Taxacom: nomen nudum and synonymy question

[John Grehan]

Thanks Doug and Adam for the latest comments. In my list I (and colleagues)
will generally not use abbreviations. As this article is purely digital
(and open access) there are no space constraints.

With respect to the definition (thanks) that "*synonym*, *n*. Each of two
or more names of the same rank used to denote the same taxonomic taxon." -
would I be correct to understand from this that an infrasubspecific name
such as an aberration cannot be considered a synonym?

With respect to:

Article 45.6.4. it is subspecific if first published before 1961 and its
author expressly used one of the terms ``variety" or "form" (including use
of the terms "var.", "forma", "v." and "f."), unless its author also
expressly gave it infrasubspecific rank, or the content of the work
unambiguously reveals that the name was proposed for an infrasubspecific
entity, in which case it is infrasubspecific (our emphasis).

I take that to mean that subspecific names (or inferred before 1961 by var
forma v and f) are considered to have the same rank as species and
therefore qualify as synonyms?

Sorry to gnaw over these details. Neve would have made a lawyer.
