According to the qualifying conditions of the Code (Art. 75.3) a neotype should only be designated when there
is an exceptional need, and only when that need is stated expressly, and when the designation is published with a
number of particulars, including (Art. 75.3.1) a statement that the neotype is designated with the express purpose of
clarifying the taxonomic status or type locality of a nominal taxon. Such a statement is lacking in Pouyaud et al.
(2003). According to Art. 75.3.4, the authors’ reason for believing the name-bearing type specimen(s) to be lost or
destroyed, and the steps taken to trace it or them, must be stated with the designation. Pouyaud et al. (2003) give no
details on this point. Furthermore, Art. 75.3.5 requires evidence that the neotype is consistent with what is known
of the former name-bearing type from the original description and other sources.
