Sorry, Hendrik:

Please read the Glossary in the ICZN.

"Unavaible name. A scientific name that does not conform to Articles 10 to
20, or that is an excluded name under Article 1.3."  [Yes, a name that is
not published (see below) is also technically unavailable]

"Nomen nudum .. A nomen nudum is not an available name. ..."

A scientific name that is in a work which is not published (conforms to
Art. 8-9) is simply an unpublished name.

See also the summary table after the glossary.

Dear colleague,

In my experience, the publication criteria that have to be met before a
name becomes available are very easy to meet. With respect to the concrete
cases you mention, and assuming that other criteria are fulfilled, I'd say
that names or nomenclatural acts published in any hobby-journal are
available, unless there is a statement disclaiming the publication or
name/act, or unless the work is suppressed. Coverage in Zool. Rec., ISSN,
storage in any library, and other content of the journal are of no real
relevance. It is hard to believe that any author, professional or not, would
publish a new name, in any journal or even by producing an independent
"publication" (there are examples of people who distributed sets of copied
pages, nicely provided with an official-looking frontage) without the
intention of providing a public and permanent scientific record, so art.
8.1.1. constitutes only a very weak filter. By the way, a nomen nudum is an
available name published without any description or indication. If the
criteria of publication or not met with, the name is unavailable.

Hope this helps,
