Abstract

Our epoch is a crucial one for scientific knowledge of the organisms that live on our planet. The combination of the biodiversity crisis and the taxonomic gap results in taxonomic urgency. In this context, great attention should be paid to the nomenclatural rules helping taxonomists in their urgent task, rather than diverting their time and energy to secondary questions or debates. In zoology, the new criterion of ‘prevailing usage’, introduced in the 1999 edition of the Code of nomenclature to ‘protect’ some nomina, raises four kinds of problems: (1) it weakens the binding value and strength of the Code, thus indirectly bringing support to the development of alternative nomenclatural systems; (2) it encourages personal debates among taxonomists, giving undue importance to the ‘argument of authority’ in nomenclatural decisions; (3) it sends a wrong message to non-taxonomists as regards completion of the taxonomic work; (4) it acts as a threat against natural history museums, in devaluing onomatophores (type specimens), the conservation of which is one of their major ‘visible’ functions. In conclusion, it is suggested that ‘protection’ of some nomina ‘threatened’ by rules of the Code should be limited strictly to nomina well-known outside the small world of systematics. This would require new rules for the Code to clearly define categories of usage on the basis of objective criteria.
