A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
The longhorn beetles are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The family is large, with over 26,000 species described, slightly more than half from the Eastern Hemisphere. Several are serious pests. The larvae, called roundheaded borers, bore into wood, where they can cause extensive damage to either living trees or untreated lumber. A number of species mimic ants, bees, and wasps, though a majority of species are cryptically colored. The rare titan beetle from northeastern South America is often considered the largest insect, with a maximum known body length of just over 16.7 cm (6.6 in). The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.
The Federation of Independents was a German nationalist and national-liberal political party in Austria active from 1949 to 1955. It was the predecessor of the Freedom Party of Austria (FPÖ).
Walter M. Yust was an American journalist and writer. Yust was also the American editor-in-chief of the Encyclopædia Britannica from 1938 to 1960. He was the father of filmmaker Larry Yust and Jane Yust Rivera. A graduate of the University of Pennsylvania, Yust began his career as a writer for the Philadelphia Evening Ledger in 1917 and later worked for newspapers in New Orleans, Louisiana, and for other publications. Yust became the literary editor of the Philadelphia Public Ledger in 1926. Three years later, upon writing a review of the new 14th edition of the Encyclopædia Britannica, Yust came to the attention of its president, William Cox. The following year Yust began to work for the encyclopaedia and became its associate editor in 1932. He served as editor in chief from 1938 until his retirement in 1960.
Trombicula is a genus of harvest mites in the Trombiculidae family. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching. These relatives of ticks are nearly microscopic, measuring 0.4 mm (0.01 in) and have a chrome-orange hue. A common species of harvest mite in North America is Trombicula alfreddugesi; in the UK, the most prevalent harvest mite is Trombicula autumnalis.
Miacids are extinct primitive carnivoramorphans within the family Miacidae that lived during the Paleocene and Eocene epochs, about 62–34 million years ago. Miacids existed for approximately 28 million years.
Marasmius is a genus of mushroom-forming fungi in the family Marasmiaceae. It contains about 500 species of agarics, of which a few, such as Marasmius oreades, are edible. However, most members of this genus are small, unimpressive brown mushrooms. Their humble appearance contributes to their not being readily distinguishable to non-specialists, and they are therefore seldom collected by mushroom hunters. Several of the species are known to grow in the characteristic fairy ring pattern.
Cheyletiella is a genus of mites that live on the skin surface of dogs, cats, and rabbits,
Cidaris is a genus of pencil sea urchins.
The intermediate parakeet or Rothschild's parakeet was a kind of parakeet reported from the sub-Himalayan region of India and was described on the basis of about seven undated specimens. Similar individuals have been noted in captivity and the type specimen is now believed to be a hybrid between Psittacula himalayana and Psittacula cyanocephala. More recent captive specimens that appeared similar were found to be hybrids produced by crosses between Psittacula krameri and Psittacula cyanocephala. An analysis of the characters of the specimens suggests that the originally described P. intermedia was a hybrid between P. cyanocephala x P. himalayana.
Lepturinae, the lepturine beetles, is a subfamily of the longhorn beetle family (Cerambycidae), containing about 150 genera worldwide. This lineage is most diverse in the Northern Hemisphere. Until recently the subfamily Necydalinae was included within the lepturines, but this has been recently recognized as a separate subfamily. Nine tribes are usually recognized today, with a tenth, Caraphiini, created in 2016. A few genera are of uncertain placement within the subfamily.
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms.
Otobius is a genus in the soft-bodied tick family, Argasidae. While similar to the genus Ornithodoros it is characterized by a vestigial hypostome (tick) in adults, despite being developed in nymphs, in addition to the absence of both eyes and hood.
Mecistocephalidae is a family of centipedes in the order Geophilomorpha, containing the following genera:
Habronema is a genus of nematodes in the order Spirurida.
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database containing the scientific names of the genus, species, and higher ranks of many plants, animals and other kingdoms, both living and extinct, within a standardized taxonomic hierarchy, with associated machine-readable information on habitat and extant/fossil status for the majority of entries. The database aspires to provide complete coverage of both accepted and unaccepted genus names across all kingdoms, with a subset only of species names included as a lower priority. In its March 2019 release, IRMNG contained 490,095 genus names, of which 236,514 were listed as "accepted", 120,194 "unaccepted", 7,391 of "other" status i.e. interim unpublished, nomen dubium, nomen nudum, taxon inquirendum or temporary name, and 125,996 as "uncertain". The data originate from a range of print, online and database sources, and are reorganised into a common data structure to support a variety of online queries, generation of individual taxon pages, and bulk data supply to other biodiversity informatics projects. IRMNG content can be queried and displayed freely via the web, and download files of the data down to the taxonomic rank of genus as at specific dates are available in the Darwin Core Archive (DwC-A) format. The data include homonyms, including both available and selected unavailable names.
Palmaria is a genus of algae. One of its most notable members is dulse, Palmaria palmata.
