Passalidae is a family of beetles known variously as "bessbugs", "bess beetles", "betsy beetles" or "horned passalus beetles". Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20–43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles.
Scydmaeninae are a subfamily of small beetles, commonly called ant-like stone beetles or scydmaenines. These beetles occur worldwide, and the subfamily includes some 4,500 species in about 80 genera. Established as a family, they were reduced in status to a subfamily of Staphylinidae in 2009
The Anthicidae are a family of beetles that resemble ants. They are sometimes called ant-like flower beetles or ant-like beetles. The family comprises over 3,500 species in about 100 genera.
Histeridae is a family of beetles commonly known as clown beetles or Hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other Hister beetles, they must be isolated when collected.
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.
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. The family consist of two genera with about 20 species. Prostomis mandibularis is known from North America. Other species of Prostomis are found in Africa, the Pacific region and East Asia. Species of Dryocora are known from New Zealand, Australia and Tasmania.
The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles, or horned powderpost beetles. The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. Exceptions are the powderpost beetles, and members of the subfamily Psoinae.
Syntelia is a genus of middle-sized beetles described by John O. Westwood in 1864. It is the only genus in the family Synteliidae erected by George Lewis in 1882.
Lepicerus is a genus of myxophagan beetles containing three described species in the family Lepiceridae; it is the only extant genus in the family, with another genus, Lepiceratus only known from fossils. Extant species occur in the Neotropics, from Mexico south to Venezuela and Ecuador. Fossils referrable to the genus are known from the early Late Cretaceous of Southeast Asia.
Ant nest beetles or paussines, some members of which are known also as flanged bombardier beetles, are a large subfamily within the ground beetles (Carabidae). The tribes Metriini, Ozaenini, Paussini and Protopaussini are included in the subfamily.
Ektatotricha is an extinct, monotypic, genus of ant-like stone beetle in the family Staphylinidae containing the single species Ektatotricha paradoxa.
Kachinus is an extinct genus of ant-like stone beetle in the family Staphylinidae containing the single species Kachinus antennatus.
Gerontoformica is an extinct genus of stem-group ants. The genus contains thirteen described species known from Late Cretaceous fossils found in Asia and Europe. The species were described between 2004 and 2016, with a number of the species formerly being placed into the junior synonym genus Sphecomyrmodes.
New Jersey Amber, sometimes called Raritan amber, is amber found in the Raritan and Magothy Formations of the Central Atlantic (Eastern) coast of the United States. The amber is dated to be of Late Cretaceous, Turonian age, based on pollen analysis of the host formations. The amber has been known since the nineteenth century, with several of the old clay-pit sites now producing many amber specimens for study. A number of organism fossils have been described from inclusions in the amber, including fungi, plants, tardigrades, insects, and feathers. The first identified Cretaceous age ant was described from a fossil found in New Jersey in 1966.
Embolemidae is a small family of around 64 species and 3 genera distributed around the world. They are small solitary parasitoid wasps, and are parasites on planthopper nymphs of the families Achilidae and Cixiidae.
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.
2020 in paleoentomology is a list of new fossil insect taxa that were described during the year 2020, 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.
2021 in paleoentomology is a list of new fossil insect taxa that were described during the year 2021, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
