Elucidating Article 45.6 of the International Code of Zoological Nomenclature: A dichotomous key for the determination of subspecific or infrasubspecific rank
Lingafelter, Steven W. and Nearns, Eugenio H. 2013. "Elucidating Article 45.6 of the International Code of Zoological Nomenclature: A dichotomous key for the determination of subspecific or infrasubspecific rank." Zootaxa, 3709, (6) 597–600. https://doi.org/10.11646/zootaxa.3709.6.9.
We present an overview of the difficulties sometimes encountered when determining whether a published name following a binomen is available or infrasubspecific and unavailable, following Article 45.6 of the International Code of Zoological Nomenclature (ICZN, 1999). We propose a dichotomous key that facilitates this determination and as a preferable method, given the convoluted and subordinate discussion, exceptions, and qualifications laid out in ICZN (1999: 49-50). Examples and citations are provided for each case one can encounter while making this assessment of availability status of names following the binomen.
