In taxonomy, a superseded combination is a notice of change to the binomial nomenclature of the accepted name of a species. This happens when a species is moved to a new genus after the initial species description. [2] The original name is called a superseded combination, [3] and the new name is called the new combination, [4] or comb. nov.. [5]
Some but not all superseded combinations are basionyms, and some basionyms are not superseded combinations. [6] The superseded combination is not the same as a synonym and technically should not be called one. [4]
If the species is moved again to a third genus, both of the older names are considered superseded combinations. The original name is the superseded original combination and the second name is the superseded recombination. [4] If the species were moved back to a previous genus, the International Commission on Zoological Nomenclature would not consider the current name to be a new combination. [7]
The specific epithet is kept in all these name changes, [3] with perhaps some modification of the suffix to harmonize with the genus name.
For example, in 1766 Peter Simon Pallas described a new species of marine polychaete worm he called Aphrodita flava. [8] In 1867, that name became a superseded (original) combination when Hjalmar Kinberg moved the species to Thesmia , creating the new combination Thesmia flava. [9] The genus Thesmia was later synonymized with Chloeia , [10] creating a new combination of Chloeia flava [11] Aphrodita flava is the superseded original combination, Thesmia flava is the superseded subsequent recombination, and the current name Chloeia flava is the new combination. [11]
In taxonomy, binomial nomenclature, also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name, or a scientific name; more informally it is also historically called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called binominal nomenclature, with an "n" before the "al" in "binominal", which is not a typographic error, meaning "two-name naming system".
The International Code of Nomenclature for algae, fungi, and plants is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants". It was formerly called the International Code of Botanical Nomenclature (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the Melbourne Code which replaced the Vienna Code of 2005.
In the scientific name of organisms, basionym or basyonym means the original name on which a new name is based; the author citation of the new name should include the authors of the basionym in parentheses. The term "basionym" is used in both botany and zoology. In zoology, alternate terms such as original combination or protonym are sometimes used instead. Bacteriology uses a similar term, basonym, spelled without an i.
A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."
Aphrodita is a genus of marine polychaete worms found in the Mediterranean Sea and the Atlantic Ocean.
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 there are two or more legitimate names for the same taxon, 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.
In botany, an infraspecific name is the scientific name for any taxon below the rank of species, i.e. an infraspecific taxon or infraspecies. 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. An example of such a name is Astrophytum myriostigma subvar. glabrum, the name of a subvariety of the species Astrophytum myriostigma.
In zoological nomenclature, the specific name is the second part within the scientific name of a species. The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is Homo sapiens, which is the species name, consisting of two names: Homo is the "generic name" and sapiens is the "specific name".
In biological nomenclature, a nomen novum, new replacement name is a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons. It does not apply when a name is changed for taxonomic reasons. It is frequently abbreviated, e.g.nomen nov., nom. nov..
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently.
Eunice is a genus in the polychaete family Eunicidae. Individuals grow to a length of between 0.5 and 300 cm. Their bodies have multiple segments. They have two eyes and five tentacles. They have well-developed sense organs and relatively large brains. Their color is dark purple-brown to red-brown with a white ring at the fourth segment. They are found in oceans and seas around the world. They have an evertible proboscis with distinctive mouthparts, some of which comprise two rows of maxilliary plates in a radula-like fashion.
Combinatio nova, abbreviated comb. nov., is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not be confused with species nova, used for a previously unnamed species. The new combination replaces the superseded combination.
Diopatra is a genus of polychaete worms in the family Onuphidae.
This is a list of terms and symbols used in scientific names for organisms, and in describing the names. For proper parts of the names themselves, see List of Latin and Greek words commonly used in systematic names. Note that many of the abbreviations are used with or without a stop.
Amphinomidae, also known as the fireworms, bristle worms or sea mice, are a family of marine polychaetes, many species of which bear chaetae mineralized with carbonate. The best-known amphinomids are the fireworms, which can cause great pain if their toxin-coated chaetae are touched or trodden on. Their relationship to other polychaete groups is somewhat poorly resolved.
Chloeia is a genus of marine polychaete worms.
Terebellides is a genus of polychaete worms in the family Trichobranchidae.
Gattyana is a genus of marine annelids in the family Polynoidae. The genus includes 11 species, 9 of which occur in the northern hemisphere, the remaining two are from the Indian Ocean off Mozambique and the Southern Ocean off New Zealand. Species of Gattyana are known from shallow water down to depths of about 1200 m.
Hermodice is a genus of annelids belonging to the family Amphinomidae.
Eurythoe is a genus of polychaetes belonging to the family Amphinomidae.
superseded combination, when a species was moved to a different genus in the years following its original description and naming
Soon thereafter, Brünnich (1772) introduced the genus Tapirus and the valid name for the Brazilian tapir is since the Tapirus terrestris and Linnaeus' original binomen (H. terrestris) is reduced to a superseded combination (a combination of the same specific epithet—terrestris, in this case—with the name of a genus to which the species is no longer referred).
new combination (combinatio nova). A new name for a taxon below the rank of genus based on a legitimate, previously published name, which is its basionym and which provides the final epithet of the new combination (Art. 6.10 and 7.3)
basionym. The legitimate, previously published name on which a new combination or name at new rank is based. The basionym does not itself have a basionym; it provides the final epithet, name, or stem of the new combination or name at new rank (Art. 6.10)
new combination. The first combination of a generic name and a previously established species-group name.
