Emendation (zoology)

Last updated

In zoological nomenclature, emendations are intentional alterations made to the spelling of taxon names. In bacteriological nomenclature, emendations are made to the circumscription of a taxon. [1]

Contents

All emendations are considered by default to be available names. An emendation may be "justified" (when the original spelling is demonstrably incorrect under the International Code of Zoological Nomenclature, [2] Article 32.5), [3] or it may be "unjustified" (if the change violates the rules of the Code). [2] [lower-alpha 1] A justified emendation is different from a "mandatory change" only in that the latter is required by the Code, under Article 34. [2] [lower-alpha 2] An unjustified emendation is different from an "incorrect subsequent spelling" in that the latter is an unintentional change, while an emendation is explicitly intentional, and in that an incorrect subsequent spelling is not automatically considered to be an available name. [2] [lower-alpha 3]

Definition and circumscription in the Code

Under Article 33.2, any "demonstrably intentional change in the original spelling of a name" other than a mandatory change is considered an emendation. [2] [lower-alpha 4]

Under Article 33.2.1, the change must be made along with justification for altering the spelling, with both the original and the new spelling cited together. [2] [lower-alpha 5]

Under Article 33.2.2, if the justification provided complies with the conditions given in Article 32.5 (which define when an original spelling should be considered "incorrect"), then the emendation is defined as "justified". A justified emendation changes the spelling without changing the original attribution of authorship or date (the author of the emended spelling is not included in the attribution in any way). [2] [lower-alpha 6]

Under Article 33.2.3, any change that does not comply with Article 32.5 is unjustified. An unjustified emendation has its own authorship or date (the author of the original spelling is not included in the attribution in any way). [2] [lower-alpha 7]

Under Article 33.2.3.1, if an unjustified emendation has erroneously been treated as if it had been justified, and used as the valid spelling of a taxon name by the majority of authors, then it is reclassified as a justified emendation and treated as such in perpetuity. [2] [lower-alpha 8]

The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its publisher, the International Commission on Zoological Nomenclature. The rules principally regulate:

<span class="mw-page-title-main">Holotype</span> Example of an organism used to describe its species

A holotype is a single physical example of an organism used when the species was formally described. It is either the single such physical example or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept.

In biology, within the science of scientific nomenclature, i.e. the naming of organisms, an orthographical variant in botany or an orthographic error in zoology, is a spelling mistake, typing mistake or writing mistake within a scientific publication that resulted in a somewhat different name being accidentally used for an already-named organism. The rules that govern what to do when this happens are laid out in the relevant codes of nomenclature.

Nomenclature codes or codes of nomenclature are the various rulebooks that govern biological taxonomic nomenclature, each in their own broad field of organisms. To an end-user who only deals with names of species, with some awareness that species are assignable to genera, families, and other taxa of higher ranks, it may not be noticeable that there is more than one code, but beyond this basic level these are rather different in the way they work.

In zoological nomenclature, author citation refers to listing the person who first makes a scientific name of a taxon available. This is done in scientific work while fulfilling the formal requirements under the International Code of Zoological Nomenclature. According to Article 51.1 of the Code, "The name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable." However, recommendation 51A suggests, "The original author and date of a name should be cited at least once in each work dealing with the taxon denoted by that name. This is especially important and has a unique character between homonyms and in identifying species-group names which are not in their native combinations". For the sake of information retrieval, the author citation and year appended to the scientific name, e.g. genus-species-author-year, genus-author-year, family-author-year, etc., is often considered a "de-facto" unique identifier, although this usage may often be imperfect.

In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the International Code of Nomenclature for algae, fungi, and plants (ICN). In cases where a species is no longer in its original generic placement, both the authority for the original genus placement and that for the new combination are given.

<span class="mw-page-title-main">Uta Hick's bearded saki</span> Species of New World monkey

Uta Hick's bearded saki is an endangered species of bearded saki, a type of New World monkey. It is endemic to Brazil, where restricted to the Amazon between the Xingu and Tocantins Rivers. It was formerly treated as a subspecies of the more easterly C. satanas, but its back is pale brownish.

In zoological nomenclature, the valid name of a taxon is the correct scientific name for that taxon. The valid name must be used for that taxon, regardless of any other name that may currently be used for that taxon, or may previously have been used. A name can only be valid when it is an available name under the International Code of Zoological Nomenclature (ICZN); if a name is unavailable, then it cannot be considered either valid or invalid.

In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon.

<span class="mw-page-title-main">Conserved name</span> Conserved name (a protected scientific name)

A conserved name or nomen conservandum is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. Nomen conservandum is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the International Code of Nomenclature for Algae, Fungi, and Plants (ICN), while the International Code of Zoological Nomenclature favours the term "conserved name".

The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently.

Christie's long-eared bat, also known as the Egyptian long-eared bat, Christie's big-eared bat, or gray long-eared bat, is a species of vesper bat in the family Vespertilionidae. It is known from North Africa and the Middle East. Its natural habitats are subtropical or tropical dry shrubland, rocky areas, and hot deserts.

<i>Africofusus ocelliferus</i> Species of gastropod

Africofusus ocelliferus, common name the long-siphoned whelk, is a species of sea snail, a marine gastropod mollusk in the family Fasciolariidae, the spindle snails, the tulip snails and their allies.

AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature can be difficult for researchers who need the old sources for their taxonomic research.

In zoological nomenclature, an incorrect subsequent spelling is a name whose spelling has been unjustifiably and unintentionally changed from the original. It is distinct from a "mandatory change", a change to the original spelling that is required by the International Code of Zoological Nomenclature, and an "emendation", an intentional change to a name that may or may not be justified.

<span class="mw-page-title-main">Glossary of scientific naming</span> List of terms and symbols used in scientific names for organisms, and in describing the names.

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.

In botanical nomenclature, a validly published name is a name that meets the requirements in the International Code of Nomenclature for algae, fungi, and plants for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ICN as "designations".

Hotarionomus blattoides is a species of beetle in the family Cerambycidae. It was described by Francis Polkinghorne Pascoe in 1856, originally under the genus Monohammus. It is known from Malaysia and Indonesia.

Spintharus rallorum is a species of comb-footed spider in the family Theridiidae. It is found in Puerto Rico and Saint Kitts and Nevis. It is one of 15 new species described in 2018. The authors spelt the name as Spintharus ralli, but noted that it honoured the "grandparents of the first author of the species." As the name refers to more than one person, the World Spider Catalog changed it from the Latin genitive singular to the genitive plural.
