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

Calliostoma canaliculatum


Calliostoma canaliculatum, common name the channeled topsnail, is a species of small sea snail with gills and an operculum, a marine gastropod mollusk in the family Calliostomatidae, the calliostoma top snails. The name of the species "Calliostoma canaliculatum" is preoccupied in "Calliostoma", by "Calliostoma canaliculatum" , but not in "Tristichotrochus", which is where it is placed by some authors. It is currently a secondary homonym but it has not replaced the preoccupied name because the replacement name would be synonymized sooner or later.

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

Calliostoma


Calliostoma is a genus of small to medium-sized sea snails with gills and an operculum, marine gastropod molluscs within the family Calliostomatidae, the Calliostoma top snails (according to the taxonomy of Gastropoda by Bouchet & Rocroi (2005)). Previously this genus was placed within the family Trochidae. "Calliostoma" is the type genus of the family Calliostomatidae. The name of this genus is derived from the Greek words "kallos" (beautiful) and "stoma" (mouth), referring to the pearly aperture of the

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

Plant taxonomy is an empirical science, a science that determines what constitutes a particular taxon (taxonomic grouping, plural: taxa): e.g. "What plants belong to this species?" and "What species belong to this genus?". The definition of the limits of a taxon is called its 'circumscription'. For a particular taxon, if two taxonomists agree exactly on its circumscription, rank and position (i.e. the

Calliostoma


The North Atlantic topshell "Calliostoma occidentale" has been reported to feed on coelenterates. Contrary to what is the case in most other top shells, "Calliostoma" deposits its eggs in gelatinous ribbons that are only fertilized "after" being deposited. The young emerge as small snails (Lebour, 1936) without passing through a free-living planktonic stage as a veliger larva. The rather thin, acute, coeloconoid (= approaching conical shape but with concave sides) shell is imperforate or rarely umbilicate. The whorls are smooth,

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.

2004 Guido Poppe created together with his son Philippe Poppe (1977–) the journal, "Visaya", specialising in the taxonomy of Mollusca. He named the calliostoma topsnail "Calliostoma philippei", another sea snail "Calliotropis philippei" and "Bayerotrochus philpoppei" after his son. Guido Poppe named the topsnail "Calliostoma mariae" after his mother Maria Peyskens. In 1999 with Klaus Groh, he started the prestigious series "A Conchological Iconography", which today is one of the biggest compilations of its time. The following

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.

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.

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.

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 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 "

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.

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

The columella is simple, usually ending anteriorly in a slight tooth. The nucleus appears to be either dextral or sinistral indifferently. Currently, "Calliostoma" is being treated in WoRMS as a broad genus. It is expected to be broken up and (some) subgenera will be elevated to the status of genus.

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 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 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

Just at or just below the periphery there is a group of lirulae, closer and smaller than those of the upper surface. The rest of the base is regularly granose-lirate. The spire is longer and more elevated than in "Calliostoma punctulatum", and more concave in outline. The apex is acute. The sutures are very slightly impressed. There are about nine, flattened whorls. The

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.

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
