 13 or 14 segments. Two extinct genera, Burmacompsocus and Paraelectrentomopsis are known from the Cenomanian aged Burmese amber of Myanmar and Albian aged Spanish amber.
Sphindidae is a family of beetles, in the suborder Polyphaga. They are also known as slime mold beetles due to their exclusive feeding on slime molds during adult and larval stages, other aspects of their life history are obscure. Palaeontological discoveries since 2015 have added to the geologic history of Sphindidae, including the discovery of Libanopsis, placed in the extinct subfamily Libanopsinae.
Prionoglarididae is a family of the order Psocodea 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.
Psyllipsocidae is a family of cave barklice in the order Psocodea. There are about 7 genera and more than 70 described species in Psyllipsocidae.

Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Echinocups is an extinct genus of Ommatine beetle. It was created in 2020 to house three species originally assigned to Notocupes, E. denticollis, E. neli and E. ohmkuhnlei The genus name refers to the sharp spikes present on the elytra. All three species are known from the Cenomanian aged Burmese amber of Myanmar.
Mimarachnidae is an extinct family of planthoppers known from the Cretaceous period. Their name is derived from spots on the wings of the first described genera, Mimarachne and Saltissus, being suggestive of spider mimicry, but these characters are not distinctive for the family as a whole. The family is characterised by "simplified venation and setigerous metatibial pecten and hind leg armature". as well as "rounded anterior margin of pronotum, double carination of pronotum and mesonotum"
Babinskaiidae is an extinct family of neuropterans known from the Cretaceous period. They are part of the superfamily Myrmeleontoidea. Their distinguishing characters include: "long filiform antennae, narrowly elongated wings, with features such as trichosors, and presectorial cross veins present in both wings, and absence of forewing oblique vein". They are considered transitional between Nymphidae and more derived myrmeleontodoids, such as antlions.
Manicapsocidae is a family of Psocodea. It contains 8 extant species in 4 genera, with most of the species being found in the Neotropics, with one species in the Afrotropics. The extinct family Electrentomidae has been suggested to be a synonym of this family, though this has been considered premature by other scholars in the absence of cladistic analysis. Confirmed fossil species of the family are nearly as numerous as living ones, extending back to the Mid-Cretaceous.
Empheriidae is an extinct family of Psocoptera in the suborder Trogiomorpha.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.

Lepidomma is an extinct genus of ommatid beetle. The genus was first described in 2019 for the species L. tianae. Lepidomma was synonymised with Clessidromma by Kirejtshuk, 2020. This synonymy was disputed by Li et al. (2021), who maintained Lepidomma as a separate genus from Clessidromma. Three additional species of Lepidomma were described in 2020 and 2022. All four species are known from the Cenomanian aged Burmese amber of Myanmar.
