Subspecies:

When CITES protects a species, all subspecies which belong to that species are also protected.
The Convention can also protect a single subspecies or even a particular geographically separate population of that species.

Rollover the words subspecies and geographically separate population for a full definition.

For example:
Genus Species Subspecies
Amazona autumnalis autumnalis
Amazona autumnalis lilacina

Occasionally, you will see the abbreviations 'ssp.' or 'sspp.' next to the names. The abbreviation "ssp." is used to denote one subspecies and "sspp." to denote all subspecies.
