Glaresis is a genus of beetles, sometimes called "Enigmatic scarab beetles", in its own family, the Glaresidae. It is closely related to, and was formerly included in, the family Scarabaeidae. Although its members occur in arid and sandy areas worldwide, only the nocturnal adults have ever been collected, and both the larvae and biology of Glaresis are as yet unknown. Due to their narrow habitat associations, a great number of these species occur in extremely limited geographic areas, and are accordingly imperiled by habitat destruction.
Myxophaga is the second-smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.
The Cerophytidae are a family of beetles belonging to Elateroidea. Larvae are associated with rotting wood, on which they are presumed to feed. The family contains over 20 species in five genera, primarily distributed in the New World, but also in Eurasia and Africa. 17 fossil species in 7 genera are known extending to the Early Jurassic. Like some other elateroids, the adults are capable of clicking.
Pelecinidae is a family of parasitic wasps in the superfamily Proctotrupoidea. It contains only one living genus, Pelecinus, with three species known from the Americas. The earliest fossil species are known from the Jurassic, and the group was highly diverse during the Cretaceous. Members of Pelecinus are parasitic on larval beetles, flies, green lacewings, and sawflies.
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.
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.
Boganiidae is a family of beetles, in the superfamily Cucujoidea. Members of the family are found in southern Africa, Australia and New Caledonia. Adults and larvae are pollenivorous, feeding on the pollen of cycads and flowering plants of the families Myrtaceae, Meliaceae, Cunoniaceae and Elaeocarpaceae. Metacucujus and Paracucujus act as pollinators for cycads Encephalartos and Macrozamia respectively. This association with cycads goes back to at least the Mid-Cretaceous, with an extinct form being found with preserved cycad pollen in 99 million year old Burmese amber.
Helotidae is a family of beetles, in the suborder Polyphaga. The family includes about five extant genera, Helota MacLeay, Neohelota Ohta, Afrohelotina Kirejtshuk, Metahelotella Kirejtshuk, and Strophohelota Kirejtshuk. Helotidae are found mainly in the Old World tropics and are absent from Australia and Madagascar. The antennae are clubbed on the final three segments and is retractable within grooves under the head. The wings have reduced venation with just 4 anal veins. Helotids are known to be associated with sap, fruit and flowers, and the larvae of some species are known to bore into wood in order to pupate.
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.
Omma is a genus of beetles in the family Ommatidae. Omma is an example of a living fossil. The oldest species known, O. liassicum, lived during the final stage of the Triassic (Rhaetian), over 200 million years ago, though the placement of this species in Omma has been questioned. Numerous other fossil species are known from the Jurassic and Cretaceous of Europe and Asia. The only living species is Omma stanleyi, which is endemic to Australia. Three other extant species endemic to Australia that were formerly part of this genus were moved to the separate genus Beutelius in 2020.Omma stanleyi is strongly associated with wood, being found under Eucalyptus bark and exhibiting thanatosis when disturbed. Its larval stage and many other life details are unknown due to its rarity. Males are typically 14–20 mm in length, while females are 14.4-27.5 mm. Omma stanleyi occurs throughout eastern Australia from Victoria to Central Queensland.
Throscidae is a family of elateroid beetles found worldwide with around 150 species in 5 extant genera. The larvae are soil-dwelling, siphoning fluid from mycorrhizae attached to trees. The adults are short-lived, with the adult males being noted for a complex mating dance. Like some other elateroids, they are capable of clicking.
Lophocateridae is a family of beetles in the superfamily Cleroidea, formerly included in the Trogossitidae. Members of the group have a variety of ecologies, including as predators of other insects, as fungivores, or are phytophagous.

Yuripopovinidae is an extinct family of Coreoidea Hemipteran true bugs. Member species are known from the Early Cretaceous and early Late Cretaceous of Asia and northern Gondwana. Among the distinguishing characters are "the hemelytral costal vein apically much thickened and pterostigma-like, the corium with two large cells separated by one longitudinal straight vein." Dehiscensicoridae, described from the Yixian Formation of China has been deemed a junior synonym of Yuripopovinidae per Du et al. (2019). The family was named after Russian paleoentomologist Yuri Alexandrovich Popov.
Elcanidae are an extinct family of Mesozoic and early Cenozoic orthopterans. Members of the family are distinguished by the presence of spurs on the distal part of the metatibia, unique among orthopterans, these have been suggested to have been used for controlling gliding, swimming aids, or for jumping on water. The group combines characteristics from both major groups of orthopterans, with long antennae and nymphal morphology similar to Ensifera, but with wing venation and adult morphology more similar to Caelifera. Elcanidae is part of Elcanoidea, which is thought to have diverged from living orthopterans by the beginning of the Permian, around 300 million years ago. The family also includes Permelcanidae, known from the Early-Late Permian. The relationship of Elcanoidea to Ensifera and Caelifera is currently unresolved. Elcanids are known from the Late Triassic to Paleocene of Eurasia, North and South America. Some members of the group exhibited aposematic coloration.
Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
This paleoentomology list records new fossil insect taxa that are to be described during the year 2022, as well as notes other significant paleoentomology discoveries and events which occurred during that year.
