Histeroidea
Histeroidea is a superfamily of beetles in the infraorder Staphyliniformia. Characteristics 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.Hansen, MPhylogeny and classification of the staphyliniform beetle families (Coleoptera) Biologiske Skrifter, Copenhagen, 1997 Ecology Histeroids in general are predators. However, Sphaeritidae is believed to only be predatory in the larval stage, with its adults being saprophagous instead. 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 gal ...

Synteliidae
''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, thought the Mexican species ''S. westwoodi'' has been found inside large decaying columnar cacti. Adults and larvae are predatory, feeding on insect larvae.Newton, Alfred F.. "Synteliidae Lewis, 1882: Coleoptera, Beetles". ''Handbook of Zoology Online'', edited by Andreas Schmidt-Rhaesa. Berlin, Boston: De Gruyter, 2016. A fossil species, ''Syntelia sunwukong'', is known from the Late Cretaceous ( Cenomanian) aged Burmese amber of Myanmar. Adults are around 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 ...

Sphaeritidae
''Sphaerites'' is a genus of beetles, the only genus in the family Sphaeritidae, sometimes called the false clown beetles. There are five known species, which are widespread in temperate areas of the Northern Hemisphere, found in forested or upland areas.Newton, Alfred F.. "Sphaeritidae Shuckard, 1839: Coleoptera, Beetles". ''Handbook of Zoology Online'', edited by Andreas Schmidt-Rhaesa. Berlin, Boston: De Gruyter, 2016. Adults range in length from 4.5–7 mm, with oval bodies, black but with a slight bluish-green sheen. The life histories are poorly known, but they are generally found around decaying matter and fungi. ''S. glabratus'' is associated with conifer forests in northern Europe, and seems especially attracted to sap flows from trees, feeding on the sap and then mating, with the eggs laid in sap-soaked nearby soil. The larvae have a short generation span, developing into adults within a month. It is a member of Histeroidea, making it closely related to the true ...

Staphyliniformia
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. Characteristics Most Staphyliniforms are small to average sized beetles. The diverse group has few clear apomorphies. They have primitively 11-segmented antennae, a constricted neck well behind the eyes. The pronotum has a well defined, large lateral edge. Larval legs are 5-segmented, the 10th abdominal segment is often with more-or-less fine or strong spines or hooks.

Hydrophiloidea
Hydrophiloidea, known as water scavenger beetles, is a superfamily of beetles. Until recently it included only a single family, the Hydrophilidae (water scavenger beetles), 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. Families include: * Epimetopidae * Georissidae * Helophoridae * Hydrochidae * Hydrophilidae * Spercheidae Extinct genera * †'' Laetopsia'' Fikácek et al. 2012 Yixian Formation, China, Shinekhudag Formation, Dzun-Bain Formation Mong ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histeridae
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. Characteristics The Hister beetles are easily identified by their shiny elytra which is typically shiny black or metallic green. The two main shapes for this family are ov ...

Yixian Formation
The Yixian Formation (; formerly transcribed as Yihsien Formation) is a geological formation in Jinzhou, Liaoning, People's Republic of China, that spans the late Barremian and early Aptian stages of the Early Cretaceous. It is known for its exquisitely preserved fossils, and is mainly composed of basalts interspersed with siliciclastic sediments. History Japanese occupation The potential importance of the Yixian Formation was initially recognized during the time the Empire of Japan occupied China's Rehe ("Jehol") Province after the First battle of Hopei in 1933. Many Japanese scientists had noticed fossil remains of extinct fish and reptiles, possibly the champsosaurs. These initial fossil discoveries made by Japanese scientists vanished once World War II ended in 1945. Chinese rediscovery By 1949, when administration of the area passed to the Chinese Communist Party and its leader Mao Zedong, the fossils of Yixian were studied only by Chinese scientists. It was not u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22. Stratigraphic definitions The Aptian was named after the small city of Apt in the Provence region of France, which is also known ...
