A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and genus. When an organism is given a species name it is assigned to a genus, and the genus name is part of the species name. The species name is also called a binomial, that is, a two-term name.
The type genus for a family-group name is simply the genus that provided the stem to which was added the ending "-idae" (for families). Example: The family name Spheniscidae has as its type genus the genus Spheniscus Brisson, 1760. The type species for a genus-group name is more complicated and follows exactly defined provisions in articles 67 ...
[3] [4] As at 2019, the Index contained over 2 million newly published names from 1758 onwards (with a small gap around the period 1850-1864 corresponding to the difference between the end of coverage of Index Animalium and the commencement of the "Zoological Record"), out of a total complement of over 5 million name instances, each with an ...
There are some rules for names above the rank of superfamily, but the principle of priority does not apply to them, and the principle of typification is optional. These names may be either automatically typified names or be descriptive names. [36] [37] In some circumstances, a taxon has two possible names (e.g., Chrysophyceae Pascher, 1914, nom ...
English: This graph shows the main taxonomic ranks: domain, kingdom, phylum, class, order, family, genus, and species. This graph demonstrates how taxonomic ranking is used to designate related animals, the example used here is the red fox (Vulpes vulpes).
The hierarchy of biological classification's eight major taxonomic ranks. Intermediate minor rankings are not shown. In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. [1] [2] It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe.
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
An "authority" may be placed after a scientific name. [94] The authority is the name of the scientist or scientists who first validly published the name. [94] For example, in 1758, Linnaeus gave the Asian elephant the scientific name Elephas maximus, so the name is sometimes written as "Elephas maximus Linnaeus, 1758". [95]
