Ideally, a taxon is intended to represent a clade, that is, the phylogeny of the organisms under discussion, but this is not a requirement. A classification in which all taxa have formal ranks cannot adequately reflect knowledge about phylogeny. Since taxon names are dependent on ranks in traditional Linnaean systems of classification, taxa without ranks cannot be

Form (botany)


In botanical nomenclature, a form ("forma", plural "formae") is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the

Infraspecific name


In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon. (A "taxon", plural "taxa", is a group of organisms to be given a particular name.) The scientific names of botanical taxa are regulated by the "International Code of Nomenclature for algae, fungi, and plants" (ICN). This specifies a 'three part name' for infraspecific taxa, plus a 'connecting term' to indicate the rank of the name

Taxon


In biology, a taxon (plural taxa; back-formation from "taxonomy") is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is not uncommon, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given

PhyloCode


content of a taxon, other than the type, is not specified by the rank-based codes. In contrast, under phylogenetic nomenclature, the content of taxa are delimited using a definition that is based on phylogeny (i.e., ancestry and descent) and uses specifiers (e.g., species, specimens, apomorphies) to indicate actual organisms. The formula of the definition indicates an ancestor. The defined taxon, then, is that ancestor and all of its descendants. Thus, the content of a phylogenetically defined taxon relies on

There are no rules for how many species should make a genus, a family, or any other higher taxon (that is, a taxon in a category above the species level). It should be a natural group (that is, non-artificial, non-polyphyletic), as judged by a biologist, using all the information available to them. Equally ranked higher taxa in different phyla are not necessarily equivalent (e.g., it

Phylogenetic nomenclature, often called cladistic nomenclature, is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional approach, in which taxon names are defined by a "type", which can be a specimen or a taxon of lower rank, and a description in words. Phylogenetic nomenclature is currently not regulated, but the "International Code of Phylogenetic Nomenclature" ("PhyloCode") is intended to regulate it once it is ratified.

there are two or more legitimate names for the same taxon (with the same circumscription, position and rank), then the correct name is the one which has priority, i.e. it was published earliest, although names may be conserved if they have been very widely used. Validly published names other than the correct name are called synonyms. Since taxonomists may disagree as to the circumscription, position or rank of a taxon, there can be more than one correct name for a particular plant. These may also be called synonyms.

any biological domain, but traditionally it was always used for animals, whereas "Division" was traditionally often used for plants, fungi, etc. A prefix is used to indicate a ranking of lesser importance. The prefix "super-" indicates a rank above, the prefix "sub-" indicates a rank below. In zoology the prefix "infra-" indicates a rank below "sub-". For instance, among the additional ranks of class are superclass, subclass and infraclass. Rank is relative, and restricted to a particular

a particular taxon and rank. Nevertheless, invalid names ("nomen invalidum", "nom. inval.") are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason for this is that a taxonomist intends to write a "magnum opus" that provides an overview of the group, rather than a series of small papers. Another reason is that the code of nomenclature changes with time, and

Aromobatidae


The Aromobatidae are a family of frogs native to Central and South America. They are sometimes referred to as cryptic forest frogs. They are the sister taxon of the Dendrobatidae, the poison dart frogs, but are not as toxic as most dendrobatids are. The Aromobatidae were separated from the Dendrobatidae only in 2006, and some sources continue to treat these frogs as part of the Dendrobatidae. However, their position as the sister taxon is well supported, and the question is primarily about whether they should be ranked as a family or

The taxon was first published as subgenus of "Mormopterus" in 2014, separating Australian groups whose diversity was reviewed and described as new species. The content of the new taxon was established or formerly cryptic taxa of Indo-Papuan species and a centre of diversity at the Australian mainland. This was elevated to the rank of genus in 2015.

For plants, it was proposed by Herman Johannes Lam in 1948, and it was adopted at the VII International Botanical Congress, held in 1950. The Glossary of the "International Code of Zoological Nomenclature" (1999) defines a A taxon can be assigned a taxonomic rank, usually (but not necessarily) when it is given a formal name.

But as neither the type nor the final epithet has changed, there is no need for a change in author citation. The same goes for a subdivision of a genus.

Monera () (Greek - μονήρης (monḗrēs), "single", "solitary") is a kingdom that contains unicellular organisms with a prokaryotic cell organization (having no nuclear membrane), such as bacteria. They are single-celled organisms with no true nuclear membrane (prokaryotic organisms). The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866. Subsequently, the phylum was elevated to the rank of kingdom in 1925 by Édouard Chatton. The last commonly accepted mega-classification with the taxon

Bolton (2003) was the first to suggest the taxonomic instability of "Tatuidris" within Myrmicinae and raised the genus to the level of a new subfamily, the Agroecomyrmecinae, suggesting that Agroecomyrmecinae might be the sister taxon to Myrmicinae. The subfamily rank was re-assessed by Baroni Urbani & de Andrade in 2007, this was the first attempt to include "Tatuidris" as a terminal taxon in a morphological cladistic analysis. In their study, Baroni Urbani & de Andrade identified

Correct name


In botany, the correct name according to the International Code of Nomenclature for algae, fungi, and plants (ICN) is the one and only botanical name that is to be used for a particular taxon, when that taxon has a particular circumscription, position and rank. Determining whether a name is correct is a complex procedure. The name must be validly published, a process which is defined in no less than 16 Articles of the ICN. It must also be "legitimate", which imposes some further requirements. If

Abelisauridae


. Abelisauridae is a family in rank-based Linnaean taxonomy, within the infraorder Ceratosauria and the superfamily Abelisauroidea, which also contains the family Noasauridae. It has had several definitions in phylogenetic taxonomy. It was originally defined as a node-based taxon including "Abelisaurus", "Carnotaurus", their common ancestor, and all of its descendants. Later, it was redefined as a stem-based taxon, including all animals more closely related to "Abelisaurus" (or the more complete "Carnotaurus") than to "

-shaped hairs. There is some dispute about ranking these ferns. They are typically placed in the order Gleicheniales. They may alternatively be considered a subclass Gleicheniatae or class Gleichenopsida, so that a distinct taxon can be established for the leptosporangiate ferns. In this case, the Gleicheniaceae are upranked to an order and receive the name Gleicheniales. Irrespective of their modern taxonomic treatment, the Gleicheniaceae were formerly included in the order Polypodiales. But the ferns in the loose sense are much too diverse a group to be shoehorned into one taxon

Taxonomic rank


by the nomenclature codes. There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, "domain" (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for dominion (lat. dominium), introduced by Moore in 1974. A taxon is usually assigned a rank when it is given its formal name. The basic ranks are species and

Taxonomic rank


In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank

The "International Code of Zoological Nomenclature" defines "rank" as: "The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g. all families are for nomenclatural purposes at the same rank, which lies between superfamily and subfamily)." In his landmark publications, such as the "Systema Naturae", Carl Linnaeus used a ranking scale limited to: kingdom, class, order, genus, species, and one rank below species. Today, nomenclature is regulated

Sorbeoconcha


Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda. The taxon Sorbeoconcha was named by Winston Ponder and David R. Lindberg in 1997. According to the older taxonomy by Ponder and Lindberg the suborders within the order Sorbeoconcha are: In the taxonomy by Bouchet & Rocroi (2005), the clade Sorbeoconcha was declared a taxon of unspecified rank, within the clade Caenogastropoda. It comprises the superfamily Cerithioidea, the superfamily Campaniloidea, the informal group Ptenoglossa and the clade

Stomatellinae


Stomatellinae is a subfamily of small sea snails with a brilliantly nacreous interior of the shell, marine gastropod mollusks in the family Trochidae, the top snails. In the earlier classification used in the Treatise on Invertebrate Paleontology, the Stomatellidae was included in the Archaeogastropoda, however, this taxon is now largely abandoned in favor of the more recently defined Vetigastropoda. According to Bouchet & Rocroi (2005), Williams et al. (2008) and Williams et al. (2010) this taxon underwent a rank change from family Stomatellidae to

The affinities within the families Hipposideridae and Rhinolophidae are sometimes found to be contrary in morphological and molecular analyses, yet resolving the phylogeny of these speciose and poorly defined groups has implication in several areas of research. The synonymy includes earlier combinations that elevated the rank through subtribe, tribe then subfamily. The taxon Triaenopini Benda & Vallo, 2009 was also reduced to a synonym for this family by the authors of the 2014 revision that elevated this taxon. The hipposiderid and rhinolophid bats are of especial interest to research into potential

Hutterer referred the subfossil remains from La Gomera to two subspecies of "Gallotia simonyi" with the differences being size related. He named these "Gallotia simonyi bravoana" and "Gallotia simonyi gomerana". Bischoff (1998) synonymized them to a single taxon. Barbadillo "et al." (1999) decided for "bravoana" when they elevated the taxon to species rank. Nogales "et al." (2001) concurred as regards species status,

Forsskål at first gave the new taxon subspecies status as "Scomber ferdau bajad", relating it to the mackerels, and especially "Scomber ferdau", which would later also be transferred to "Carangoides". The taxon was later given a species rank, becoming "Scomber bajad", then "Caranx bajad", before being transferred to its current position as "Carangoides bajad". The species was also independently renamed three times

monograph of the family and recognizing this taxon as a series under section "Rossolis". In 1996, taxonomist Jan Schlauer argued for the recognition of this taxon at the rank of subgenus, noting that these closely related species share many affinities with subgenus "Drosera" but are different enough to warrant subgeneric status. All species in this subgenus are native to northern Australia except for "D. petiolaris", which is more widely distributed to as far as New Guinea. The plants in this subgenus or "petiolaris"-complex mostly look like variations

Synonym (taxonomy)


Given that the correct name of a taxon depends on the taxonomic viewpoint used (resulting in a particular circumscription, position and rank) a name that is one taxonomist's synonym may be another taxonomist's correct name (and "vice versa"). Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to become one, a species is moved to a different genus, a variety is moved to a

Name-bearing type


for example, the Central American rodent tribe Nyctomyini has "Nyctomys" as its type genus and its name consists of the stem of the type genus, Nyctomy-, and the appropriate ending for a tribe, -ini. "Genus group" ranks consist of the genus and subgenus. The name-bearing type for a genus-group taxon is the type species, which must be one of the species included when that taxon ("genus" hereafter for brevity) was first formally named or, when no species were included when

Botanical name


names may also have an extra component, bringing a maximum of four parts: A botanical name in three parts, i.e., an infraspecific name (a name for a taxon below the rank of species) needs a "connecting term" to indicate rank. In the "Calystegia" example above, this is "subsp.", for subspecies. In botany there are many ranks below that of species (in zoology there is only one such rank, subspecies, so that this "connecting term" is not used in

Two species ("T. serratus" and "T. flabellatus") stood apart from these groups. By 1933, and his revision of the landmark 1907 Hatcher-Marsh-Lull monograph of all known ceratopsians, he retained his two groups and two unaffiliated

Class (biology)


In biological classification, class () is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class fitting between phylum and order. The class as a distinct rank of biological classification having its own distinctive name (and not just called a "top-level genus" "(genus summum)") was first introduced by the

The new rank insignia was nicknamed "the blue pickle". The rank is equivalent to Warrant Officer Junior Grade (WOJG) which is today's Warrant Officer (NATO grade: W-1). Enlisted and aviation cadet trainees who successfully passed air qualification training were appointed as

Taxon in disguise


In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade. While the term is from bacteriology, parallel examples are found throughout the tree of life. E.g. four-

Taxonomy (biology)


In biology, taxonomy () is the science of naming, defining (circumscribing) and classifying groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a super-group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class,

Signal Transfer Point


. SEPs send signaling messages to other SEPs, but the messages are normally routed via the SEP's adjacent STPs. An STP's main function is to identify the best path for two SEPs to communicate. A typical application would be for two SEPs to agree on the use of a shared data path (e.g., using ISUP to initiate a voice call between a user on one SEP and a user on the second SEP). In this way, STPs route signaling messages (for starting, maintaining or finishing any kind of

"T. horridus"-"T. prorsus"-"T. brevicornus" was now thought to be the most conservative lineage, with an increase in skull size and a decrease in nasal horn size, and "T. elatus"-"T. calicornis" was defined by large brow horns and small nasal horn.

calls originated by the SEPs' attached users) while avoiding disabled intermediary STPs. A signaling message typically never goes directly from a given SEP to the destination SEP: the message would normally have to pass through the initiating SEP's adjacent STP so that it can be routed to the destination SEP. In some applications, however, SEPs might be directly connected with signaling links; this would typically be done to enhance robustness or performance between two critical SEPs. Such mesh network configurations are also common in Europe, where STPs have not

Variety (botany)


In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. The pincushion cactus, "Escobaria vivipara" , is a wide-ranging variable species occurring from Canada to Mexico, and found

Lehman added the old Lull-Sternberg lineages combined with maturity and sexual dimorphism, suggesting that the "T. horridus"-"T. prorsus"-"T. brevicornus" lineage was composed of females, the "T. calicornis"-"T. elatus" lineage was made up of males, and the "T. obtusus"-"T. hatcheri" lineage was of pathologic old males. His reasoning was that males had taller, more erect horns and larger skulls, and females had smaller skulls with shorter, forward-facing horns. These findings were contested a few years later by Catherine Forster, who reanalyzed "
