In publications dealing with the taxonomy and nomenclature of organisms, it may be desirable to cite the name of the author(s) who established the name concerned and the year of its establishment. For author citation, the rules of the relevant special Code apply, in addition to the provisions in the present Article.
When a name of a taxon is jointly authored by two persons, both author names are cited, linked with an ampersand (&) or the word “et”. When a name of a taxon has three or more authors, in subsequent citations only the first needs to be cited, followed by the phrase “& al.” (or et al.).
When a taxon of rank lower than progenus is altered in rank, or when its epithet is transferred to another genus or species, the names of the authors of the basionym (name- or
epithet-bringing acceptable name), and optionally its year, are placed in parentheses. After the parenthesis, the authorship and year of the alteration or transfer may be added.
Inclusion of the name of persons other than the actual author or authors, linked to the latter by the particle “ex”, is provided for in the Special Codes. As the prescribed order of names differs between the Codes, so that confusion may result, this practice is discouraged under the BioCode.
Author citations should be used sparingly in publications dealing with the taxonomy and nomenclature of organisms, and should be omitted in other publications unless they are necessary to avoid confusion.
