Introduction

The phylum Negarnaviricota was established in 2019 by the International Committee on Taxonomy of Viruses (ICTV) for negative-sense RNA viruses that can be connected evolutionarily through the possession of virally encoded RNA-directed RNA polymerases (RdRps). The phylum includes two subphyla, Haploviricotina and Polyploviricotina, for negative-sense RNA viruses that encode RdRps with or without mRNA capping activity, respectively. The two subphyla include four classes (Chunqiuviricetes, Milneviricetes, Monjiviricetes, and Yunchangviricetes) and two classes (Ellioviricetes and Insthoviricetes), respectively [33, 59, 74]. The phylum was last amended/emended in 2021 [34]. Here, we present the changes that were proposed to the phylum via official taxonomic proposals (TaxoProps) in 2021 and accepted by the ICTV in March and May 2022 [23, 70]. These changes are now part of the official ICTV taxonomy [24].
