What is "subspecific name"

n. (context zoology English) The third word in the scientific name of a subspecies, following the name of the species. This applies only to formal names of animals.

In zoological nomenclature, a subspecific name is the third part of a trinomen. In zoology there is only one rank below that of species, namely " subspecies".

The name of a subspecies is a trinomen, a trinomial name, i.e., a name that consists of three names: generic name, specific epithet, and subspecific epithet. The subspecific epithet is written like the specific epithet: without capitalisation but typeset in italics.
