Patronym (taxonomy)

A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species which have been described previously, or are related. The species description often contains photographs or other illustrations of the type material and states in which museums it has been deposited. The publication in which the species is described gives the new species a formal scientific name. Today, some 1.9 million species have been described and named, out of some 8.7 million that may actually exist on Earth. Millions more have become extinct.

It is customary for scientists to introduce all relevant new findings and research in a scientific manuscript, which is sent to other scientists for peer review. If accepted, it is published in a scientific journal of the appropriate discipline or in a book. Descriptions and naming of a new species or other taxa follow the same process.

A name of a new species becomes valid (available 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, e.g. selection of at least one type specimen. These criteria are intended to ensure that the species name is clear and unambiguous, for example, the International Code of Zoological Nomenclature (ICZN) states that "Authors should exercise reasonable care and consideration in forming new names to ensure that they are chosen with their subsequent users in mind and that, as far as possible, they are appropriate, compact, euphonious, memorable, and do not cause offence."
