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.
Troctomorpha is one of the three major suborders of Psocodea (barklice, booklice, and parasitic lice), alongside Psocomorpha and Trogiomorpha. There are more than 30 families and 5,800 described species in Troctomorpha. The order includes parasitic lice, which are most closely related to the booklice family Liposcelididae.
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.
Liposcelididae is a family of booklice of the order Psocodea, belonging to the suborder Troctomorpha. Members of this family are small and flattened, and often wingless. Mesothorax and metathorax fused in wingless forms.
Pachytroctidae is a family of thick barklice in the order Psocodea. There are about 15 genera and at least 90 described species in Pachytroctidae.
Sphaeropsocidae is a family of Psocodea, belonging to the suborder Troctomorpha. Females of this family have reduced, beetle-like elytra, and lack hindwings, with males have either small or absent wings. The family comprises 22 known species in eight genera.
The Berothidae are a family of winged insects of the order Neuroptera. They are known commonly as the beaded lacewings. The family was first named by Anton Handlirsch in 1906. The family consists of 24 genera and 110 living species distributed discontinuously worldwide, mostly in tropical and subtropical regions. Numerous extinct species have also been described. Their ecology is poorly known, but in the species where larval stages have been documented, the larvae are predators of termites.
Neotrogla is a genus of barklice noted for its reversed sex roles and organs, traits shared by all species of the genus.
Psyllipsocidae is a family of cave barklice in the order Psocodea. There are about 7 genera and more than 70 described species in Psyllipsocidae.
Trogiidae is a family of granary booklice in the order Psocodea. There are about 11 genera and more than 50 described species in Trogiidae.
Electrentomidae is an extinct family of barklice, booklice, and parasitic lice in the order Psocodea. There are about six genera and seven described species in Electrentomidae. The family was synonymsed with the extant family Manicapsocidae in 2003 without discussion, with a prior proposal in 1972, but Azar et al., 2017, stated that "we consider herein [Electrentomidae and Manicapsocidae] apart, because a cladistic phylogenetic analysis is needed prior to taking such important decision for these groups."

2020 in paleoentomology is a list of new fossil insect taxa that were described during the year 2020, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
2015 in paleoentomology is a list of new fossil insect taxa that were described during the year 2016, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
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.
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.
This paleoentomology list records new fossil insect taxa that were to be described during the year 2021, as well as notes other significant paleoentomology discoveries and events which occurred during that year.
Cormopsocidae is an extinct family of Psocodea. All currently known members are from the mid-Cretaceous Burmese amber of Myanmar. The family is considered either to be the earliest diverging group of the suborder Trogiomorpha, or the sister group to all other psocids, and retains many primitive characteristics.
This paleoentomology list records new fossil insect taxa that are to be described during the year 2022, as well as notes other significant paleoentomology discoveries and events which occurred during that year.
Palaeosiamoglaris is a genus of fossil psocids in the family Prionoglarididae, found in mesozoic amber.
