A species description is a formal description of a newly discovered
species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ...

and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth.


Naming process

A name of a new species becomes valid (

in zoological terminology) with the date of publication of its formal scientific description. Once the scientist has performed the necessary research to determine that the discovered organism represents a new species, the scientific results are summarized in a scientific manuscript, either as part of a book or as a paper to be submitted to a scientific journal. A scientific species description must fulfill several formal criteria specified by the
nomenclature codes 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 specie ...

. These criteria are intended to ensure that the species name is clear and unambiguous, for example, the

Once the manuscript has been accepted for publication,One example of an abstract of an article naming a new species can be found at the new species name is officially created. Once a species name has been assigned and approved, it can generally not be changed except in the case of error. For example, a species of beetle (''

in 1933 when he had recently become chancellor of Germany. It is not clear whether such a dedication would be considered acceptable or appropriate today, but the name remains in use. Species names have been chosen on many different bases. The most common is a naming for the species' external appearance, its origin, or the species name is a dedication to a certain person. Examples would include a bat species named for the two stripes on its back (''

Species names recognizing benefactors

Species have frequently been named by scientists in recognition of supporters and benefactors. For example, the genus ''

of Great Britain. More recently, a species of lemur ('' Avahi cleesei'') was named after the actor John Cleese in recognition of his work to publicize the plight of lemurs in Madagascar. Non-profit ecological organizations may also allow benefactors to name new species in exchange for financial support for taxonomic research and nature conservation. A German non-profit organisation, BIOPAT – Patrons for Biodiversity, has raised more than $450,000 for research and conservation through sponsorship of over 100 species using this model. An individual example of this system is the ''

History of species descriptions

Early biologists often published entire volumes or multiple-volume works of descriptions in an attempt to catalog all known species. These catalogs typically featured extensive descriptions of each species and were often illustrated upon reprinting. The first of these large catalogs was

system beginning with his '' Systema Naturae'' in 1735. As the catalog of known species was increasing rapidly, it became impractical to maintain a single work documenting every species. Publishing a paper documenting a single species was much faster and could be done by scientists with less broadened scopes of study. For example, a scientist who discovered a new species of insect would not need to understand plants, or frogs, or even insects which did not resemble the species, but would only need to understand closely related insects.

. Very detailed formal descriptions are made by scientists, who usually study the organism closely for a considerable time. A diagnosis may be used instead of, or as well as the description. A diagnosis specifies the distinction between the new species and other species, and it does not necessarily have to be based on morphology. In recent times, new species descriptions have been made without voucher specimens, and this has been controversial.Kannan, Ragupathy (2007).
