The spider family Liphistiidae was first recognized by Tamerlan Thorell in 1869. When narrowly circumscribed, it comprises a single genus Liphistius, native to Southeast Asia; as of April 2024, this was the circumscription accepted by the World Spider Catalog. The family contains the most basal living spiders, belonging to the suborder Mesothelae. The family has also been circumscribed more broadly to include the family Heptathelidae as a subfamily, Heptathelinae, with the narrowly circumscribed Liphistiidae becoming the subfamily Liphistiinae.
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.
Snakeflies are a group of predatory insects comprising the order Raphidioptera with two extant families: Raphidiidae and Inocelliidae, consisting of roughly 260 species. In the past, the group had a much wider distribution than it does now; snakeflies are found in temperate regions worldwide but are absent from the tropics and the Southern Hemisphere. Recognisable representatives of the group first appeared during the Early Jurassic. They are a relict group, having reached their apex of diversity during the Cretaceous before undergoing substantial decline.
The Lymexylidae, also known as ship-timber beetles, are a family of wood-boring beetles. Lymexylidae belong to the suborder Polyphaga and are the sole member of the superfamily Lymexyloidea.
The family Oedemeridae is a cosmopolitan group of beetles commonly known as false blister beetles, though some recent authors have coined the name pollen-feeding beetles. There are some 100 genera and 1,500 species in the family, mostly associated with rotting wood as larvae, though adults are quite common on flowers. The family was erected by Pierre André Latreille in 1810.
Timema is a genus of relatively short-bodied, stout and wingless stick insects native to the far western United States, and the sole extant member of the family Timematidae. The genus was first described in 1895 by Samuel Hubbard Scudder, based on observations of the species Timema californicum.
The Phasmatidae are a family of the stick insects. They belong to the superfamily Anareolatae of suborder Verophasmatodea.
Compsocidae is a family of Psocodea belonging to the suborder Troctomorpha. The family comprises two extant species in two genera, both found in Mesoamerica. Compsocus elegans is found in Mexico and Central America, while Electrentomopsis variegata is found in Mexico. The antennae of each species have 13 or 14 segments. Two extinct genera, Burmacompsocus and Paraelectrentomopsis are known from the Cenomanian aged Burmese amber of Myanmar and Albian aged Spanish amber.
Spirostreptida is an order of long, cylindrical millipedes. There are approximately 1000 described species, making Spirostreptida the third largest order of millipedes after Polydesmida and Chordeumatida.
Syntelia is a genus of beetles. It is the only genus in the family Synteliidae. There are seven known species, which are native to high-elevation regions in southern North America from central Mexico to Guatemala, and in eastern Asia, from India to Japan and eastern Russia. They are generally associated with rotting logs, typically found under bark, though the Mexican species S. westwoodi has been found inside large decaying columnar cacti. Adults and larvae are predatory, feeding on insect larvae. A fossil species, Syntelia sunwukong, is known from the Late Cretaceous (Cenomanian) aged Burmese amber of Myanmar. Adults are around 1–3.5 centimetres (0.39–1.38 in) in length. The characteristics of the family and genus include geniculate antennae with 3-segmented club, elongate body, narrowly separated coxae and tarsi with bisetose empodia. Only one abdominal segment is exposed behind elytra. The genus described by John O. Westwood in 1864, while the family was erected by George Lewis in 1882. They are members of Histeroidea, which also includes clown beetles (Histeridae).
Micropterigoidea is the superfamily of "mandibulate archaic moths", all placed in the single family Micropterigidae, containing currently about twenty living genera. They are considered the most primitive extant lineage of lepidoptera, and the sole superfamily in the suborder Zeugloptera. The name comes from the Greek for mikros, little and pterux, a wing. Unique among the Lepidoptera, these moths have chewing mouthparts rather than a proboscis, and are seen feeding, often in large aggregations, on the pollen of the flowers of many herbaceous plants, shrubs and trees. The fossil record of the group goes back to the middle-late Jurassic with the earliest known species being Auliepterix from the Karabastau Formation in Kazakhstan.
Myanmymar is an extinct genus of fairyfly preserved in Burmese amber from Myanmar. It has only one species, Myanmymar aresconoides. It is dated to the earliest part of the Cenomanian stage of the Late Cretaceous, around 99 million years old. As of 2011, it is the oldest known fossil mymarid.
The Tridactylidae are a family in the insect order Orthoptera. They are small, mole-cricket-like insects, almost always less than 20 mm (0.79 in) long when mature. Generally they are shiny, dark or black, sometimes variegated or sandy-coloured. They commonly live in short tunnels and are commonly known as pygmy mole crickets, though they are not closely related to the true "mole crickets" (Ensifera), as they are included in the Caelifera suborder.
Callipodida is an order of millipedes containing around 130 species, many characterized by crests or ridges.

Permopsocida is an extinct order of insects known from the Carboniferous (Moscovian) to the Mid-Cretaceous. It is part of Paraneoptera, alongside bark lice, bugs and thrips. Within Paraneoptera it is considered to be closer to the clade containing bugs and thrips rather than bark lice, with an estimated divergence during the Late Carboniferous. The group was first named as a suborder by Robert John Tillyard in 1926, and was raised to a full order by Huang et al. in 2016. It is currently divided up into three families, Psocidiidae which is known from the Permian to Liassic. Permopsocidae which is only known from the Permian, and Archipsyllidae, which is known from the Late Triassic to mid-Cretaceous (Cenomanian). While most members of the group are known from compression fossils, several members of Archipsyllidae are 3 dimensionally preserved in Burmese amber, which has helped clarify the morphology and phylogenetic position of the group. The morphology of the mouthparts suggests that they were capable of suction feeding and chewing, with preserved angiosperm pollen grains in the gut of Psocorrhyncha suggesting that at least some members of the group were pollenivorous.
2015 in paleoentomology is a list of new fossil insect taxa that were described during the year 2016, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
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.
