Genus (biology)


July 5, 2022

Genus (Latin genus, plural genera) - the basic, obligatory systematic category covering a species or monophyletic group of species distinguished on the basis of one or more taxonomic features. Each taxa in the rank of genus is also used to define the name of the genus. The auxiliary categories for the genus are supergenus (supergenus) and subgenus (subgenus).

Scientific name of the genus

The rules for creating generic and species names are described in the International Codes of Botanical, Zoological and Bacterial Nomenclature. The genus is given a unique and uninominal (single) name that is part of the binomial (two-part) species name and the trinominal (three-part) name of the subspecies. The gender name is a noun in the nominative singular, derived from Greek, Latin, or Latinization from another language. It has a specific gender - masculine, feminine, or neuter - depending on the word from which the name is derived. The scientific name of a genus is always written in a capital letter and in a typeface that distinguishes it from the rest of the text, and is identical to the genre epithet if it is included in the species name. For example: The bird of the species Cardinalis cardinalis is a well-known cardinal. A bird of the species Cardinalis cardinalisto well known cardinal. The bird of the species Cardinalis cardinalis is a well-known cardinal. The bird of the species Cardinalis cardinalis is a well-known cardinal. Italics are traditionally used in plain text (example 1).

The author of the generic name

The name of the author is given after the name and - separated by a comma - the date of first publication, eg Cardinalis Bonaparte, 1838.

Nomenclature types

The nomenclatorical type of a genus is the typical species, i.e. the species on the basis of which a given genus was described, while the family is described based on the typical genus.

Taxonomic position

The family is the basic category that is higher than the genus, the species is the lower one. The position of the kind in the hierarchical system (including auxiliary categories) is as follows. family subfamily supergenus type subgenus species
