Linognathidae is a family of lice in the order Psocodea. There are at least 3 genera and 70 described species in Linognathidae. [1] [2] [3] [4]
These three genera belong to the family Linognathidae:
Sucking lice have around 500 species and represent the smaller of the two traditional superfamilies of lice. As opposed to the paraphyletic chewing lice, which are now divided among three suborders, the sucking lice are monophyletic.
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 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.
Pachytroctidae is a family of thick barklice in the order Psocodea. There are about 15 genera and at least 90 described species in Pachytroctidae.
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.
Psyllipsocidae is a family of cave barklice in the order Psocodea. There are about 7 genera and more than 70 described species in Psyllipsocidae.
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.
Psoquillidae is a family of bird nest barklice in the order Psocodea. There are about 8 genera and more than 30 described species in Psoquillidae.
Trogiidae is a family of granary booklice in the order Psocodea. There are about 11 genera and more than 50 described species in Trogiidae.
Boopiidae is a family of lice in the order Psocodea. There are about 8 genera and more than 50 described species in Boopiidae.
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."
Enderleinellidae is a family of parasitic lice in the order Psocodea. There are about 5 genera and more than 50 described species in Enderleinellidae.
Gyropidae is a family of lice in the order Psocodea. There are about 9 genera and more than 90 described species in Gyropidae.
Hoplopleuridae is a family of lice in the order Psocodea. There are about 6 genera and more than 150 described species in Hoplopleuridae.
Paracaeciliidae is a family of bark lice in the order Psocodea. There are about 5 genera and more than 100 described species in Paracaeciliidae.
Protroctopsocidae is a family of psocids in the order Psocodea. There are at least four genera and about five described species in Protroctopsocidae.
Sabulopsocidae is a family of lice in the order Psocodea. There are at least two genera and two described species in Sabulopsocidae.
Trimenoponidae is a family of lice in the order Psocodea. There are about 6 genera and 18 described species in Trimenoponidae.
Amphientometae is an infraorder of psocids, one of two major division of the Troctomorpha within the order Psocodea. There are about 7 families and at least 230 described species in Amphientometae.
