The sap beetles, also known as Nitidulidae, are a family of beetles.
The Cupedidae are a small family of beetles, notable for the square pattern of "windows" on their elytra, which give the family their common name of reticulated beetles.
The telephone-pole beetle is a beetle native to the eastern United States, and the only living representative of the otherwise extinct family Micromalthidae. They have an unusual life cycle involving asexually reproducing (parthenogenetic) female larvae, as well as non-functional "ghost adults".
The Archostemata are the smallest suborder of beetles, consisting 45 living species in five families. They are an ancient lineage with a number of primitive characteristics. Antennae may be thread-shaped (filiform) or like a string of beads (moniliform). This suborder also contains the only beetles where both sexes are paedogenic, Micromalthus debilis. Modern archostematan beetles are considered rare, but were more diverse during the Mesozoic. The term "Archostemata" is used more broadly by some authors to include both modern archostematans as well as stem-group beetles like "protocoleopterans", which some modern archostematans closely resemble to due to their plesiomorphic morphology. Genetic research suggests that modern archostematans are a monophyletic group. Some genetic studies have recovered archostematans as the sister group of Myxophaga.
The Cucujidae, "flat bark beetles," are a family of distinctively flat beetles found worldwide under the bark of dead trees. The family has received considerable taxonomic attention in recent years and now consists of 70 species distributed in five genera. It was indicated Cucujus species are scavengers, only feeding on pupae and larvae of other insects and on other subcortical beetles such as their own. Since the Cucujidae prey on larvae of potentially tree damaging beetles that spread fungal diseases, they are considered to be beneficial to the health of living trees.
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.
Ascioplaga is a genus of beetles in the family Cupedidae, containing two species endemic to New Caledonia and one described from northern Queensland in Australia. The Australian species, Ascioplaga scalena, was originally described as a species of Adinolepis, and was transferred to Ascioplaga in 2009.
Priacma is a genus of beetles in the family Cupedidae. It contains a single extant species, Priacma serrata native to western North America and one fossil species, P. megapuncta from the Cenomanian aged Burmese amber. Species previously assigned to the genus from the Yixian Formation of China have been subsequently placed in the separate genus Apriacma.
Rhipsideigma is a genus of beetles in the family Cupedidae. It contains five species, four of which are endemic to Madagascar, the other being endemic to the northern coast of Tanzania. They vary in length from 13 mm to 20 mm, and are up to 6 mm wide.
Tenomerga is a genus of beetles in the family Cupedidae. This genus has about 17 extant species, which are native to the eastern Palearctic, Nearctic and Oriental regions.
Paracupes is a genus of beetles in the family Cupedidae, the reticulated beetles.
The Crowsoniellidae are a monotypic family of beetles, in the suborder Archostemata. So far, only a single species, Crowsoniella relicta, has been attributed to this family. It is known only from three male specimens collected in 1973 in Italy by Roberto Pace. In a degraded pasture, the beetles were found among the roots of a large hawthorn tree, in deep calcareous soil. No other specimens have been found since.
The Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: Omma,Tetraphalerus and Beutelius. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed on deadwood.
The Brachypsectridae are a family of beetles commonly known as the Texas beetles. There are only two extant genera, Brachypsectra and Asiopsectra. Brachypsectra has a cosmopolitan distribution, mostly in arid regions, while Asiopsectra is found in Central Asia and the Middle East.
Eumolpini is a tribe of leaf beetles in the subfamily Eumolpinae. It is the largest tribe in the subfamily, with approximately 170 genera found worldwide. Members of the tribe almost always have a longitudinal median groove on the pygidium, which possibly helps to keep the elytra locked at rest. They also generally have a subglabrous body, as well as appendiculate pretarsal claws.
Tenomerga cinerea is a species of reticulated beetle in the family Cupedidae. It is found in North America.
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.
Tasmosalpingus is the only genus in the beetle family Tasmosalpingidae. There are two species in Tasmosalpingus, found in Australia in Tasmania, Victoria and New South Wales. Adults have been collected using malaise traps, while a possible larval specimen was found under the bark of the podocarp Phyllocladus aspleniifolius. Gut contents indicate that they are mycophagous, feeding on fungal hyphae.
