Psocomorpha is a suborder of barklice, booklice, and parasitic lice in the order Psocodea. There are more than 20 families and 5,300 described species in Psocomorpha.
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.
Amphipsocidae is a family of hairy-winged barklice in the order Psocodea. Most species are 3.0-4.5 mm long and have many setae (hairs) on the veins and margin of the forewing. The main veins of the forewing are usually lined with two rows of setae. Like the other members of the infra-order Caeciliusetae, they have a broad, flat labrum, with well defined edges.
Philotarsidae is a family of Psocodea belonging to the suborder Psocomorpha. The family is closely related to the family Pseudocaeciliidae, both within the infraorder Philotarsetae.
Myopsocidae is a family of mouse-like barklice, belonging to the infraorder Psocetae of the order Psocodea. This family is closely related to Psocidae, with which it shares similar wing-venation, but from which it is distinguished by three-segmented tarsi.
Pachytroctidae is a family of thick barklice in the order Psocodea. There are about 15 genera and at least 90 described species in Pachytroctidae.
Peripsocidae is a family of Psocodea belonging to the suborder Psocomorpha. Members of the family are characterised by their absence of an areola postica in their wings. Many of the recently described genera are closely allied to Peripsocus. The family includes more than 300 species.
Lachesillidae is a family of Psocodea belonging to the suborder Psocomorpha. Members of the family are characterized by a rounded, free areola postica in their wings. Males have diverse sclerotized genitalic structures. The family includes more than 400 species, most of them in the genus Lachesilla.
Elipsocidae is a family of Psocodea belonging to the infraorder Homilopsocidea. Members of the family have a free areola postica. Many species are apterous. The family includes about 130 species in more than 30 genera.
Caeciliusidae is a family of Psocodea belonging to the suborder Psocomorpha. The family was once named Caeciliidae, but the latter name was changed because of homonymy with the amphibian family Caeciliidae. The subfamily Paracaeciliinae was formerly in Caeciliusidae, but it has been elevated to family rank, Paracaeciliidae.
Tapinella is a genus of thick barklice in the family Pachytroctidae. There are at least 40 described species in Tapinella.
Trichadenotecnum is a genus of insects in the order Psocoptera, the booklice, barklice, and bookflies. It is one of the largest genera, including over 200 described species.
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 Psoquillidae.
Ptyctini is a tribe of common barklice in the family Psocidae. There are about 6 genera and at least 20 described species in Ptyctini.
Psocinae is a subfamily of common barklice in the family Psocidae. There are about 11 genera and at least 40 described species in Psocinae.
Soa is a genus of scaly-winged barklice in the family Lepidopsocidae. There are about six described species in Soa.
Cerastipsocus is a genus of common barklice in the family Psocidae. There are more than 20 described species in Cerastipsocus.
Trogiidae is a family of granary booklice in the order Psocodea. There are about 11 genera and more than 50 described species in Trogiidae.
Philotarsus is a genus of loving barklice in the family Philotarsidae. There are about 18 described species in Philotarsus.
Cerobasis is a genus of granary booklice in the family Trogiidae. There are at least 30 described species in Cerobasis.
