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. [1] [2] In some older literature the term Phytophaga was applied only to the Chrysomeloidea.

Phytophaga phylogeny

The diversification of species within the Phytophaga is thought to be associated with the speciation within the Angiosperms. The plant-feeding habit may have been a shift from microfungal, spore-feeding (on strobili and cycads) and saprotrophic habits. [3] With nearly 125,000 described species they are the second largest phytophagous lineage of insects after the order Lepidoptera. [4] GH45s are only encoded by the genomes possessed by the Phytophaga beetles. The derived G45s from Phytophaga degrade 3 main substances: amorphous cellulose, xyloglucan and glucomannan. It was also composed of fungal sequences, acquired by gene transfer from fungi. [5]

The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae.

<span class="mw-page-title-main">Weevil</span> Superfamily of beetles

Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.

<span class="mw-page-title-main">Polyphaga</span> Suborder of beetles

Prostomidae is a family of beetles with no vernacular common name, though recent authors have coined the name jugular-horned beetles. They are often found in dead wood.

Other species of Prostomis are found in Europe, Africa, the Pacific region and East Asia. Species of Dryocora are known from New Zealand, Australia and Tasmania.

<span class="mw-page-title-main">Corylophidae</span> Family of beetles

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.

<span class="mw-page-title-main">Endomychidae</span> Family of beetles

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.

<span class="mw-page-title-main">Trogossitidae</span> Family of beetles

Trogossitidae, also known as bark-gnawing beetles, are a small family in the superfamily Cleroidea. Many taxa formerly within this family have been removed to other families, such as Lophocateridae, Peltidae, Protopeltidae, Rentoniidae, and Thymalidae. Members of the family are generally predatory and/or feed on fungi, both in adult and larval stages, and are generally associated with wood, being found under bark or inside bored tunnel galleries. There are about 400 species in 25 genera in the family under the new, restricted circumscription, as opposed to 600 species in over 50 genera in the old definition. The oldest fossil assignable to the modern, more restricted definition of the family is Microtrogossita from the mid-Cretaceous Burmese amber of Myanmar, which has close affinities to the Trogossitini, indicating that the family had already considerably diversified by this time.

The Trictenotomidae are a small family of beetles in the superfamily Tenebrionoidea, containing fifteen species in two genera. Most species are found in the Oriental realm where they live in montane forest habitats. The family is considered, based on larval characters as well as sequence-based studies, to be closely related to the Salpingidae.

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.

Mauroniscidae is a family of cleroid beetles, formerly included in the family Melyridae. There are presently five or six genera and roughly 30 described species in Mauroniscidae, all of which are native to the Americas. Almost nothing is known about their biology.

<i>Metaxina</i> Genus of beetles

Metaxina is the only genus in the beetle family Metaxinidae. Its only species is Metaxina ornata. It endemic to the South island of New Zealand, where it is associated with sooty mold growing on Nothofagus trees. Both the larvae and adults are likely predaceous, feeding on insects and other arthropods. It is considered to be a member of the superfamily Cleroidea. Genetic studies have suggested that Metaxina should be considered a member of Chaetosomatidae, rather than constituting its own family.

<span class="mw-page-title-main">Promecheilidae</span> Family of beetles

Promecheilidae is a family of beetles in the superfamily Tenebrionoidea. Perimylopidae is considered a synonym. They are found in southern South America and associated archipelagos like South Georgia and the Falklands, New Zealand and Tasmania. Some species are associated tree ferns and moss-covered dead wood, and other forested habitats, while others are associated with peat bogs, grasslands and coastal habitats. They are probably phytophagus, feeding on lichen, moss, and other plant material.
