16.4. Species-group names: fixation of name-bearing types to be explicit. Every new specific and subspecific name published after 1999, except a new replacement name (a
nomen novum), for which the name-bearing type of the nominal taxon it denotes is fixed automatically [Art. 72.7], must be accompanied in the original publication
16.4.1. by the explicit fixation of a holotype, or syntypes, for the nominal taxon [Arts. 72.2, 72.3, 73.1.1, 73.2 and Recs. 73A and 73C], and,
16.4.2. where the holotype or syntypes are extant specimens, by a statement of intent that they will be (or are) deposited in a collection and a statement indicating the name and location of that collection (see Recommendation 16C).
