Related article in the ZooCode: 5.3. Typographical signs and qualifying abbreviations excluded. A typographical sign such as ?, and an abbreviation such as aff., prox. or cf., when used to qualify the application of a scientific name, does not form part of the name of a taxon even when inserted between the components of a name.
