The term endemic is used about a taxon (species/genus/family/order) which occurs in only a single country or part thereof.

A taxon is also considered endemic if its distribution is restricted to one of the following regions: Borneo (incl. satellites), Comoro Archipelago, Grenadines, Hispaniola (incl. satellites), Mascarenes, New Guinea (incl. minor satellites), Saint Martin, Samoan Archipelago, Solomon Archipelago, Tierra del Fuego, or Timor, since these islands and archipelagos are biogeographic units, although they each cover areas belonging to two or three different countries.

A near-endemic taxon is also considered endemic herein, when the distribution includes only minor satellite islands off larger islands.

A taxon is considered endemic, even if its occurrence is expected (but unconfirmed) in neigbouring countries.

A taxon, which has been introduced to other countries, is still considered endemic, if its native distribution is restricted as described above.
