The family Rhabdoviridae includes viruses with a negative-sense RNA genome. This family is divided into four subfamilies, and until recently, the subfamily Betarhabdovirinae, encompassing all plant-associated rhabdoviruses, was further divided into six genera. Here, we report the creation of two new genera within the subfamily Betarhabdovirinae - Alphagymnorhavirus and Betagymnorhavirus - to include recently described gymnosperm-associated viruses. The genus Alphagymnorhavirus includes nine species, while the genus Betagymnorhavirus includes only one species. Phylogenetic analysis indicated that these viruses form two well-supported clades that are clustered with the varicosaviruses, which have bisegmented genomes. In contrast, the 10 viruses included in the newly created genera have the distinctive feature that they have an unsegmented genome encoding five or six proteins. The creation of the genera Alphagymnorhavirus and Betagymnorhavirus has been ratified by the International Committee on Taxonomy of Viruses (ICTV).

Two novel members of the subfamily , family were identified in Brazil. Overall, their genomes have the typical organization 3'-' observed in mono-segmented plant-infecting rhabdoviruses. In aristolochia-associated cytorhabdovirus (AaCV), found in the liana aristolochia ( Hook), an additional short orphan ORF encoding a transmembrane helix was detected between and .

The is a large family of negative-sense (-) RNA viruses that includes important pathogens of ray-finned fish and marine mammals. As for all viruses, the taxonomic assignment of rhabdoviruses occurs through a process implemented by the International Committee on Taxonomy of Viruses (ICTV). A recent revision of taxonomy conducted in conjunction with the ICTV Study Group has resulted in the establishment of three new subfamilies (, , and ) within the , as well as three new genera (, , and ) and seven new species for viruses infecting fish or marine mammals.

Article Synopsis
- - In March 2021, the ICTV updated the phylum Negarnaviricota by officially ratifying new taxonomy changes.
- - The revision included the addition of four families, three subfamilies, 42 genera, and 200 species, along with several renaming and abolishing of species.
- - This article outlines the newly accepted taxonomic structure of Negarnaviricota following the ICTV's decisions.
