Type species
Translation- Type species
In
taxonomy , a type species is the species that originally defined a genus. It is an individual specimen (either tangible, fossilized, or an illustration) that fixes the name of agenus (or of ataxon in a rank lower than genus). Two different definitions are used interchangeably, in a general term and abotanical term.General definition
Strictly speaking, a type species exists only in
zoological nomenclature . As set in article 42.3 of theInternational Code of Zoological Nomenclature , the type of the name of a genus or subgenus (a "genus-group name") is the "type species". This is defined as "The nominal species that is the name-bearing type of a nominal genus or subgenus". The species name in turn is fixed to a type specimen.Botanical definition
In
botanical nomenclature , the type of a name of a genus or species is a specimen (or illustration) ("ICBN", articles 10.1, 8.1 and 10.4). This type will usually be the type of an included species, in which case it can be indicated by the name of this species (Art 10.1). This species is called the "type species", but this phrase has no formal standing. The botanical type specimen itself is generally called a "type specimen."See also
