摘要

Typification, the linkage of a name-bearing “type” to a taxon and the description and deposition of a corresponding type specimen, has been a principle of biological taxonomy for over two centuries. It was introduced to promote nomenclatural uniformity and stability. Until recently, a modified form of typification was also written in the rules governing the taxonomy of viruses. However, in 2021, the International Committee on Taxonomy of Viruses abolished all type species and removed the requirement to designate a type species when a new genus is created. In this article, I briefly review the history of typification, explain its purpose and evaluate its relevance to current virological practice.
