variant name is a combination of three genus names followed by a specific adjective, the abbreviation "subsp". (Subspecies), and finally the adjective of the subspecies.
How do you classify variants? The widely accepted definition of the
variant is that of Mayr and Ashlock (1991: 43).
What are the rules for naming species?
Species are always identified by both common name and species name when writing down. In Homo sapiens, Homo is a genus and Sapiens is a species. When naming a new species, you need to identify the genus to which it belongs and why. You can then add the species name.
What is the variant based on?
Some species have no or at least two variants, but some (or all) variants may already be extinct. Subspecies are usually defined based on morphological differences between populations. The population should occupy a clear breeding range.
Why do some species have three names?
Some species are further subspecies, so they are also known by their three-part name. (To be truly capricious here, modern living humans are classified as Homo sapiens sapiens.) For some animals, the names of the genera, species, and subspecies are all the same-triplet!
