Type Species

In biological nomenclature, a type species is the species to which the name of a genus is permanently linked; it is the species that contains the biological type specimen(s) of the taxon. A type species is both a concept and a practical system which is used in the classification and nomenclature (naming) of animals and plants. The value of a "type species" lies in the fact that it makes clear what is meant by a particular genus name. This is an important concept whenever a taxon containing multiple species must be divided into more than one genus; the type species automatically assigns the name of the original taxon to one of the resulting new taxa, thus reducing the potential for confusion.

Under both the zoological and botanical nomenclature codes, every named genus or subdivision of a genus, whether or not currently recognized as valid or correct, should have a type species. In practice however there is a backlog of untypified names.

A similar concept is used for suprageneric groups, the concept of a type genus.

    Both classically- and romantically-minded spirits—inasmuch as these two species always exist—occupy themselves with a vision of the future: but the former do so out of a strength of their age, the latter out of its weakness.
    Friedrich Nietzsche (1844–1900)

    Chicago—is—oh well a façade of skyscrapers facing a lake, and behind the façade every type of dubiousness.
