In biology, a monotypic taxon is a taxonomic group which contains only one immediately subordinate taxon.[1]

A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. Although the phrase appears to indicate that a taxon has a single type specimen (with no syntypes, lectotypes, or other types), this is not the usage.

In the case of genera, the term "unispecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a special case where a genus and a single species are simultaneously described.[2]

Examples[edit]

Just as the term "monotypic" is used to describe a large taxon including only one subdivision, one can also refer to the contained taxon as monotypic within the larger taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are listed below.

In Botany, monotypic is more used than monospecific with the same meaning.
