Parnaby, Harry, Ingleby, Sandy & Divljan, Anja, 2015, Taxonomic status of Podabrus albocaudatus Krefft, 1872 and declaration of Sminthopsis granulipes Troughton, 1932 (Marsupialia: Dasyuridae) as a protected name for the White-tailed Dunnart from Western Australia, Zootaxa 3904 (2), pp. 283-292 : 286

Podabrus albocaudatus Krefft, 1872 , a nomen oblitum

The Principle of Priority, as set out in Article 23.1 of the Code, states that the valid name of a taxon is the oldest available name applied to it. However, some circumstances call for a reversal of precedence (Article 23.9) to ensure stability of nomenclature if a junior synonym is in long established use, provided both conditions of Article 23.9.1 apply. These are: 1, the senior synonym has not been used as a valid name after 1899 (Article 23.9.1.1); and 2, the junior synonym has been used for a particular taxon, as its presumed valid name, in “at least 25 works, published by at least 10 authors in the immediately preceding 50 years and encompassing a span of not less than 10 years” (Article 23.9.1.2). Accordingly, we declare Sminthopsis granulipes Troughton, 1932 as a nomen protectum, and Podabrus albocaudatus Krefft, 1872 as a nomen oblitum, in accordance with Article 23.9.1. and as required by Article 23.9.2. of the Code. The Principle of Priority is reversed to maintain prevailing use of the junior synonym granulipes Troughton, 1932 instead of Podabrus albocaudatus Krefft, 1872 which must not be used as a replacement name, because both conditions of Article 23.9.1. are met. First, albocaudatus Krefft, 1872 has not, to our knowledge, been used as a valid name after 1899, thereby fulfilling the condition of Article 23.9.1.1. Second, the condition of Article 23.9.1.2 also applies because granulipes Troughton, 1932 has been used as a valid name in at least 25 works by ten or more authors over the past 50 years. Article 23.9.2 stipulates that a declaration of a junior synonym as a nomen protectum requires evidence that the condition of 23.9.1.2 applies. Accordingly, the Appendix lists 25 works published by more than ten authors over the past 50 years, all of which use S. granulipes Troughton, 1932 as a valid name.
