Subsubspecies

[…]and any geographical sections of the whole which have been called by distinct names are, by definition, only subspecies, or even subsubspecies.

Kinsey’s species of Cynips are considered to be only subspecies or subsubspecies by Goldschmidt (282).

Cases may also be encountered where very distinct subspecies appear to have been further segregated into what might be equivalent to “subsubspecies.”

Moreover, a species usually encompasses subordinate classification groups such as subspecies (or varieties), subsubspecies (or races), and strains, and these too are distinguished by particular, unique variations (Fig. 16.2).
