Abstract

We provide comments and suggestions on the first eight “significant challenges” for zoological nomenclature listed by the International Commission on Zoological Nomenclature in 2024. In particular, we express disagreements regarding six of them, dealing with the term parataxon and related ones, the concept of hemihomonymy, the term polynomen, the Principle of Zoological Independence, differentiation of zoological nomenclature and the pronounciation of nomina. This analysis allows to survey and discuss several basic concepts and terms of zoological nomenclature.
