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 many groups of organisms subspecies have been named on minor morphological differences which usually occur in different geographically defined populations. Often, for example in birds, different parts of a CLINE have been given subspecific status; if clines are to be named, only the extremes should have subspecific names. Clearly defined populations such as island forms often merit subspecific names and might be considered as species in the making. see ISOLATING MECHANISMS.See SUBSP subspecies
