Subgenus

Subgenus

In biology, a subgenus is a taxonomic rank directly below genus. See rank (botany) and rank (zoology).

In zoology, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic and specific name: e.g. the Tiger Cowry of the Indo-Pacific, "Cypraea (Cypraea) tigris" Linnaeus, which belongs to the subgenus "Cypraea" of the genus "Cypraea". However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name.
