The Xiphocentronidae are a family of caddisflies. It has previously been treated as a subfamily of Psychomyiidae [1] , and has a broad distribution, including parts of Asia, Central Africa and the Americas. [1] It contains nine genera, in three subfamilies [2] : Since the subgenus Cnodocentron (Caenocentron) was elevated to genus level [3] ; and the Cretaceous fossil genus Palerasnitsynus was moved from Psychomyiidae to a new subfamily within Xiphocentronidae [2] .

The Gonorynchiformes are an order of ray-finned fish that includes the important food source, the milkfish, and a number of lesser-known types, both marine and freshwater.
The Amiiformes order of fish has only two extant species, the bowfins: Amia calva and Amia ocellicauda, the latter recognized as a separate species in 2022. These Amiiformes are found in the freshwater systems of North America, in the United States and parts of southern Canada. They live in freshwater streams, rivers, and swamps. The order first appeared in the Triassic, and the extinct members include both marine and freshwater species, many of which are morphologically disparate from bowfins, such as the caturids.
Alexandr Pavlovich Rasnitsyn is a Russian entomologist, expert in palaeoentomology, and Honored Scientist of the Russian Federation (2001). His scientific interests are centered on the palaeontology, phylogeny, and taxonomy of hymenopteran insects and insects in general. He has also studied broader biological problems such as evolutionary theory, the principles of phylogenetics, taxonomy, nomenclature, and palaeoecology. He has published over 300 articles and books in several languages. In August 2008 he was awarded the Distinguished Research Medal of the International Society of Hymenopterists.
The Ecnomidae are a family of caddisflies comprising 9 genera with a total of 375 species.
The Psychomyiidae are a family of tube-making caddisflies. Members of this family are typically very similar to polycentropodids, most of them can be differentiated by the spur formula is 2-4-4, thyridial cell short, absence of the forewing fork I, and hindwing forks I and IV. Male genitalia has elongate preanal appendages, and reduced tergum IX. The larvae differ by the submental sclerites separated, foretrochantin broad, and the pupal mandible apex whip-like. Larvae construct long silken galleries.
Dipseudopsidae is a family of caddisflies in the order Trichoptera. There are about 6 genera and at least 110 described species in Dipseudopsidae.
The Nevrorthidae are a small family of lacewings in the order Neuroptera. There are 19 extant species in four genera, with a geographically disjunct distribution: Nevrorthus, comprising 5 species with scattered distributions around the Mediterranean; Austroneurorthus, with two species known from southeastern Australia; Nipponeurorthus, comprising 11 species known from China and Japan; and Sinoneurorthus, known from a single species described from Yunnan Province, China. They are traditionally placed in the Osmyloidea, alongside Osmylidae and the spongillaflies (Sisyridae), but some research has considered them to be the sister group to the rest of Neuroptera. The larvae have unique straight jaws that are curved at the tips, and live as unspecialised predators in the sandy bottom sediments of clear, fast flowing mountain rivers and streams. They pupate underwater on the underside of stones. The adults are likely predators or feed on honeydew and other sugar-rich fluids.
Gleichenia is a genus of ferns. Its closest relative is the genus Stromatopteris, restricted to New Caledonia.
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.
Palerasnitsynus is a genus of extinct caddisfly that existed during the Late Albian Cretaceous of Myanmar. It is known from two specimens trapped in amber; one of these is of the type species Palerasnitsynus ohlhoffi, and the species of the second has not been identified.
Burmomyrma is an extinct genus of aculeate hymenopteran, suggested to be an ant. The genus contains a single described species, Burmomyrma rossi. Burmomyrma is known from a single Middle Cretaceous fossil which was found in Asia.
Dysoneuridae is an extinct family of insect in the order Trichoptera, the caddisflies. The family was first described by I.D. Sukacheva in 1968, and lived from the Middle Jurassic to mid-Cretaceous.
Phylocentropus is a genus of caddisflies in the family Dipseudopsidae. There are about 17 described species in Phylocentropus.

2017 in paleoentomology is a list of new fossil insect taxa that were described during the year 2017, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Tarachoptera is an extinct order of insects, currently solely known from the mid Cretaceous aged Burmese amber. It belongs to Amphiesmenoptera alongside living Lepidopterans and Trichoptera (caddiesflies), but is outside the clade containing the two groups, with an estimated divergence during the Upper Triassic, and therefore over a 100 million year ghost lineage. It currently contains only one family, the Tarachocelidae, which was named in a publication in 2017 a few months before the order itself was published. As the manuscript was in submission, an additional specimen belonging to a new genus justified creating a separate order. Additional species were described in 2018 and 2020. A notable character is the possession of wing scales like members of Lepidoptera, these were initially suggested to have been evolved in parallel evolution from hairs or setae, but a later study suggested that the scales of all amphiesmenopterans are homologous, sharing a common origin. Their flattened morphology and small size suggest they were adapted to living in small crevices; the morphology of the mouth suggests that they were phytophagous, and ingested small particles, perhaps including pollen grains.
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.
