Subspecies

Definition

A taxonomic rank below species, typically a population of a species that shows distinct morphological or genetic differences from other populations, but that can still interbreed with them.

Etymology

From Latin 'sub', meaning 'under' or 'below', and 'species', meaning 'a kind, sort'.

Example

The monarch butterfly, Danaus plexippus, has several subspecies that are geographically and morphologically distinct.

Usage Notes

Subspecies are often classified based on variations that are significant but do not warrant the assignment of a new species status. The trinomial nomenclature is used in naming them (e.g., Panthera leo persica for the Asiatic lion subspecies).
