Louse is the common name for members of the order Phthiraptera, which contains nearly 5,000 species of wingless insect. Lice are obligate parasites, living externally on warm-blooded hosts which include every species of bird and mammal, except for monotremes, pangolins, and bats. Lice are vectors of diseases such as typhus.
Strigiphilus garylarsoni is a species of chewing louse found only on owls. The species has no common name.
A bird louse is any chewing louse of order Phthiraptera which parasitizes warm-blooded animals, especially birds. Bird lice may feed on feathers, skin, or blood. They have no wings, and their biting mouth parts distinguish them from true lice, which suck blood.
Troctomorpha is a suborder of barklice, booklice, and parasitic lice in the order Psocoptera. There are more than 30 families and 5,800 described species in Troctomorpha.
Recent studies show the northern rockhopper penguin, Moseley's rockhopper penguin, or Moseley's penguin distinct from the southern rockhopper penguin.
Campanulotes elegans is a species of lice in the disputed, probably paraphyletic, family Philopteridae, the chewing lice, or in the family Goniodidae.
Strigiphilus is a genus of chewing louse in the suborder Ischnocera. It was circumscribed in 1910 by Eric Mjöberg.
Colpocephalum is a genus of chewing louse. Christian Ludwig Nitzsch named the genus in 1818. The Plenary Powers of the International Commission on Zoological Nomenclature selected Colpocephalum zebraBurmeister, 1838 as its type species in the 1950s. There are approximately 135 species in this genus, and they are ectoparasites of birds in at least a dozen different orders.
Rallicola is a genus of chewing louse. It is an ectoparasite of rails and other birds. It was named by Thomas Harvey Johnston and Launcelot Harrison in 1911. There are two subgenera aside from the nominotypical subgenus: Aptericola, whose species are found on kiwi birds, and Huiacola, a monospecific subgenus consisting of Rallicola extinctus, once found on the huia.
Apterygon is a genus of louse. It is endemic to New Zealand and is an ectoparasite of kiwi birds (Apteryx). Theresa Clay circumscribed the genus in 1961. In 1947, she had referred to this genus as "New Genus D", but it was not formally named as she needed to confirm the host of her specimen as well as additional material.
The Oriental Basin pocket gopher is a species of pocket gopher which is endemic to Mexico. It was first described in 1895 by Clinton Hart Merriam. It was considered to be a subspecies of Merriam's pocket gopher in the late 20th and early 21st century but has been reinstated as its own species. The IUCN Red List has evaluated it to be of least concern.
Trichodectidae is a family of louse in the suborder Ischnocera. Its species are parasites of mammals. The following 19 genera are recognized:
Harrison's rule is an observation in evolutionary biology by Launcelot Harrison which states that in comparisons across closely related species, host and parasite body sizes tend to covary positively.
Felicola is a genus of parasitic lice in the family Trichodectidae. There are at least 50 described species in Felicola.
Enderleinellidae is a family of parasitic lice in the order Psocodea. There are about 5 genera and more than 50 described species in Enderleinellidae.

Hoplopleuridae is a family of lice in the order Psocodea. There are about 6 genera and more than 150 described species in Hoplopleuridae.
Linognathidae is a family of lice in the order Psocodea. There are at least 3 genera and 70 described species in Linognathidae.
Trimenoponidae is a family of lice in the order Psocodea. There are about 6 genera and 18 described species in Trimenoponidae.
Nanopsocetae is an infraorder of psocids in the order Psocoptera. There are more than 20 families and 5,200 described species in Nanopsocetae.
