Abstract. Coronaviruses are highly virulent and therefore important human and veterinary pathogens worldwide. This study presents the first natural hierarchical classification of Coronaviridae. We also demonstrate a “one-step” solution to incorporate the principles of binomial (binary) nomenclature into taxonomy of Coronaviridae. We strongly support the complete rejection of the non-taxonomic category “virus” in any future taxonomic study in virology. This will aid future recognition of numerous virus species, particularly in the currently monotypic subgenus Sarbecovirus. Commenting on the nature of SARS-CoV-2, the authors emphasize that no member of the Sarbecovirus clade is an ancestor of this virus, and humans are the only natural known host. 


Key words: Coronaviridae, cladistics, rooted phylogenetic trees, taxonomy, binary nomenclature, generic circumscription, SARS-CoV-2.
