Tautonymy

From Freepedia

Tautonymy is a term in zoological nomenclature, meaning that the name of a genus is repeated as the "species name" or "subspecies name", for example: Natrix natrix (Linnaeus, 1758), the grass snake or Gorilla gorilla gorilla (Savage, 1847), the Western Lowland Gorilla. In zoological nomenclature this is quite allowed.

Note that botanical nomenclature differs slightly from this: to begin with it does not use the term "tautonymy", although it does use "tautonym".
