Phylum: Pisuviricota
Class: Pisoniviricetes

Pisoniviricetes is a class of positive-strand RNA viruses which infect eukaryotes.[1][2] A characteristic of the group is a conserved 3C-like protease from the PA clan of proteases for processing the translated polyprotein.[3][4][5] The name of the group is a portmanteau of member orders "picornavirales, sobelivirales, nidovirales" and -viricetes which is the suffix for a virus class.[6]
