subspecies

subspecies Technically, a race of a species that is allocated a Latin name. The number of races recognized within a species and the allocation of names to them is somewhat arbitrary. Systematic and phenotypic variations do occur within species, but there are no clear rules for identifying them as races or subspecies except that they must be: (a) geographically distinct; (b) populations, not merely morphospecies; and (c) different to some degree from other geographic populations.
