Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far.
Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea. They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils.
Corylophidae is a family of minute hooded beetles, sometimes called minute fungus beetles, in the superfamily Coccinelloidea. There are about 18 genera and at least 120 described species in Corylophidae. They feed on microfungi such as molds, and are often found associated with bark, as well as in leaf litter and other decaying vegetation. In older literature, the family name was often given as Orthoperidae.
Endomychidae, or handsome fungus beetles, is a family of beetles with representatives found in all biogeographic realms. There are around 120 genera and 1300 species. The family was established based on the type genus Endomychus, a genus erected in 1795 by Panzer which was applied to a species that Linnaeus called Chrysomela coccinea. As the common name suggests, Endomychidae feed on fungi. Crowson, in his influential treatment of the beetles, placed the family within the Cucujoidea. They have a tarsal formal of 4-4-4 or 3-3-3 and the wings lack a closed radial cell. The second antennal segment has a sensory appendage that is as long as the third antennal segment. The family has also been grouped with the Coccinellidae in a group called the Trimera for having pseudotrimerous tarsi. A 2015 molecular phylogeny study found that the Cucujoidea were found to be non-monophyletic and the Endomychidae was refined with the removal of the Anamorphinae from within the family and elevated to the status of a full family, Anamorphidae. Mycetaeinae and Eupsilobiinae were also found not to belong within the clades of the core Endomychidae, and likewise reclassified into the families Mycetaeidae and Eupsilobiidae.
Bothrideridae is a family of beetles in the superfamily Coccinelloidea. They are known commonly as the cocoon-forming beetles or dry bark beetles. They occur worldwide with most native to the Old World tropics. In older literature, the family was often included in the family Colydiidae, but is now considered unrelated.
Hymaea is a genus of beetles in the family Phloeostichidae.
Anommatus duodecimstriatus is a species of beetle in family Teredidae. It is found in the Palearctic region.
Coccinelloidea is a superfamily of beetles in the order Coleoptera, formerly included in the superfamily Cucujoidea. There are more than 10,000 species in Coccinelloidea, including more than 6000 in the lady beetle family Coccinellidae.
Teredidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Bothrideridae. There are around 160 species in 10 genera, found worldwide except South America. Teredids are generally found under bark, in the galleries of wood-boring beetles, or in leaf litter. They are thought to be fungivores. The oldest records of the family are Delteredolaemus from mid-Cretaceous aged Burmese amber from Myanmar and a species of Teredolaemus from Eocene aged Baltic amber.
Anamorphidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. They are found worldwide. Like enchomyids, they are fungivores, with adult and larval stages thought to exclusively consume fungal spores.
Eupsilobiidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. Most genera are restricted to the Neotropics, while the genus Eidoreus is found worldwide. They are fungivores, and have been observed living commensally in bee and ant nests.
Bystus is a genus of beetles in the family Anamorphidae. There are about six described species in Bystus.
Eidoreus is a genus of beetles in the family Eupsilobiidae. There are at least two described species in Eidoreus.
Clemmus is a genus of beetles in the family Anamorphidae. There are at least two described species in Clemmus.
Mycetaea is a genus of beetles in the family Mycetaeidae. There is at least one described species in Mycetaea, M. subterranea.
Mychocerinus is a genus of beetles in the family Murmidiidae. There are at least two described species in Mychocerinus.
Rustleria is a genus of beetles in the family Teredidae. There is one described species in Rustleria, R. obscura.
Oxylaemus is a genus of beetles in the family Teredidae. There are at least three described species in Oxylaemus.
Illeis is a genus of ladybird beetles in the family Coccinellidae. There are around 14 described species in Illeis, found in south and southeast Asia, and in Oceania.
Phytophaga is a clade of beetles within the infraorder Cucujiformia consisting of the superfamilies Chrysomeloidea and Curculionoidea that are distinctive in the plant-feeding habit combined with the tarsi being pseudotetramerous or cryptopentamerous, where the fourth tarsal segment is typically greatly reduced or hidden by the third tarsal segment. The Cucujoidea are a sister to the Phytophaga. In some older literature the term Phytophaga was applied only to the Chrysomeloidea.
