Histeroidea is a superfamily of beetles in the infraorder Staphyliniformia.
Characteristic to Histeroidea are an accessory posterior ridge (locking device) behind the hind margin and presence of medial loop and apical hinge of wing. The elytra are truncate with 1 or 2 abdominal segments visible. The abdominal 8th segment is completely invaginated in the 7th segment. Each antenna has 8 (seldom 7) segments preceding a club of fused segments. The ventral body surface is glabrous. [1]
Histeroids in general are predators. However, Sphaeritidae is believed to only be predatory in the larval stage, with its adults being saprophagous instead. [2]
This superfamily occurs in various habitats. The Histeridae alone can be found in dung, carrion, fungi, leaf litter, in symbiosis with other animals (e.g. social insects), under tree bark or in galleries of wood-boring beetles. [2]
Some authors treat Histeroidea as a single family within the superfamily Hydrophiloidea (Hydrophiloidea sensu lato), as they seem to form a clade. [3] Three extant families are currently recognized:
Sphaeritidae and Synteiidae each contain just a single genus: Sphaerites and Syntelia , respectively. This makes both families monotypic.
The oldest fossils of the superfamily are Cretohister and Antigracilus from the Early Cretaceous (Aptian) Yixian Formation of China, which are more closely related to Histeridae than the other two families. [4] [5]
Spercheus is a genus of aquatic beetles which are placed in a family of their own, Spercheidae within the Hydrophiloidea. About 20 species are known from around the world except the Nearctic with the majority being from the Oriental and Afrotropical Realms.
Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species discovered thus far.
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.
Staphyliniformia is a large infraorder of beetles. It contains over 70,000 described species from all regions of the world. Most species occur in moist habitats - various kinds of rotting plant debris, fungi, dung, carrion, many live in fresh water.
The Chrysomeloidea are an enormous superfamily of beetles, with tens of thousands of species. The largest families are Cerambycidae, long-horned beetles, with more than 35,000 species, and Chrysomelidae, leaf beetles, with more than 13,000 species.
Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea. They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils.
Byrrhoidea is a superfamily of beetles belonging to Elateriformia that includes several families which are either aquatic or associated with a semi-aquatic habitat. Other than the superfamily Hydrophiloidea, most of the remaining Polyphagan beetles which are aquatic are in this superfamily.
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae, but several of the subfamilies have been removed and raised to family rank. Hydrophiliidae remains by far the largest member of the group, with nearly 3,000 described species. The other families have no more than 400 species. The Histeroidea are closely related and sometimes considered part of a sensu lato Hydrophiloidea. The majority of the clade is aquatic, which is thought to be the ancestral ecology of the group, with some lineages like Sphaeridiinae becoming secondarily terrestrial. Modern representatives of the group first appeared during the Late Jurassic.
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).
Helophorus is the only genus in the beetle family Helophoridae within the Hydrophiloidea. They are small insects, found mainly in the Holarctic region, but two or three species also live in the Afrotropical region, Central America and one in the Indomalayan region.
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.
Passandridae, the "parasitic flat bark beetles," are a family of beetles notable for being one of the very few beetle families with larvae that are, as far as known, exclusively ectoparasitic on the immature stages of other beetles and Hymenoptera.
Coccinelloidea is a superfamily of beetles in the order Coleoptera, formerly included in the superfamily Cucujoidea. There are more than 10,000 species in Coccinelloidea, including more than 6000 in the lady beetle family Coccinellidae.
Gyrininae is a subfamily of ground and water beetles in the family Gyrinidae. There are at least 740 described extant species in Gyrininae.
Anamorphidae is a family of beetles in the superfamily Coccinelloidea, formerly included within the family Endomychidae. They are found worldwide. Like enchomyids, they are fungivores, with adult and larval stages thought to exclusively consume fungal spores.
Onthophilinae is a subfamily of clown beetles in the family Histeridae. There are about 8 genera and at least 80 described species in Onthophilinae.
Phytophaga is a clade of beetles within the infraorder Cucujiformia consisting of the superfamilies Chrysomeloidea and Curculionoidea that are distinctive in the plant-feeding habit combined with the tarsi being pseudotetramerous or cryptopentamerous, where the fourth tarsal segment is typically greatly reduced or hidden by the third tarsal segment. The Cucujoidea are a sister to the Phytophaga. In some older literature the term Phytophaga was applied only to the Chrysomeloidea.
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.
Nasaltus chinensis, is a species of clown beetle found in India, Sri Lanka, Pakistan and Australia.
