a taxonomic category of animals and plants below a species. A subspecies is a group of geographically or, less frequently, ecologically or geochronologically isolated populations of a species, in which all or the majority of individuals differ in one or more morphological characters from individuals of other populations of the same species.

The name of a subspecies is formed by adding a third word, or epithet, to the species name. For example, the Middle Asian fox Vulpes vulpes flavescens is a subspecies of the red fox (Vulpes vulpes). In botany and, sometimes, zoology, subsp. or ssp. is written between the species name and the name of the subspecies.


A geographically defined grouping of local populations which differs taxonomically from similar subdivisions of species.
