Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. 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.
Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus Nitellopsis, living (extant) species are placed into either one family (Characeae) or two. Further families are used for fossil members of the order. Linnaeus established the genus Chara in 1753.
Caprellidae is a family of amphipods commonly known as skeleton shrimps. Their common name denotes the threadlike slender body which allows them to virtually disappear among the fine filaments of seaweed, hydroids and bryozoans. They are sometimes also known as ghost shrimps.
Pseudicius is a genus of the jumping spiders first described by Eugène Simon in 1885. The name is combined of Greek pseudo "false" and the salticid genus name Icius. The small genus Wesolowskana should possibly be included in this genus. There is some dispute whether Afraflacilla is a distinct genus or should be included in Pseudicius. Festucula and Marchena are other close relatives, these genera form a monophyletic group.
Leptus is a genus of large mites belonging to the family Erythraeidae; they resemble members of the related genus Balaustium, but can be distinguished by the eyes, which in Leptus species are set much further forward on the body than in Balaustium species.
Abacoleptus is a genus of beetles in the family Carabidae, containing the following species: The genus was first described by Charles Adolphe Albert Fauvel in 1903.
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database which attempts to cover published genus names for all domains of life from 1758 in zoology up to the present, arranged in a single, internally consistent taxonomic hierarchy, for the benefit of Biodiversity Informatics initiatives plus general users of biodiversity (taxonomic) information. In addition to containing over 490,000 published genus name instances as at March 2020, the database holds over 1.7 million species names, although this component of the data is not maintained in as current or complete state as the genus-level holdings. IRMNG can be queried online for access to the latest version of the dataset and is also made available as periodic snapshots or data dumps for import/upload into other systems as desired.
Adurothrips is a genus of thrips in the family Phlaeothripidae, first described by Laurence Mound in 1994. There is just one species in this genus: Adurothrips atopus. The species is wingless and breeds in leaf litter in New South Wales, Queensland and South Australia.
Octurothrips is a genus of thrips in the family Phlaeothripidae, first described by Hermann Priesner in 1931. There is just one species in this genus: Octurothrips pulcher.
Lamprolina is an Australian genus of leaf beetles (Chrysomelidae) found in Victoria, New South Wales, and Queensland.
Amaryllis is a genus of amphipods belonging to the family Amaryllididae. The genus was first described in 1879 by William Aitcheson Haswell, and the type species is Amaryllis macrophthalma Haswell, 1879.
Limnoperna is a genus of bivalves belonging to the family Mytilidae.
Antipterna is a genus of moths of the family Oecophoridae, first described by Edward Meyrick in 1916.
Coptocercus crucigerus is a species of beetle in the family Cerambycidae, first described by Frederick William Hope in 1842 as Stenochorus cruciger, from a specimen collected in Port Essington (Darwin). In 1929, Herbert James Carter assigned the species to the genus Coptocercus, and also synonymised it with Phoracantha politaPascoe, 1863.
Caldicochlea is a genus of freshwater molluscs in the family, Tateidae, endemic to the mound springs of the Great Artesian Basin.
Paraproto spinosa is a species of marine amphipod in the family, Caprellidae, and was first described in 1885 by William Aitcheson Haswell as Proto spinosa. In 1903 Paul Mayer transferred the species to the newly erected genus, Paraproto, and the species became Paraproto spinosa.
Bellorchestia marmorata is a marine amphipod in the Talitridae family.
Austropheonoides is a genus of amphipods in the Cyproideidae family, and was first described in 1972 by Jerry Laurens Barnard
Halymeniales is an order of red algae belonging to the class Florideophyceae and the subclass Rhodymeniophycidae.
Aegiochus is a genus of isopods in the family Aegidae, first described in 1885 by Carl Bovallius. The type species is Aega ventrosa.
