## Abstract

RNA viruses are ubiquitous in the environment and are important pathogens of humans, animals and plants. In 2024, the International Committee on Taxonomy of Viruses Animal dsRNA and ssRNA(-) Viruses Subcommittee submitted 18 taxonomic proposals for consideration. These proposals expanded the known virosphere by classifying 9 new genera and 88 species for newly detected virus genomes. Of note, newly established species expand the large family of *Rhabdoviridae* to 580 species. A new species in the family *Arenaviridae* includes a virus detected in Antarctic fish with a unique split nucleoprotein ORF. Additionally, four new species were established for historically isolated viruses with previously unsequenced genomes. Furthermore, three species were abolished due to incomplete genome sequence information, and one family was moved from being unasigned in the phylum *Negarnaviricota* into a subphylum and order. Herein, we summarize the 18 ratified taxonomic proposals and the general features of the current taxonomy, thereby supporting public and animal health responses.

## INTRODUCTION

RNA viruses are widely distributed and infect a broad variety of hosts. As technological advancements in high-throughput sequencing and data analysis have exponentially expanded in the twenty-first century, so has the RNA virome [1]. The International Committee on Taxonomy of Viruses (ICTV) Animal dsRNA and ssRNA(-) Viruses Subcommittee (SC) was established in 2014 to develop a taxonomy for RNA viruses detected in the kingdom Animalia. Study Groups within the Subcommittee are responsible for many viral families in the phyla *Negarnaviricota* (orders: *Muvirales, Jingchuvirales, Mononegavirales, Goujianvirales, Elliovirales, Hareavirales and Articulavirales) and *Duplornaviricota* (orders: *Reovirales and Ghabrivirales*) and the realm *Ribozyviria*.

The phylum *Negarnaviricota*, the largest taxon falling within the SC's remit, comprises viruses that predominantly have ssRNA(-) genomes, though some have an ambisense coding arrangement. Animal viruses assigned to this phylum exhibit a diversity of genome organizations (e.g. non-segmented or containing two to eight segments, linear or circular); however, all viruses within

this phylum encode homologous RNA-directed RNA polymerases (RdRP) that form a strongly supported clade in the RdRP phylogenetic tree of the kingdom *Orthornavirae* [2]. The subphylum *Haploviricotina* is distinguished by viruses that encode an RdRP with mRNA capping activity [3]. Families such as *Artoviridae*, *Bornaviridae*, *Filoviridae*, *Lispiviridae* and *Rhabdoviridae* are classified within this subphylum in the order *Mononegavirales*. Families such as *Hantaviridae*, *Peribunyaviridae*, *Phasmaviridae*, *Arenaviridae* and *Leishbuviridae* are classified in the subphylum *Polyploviricotina*, distinguished by viruses that have an RdRP with cap-snatching activity [3] and include the orders *Elliovirales*, *Hareavirales* and *Articulavirales*.

*Tosoviridae* includes a single species for a virus isolated from sea turtles [4]. This virus has a bi-segmented ssRNA(−) genome similar to certain polyploviricotines. However, phylogenetic analysis cannot definitively place this family in a subphylum, and so it is classified as an unassigned negarnaviricot.

The phylum *Duplornaviricota* includes viruses that possess dsRNA genomes and can be further characterized by the presence of an unusual T=1 capsid [5]. Viruses in this phylum that infect animals have genomes that are either non-segmented or have 9 to 12 segments. Viruses of the family *Sedoreoviridae* (order: *Reovirales*) have genomes of 10–12 dsRNA segments and virions that have a characteristic ‘smooth’ appearance [6] in contrast to viruses in the reoviral family, *Spinareoviridae*.

This summary includes the ratified taxonomic proposals from 2024 for the Animal dsRNA and ssRNA(−) Viruses SC and is not a comprehensive summary of all taxonomy proposals for dsRNA and ssRNA(−) viruses since some are covered by the Plant Viruses SC [7] and Fungal and Protist Viruses SC [8].

## Summary

### Taxonomic rank(s) affected

Genus and species (*Mononegavirales: Rhabdoviridae: Alpharhabdovirinae*)

### Description of current taxonomy

The subfamily *Alpharhabdovirinae* currently comprises 33 genera and 235 species.

### Proposed taxonomic change(s)
Create nine new species in six existing genera (*Alphapaprhavirus*, *Sigmavirus*, *Merhavirus*, *Tupavirus*, *Alphanemrhavirus* and *Alpharicinrhavirus*) for viruses recently detected in bats, shrew or various invertebrates by metagenomic sequencing. Rename the existing genus *Thriprhavirus* (as *Alphathriprhavirus*), and create a new genus *Betathriprhavirus* including two new species for viruses detected in thrips by metagenomic sequencing.

**Justification**

The viruses cluster phylogenetically with others in the existing or proposed genera in maximum likelihood trees inferred using L protein sequences. All new species in existing genera meet established demarcation criteria. The proposed renamed and new genera for viruses detected in thrips are well-separated phylogenetically.

### Summary

**Taxonomic rank(s) affected**

*Cardoreovirus* genus

**Description of current taxonomy**

The genus *Cardoreovirus* currently has only one species, *Cardoreovirus eriocheiris*, whose exemplar member is Eriocheir sinensis reovirus (EsRV).

**Proposed taxonomic change(s)**

A new species (*Cardoreovirus callinectes*) belonging to the *Cardoreovirus* genus should be established.

**Justification**

The exemplar virus (*Callinectes sapidus* reovirus 2, *CsRV2*) of the proposed new species – *Cardoreovirus callinectes* – exhibits amino acid sequence similarities ranging from 46 to 79% for segments 1–12 compared to *EsRV* in the established species *Cardoreovirus eriocheiris*.

### Summary

**Taxonomic rank(s) affected**

*Hareavirales: Arenaviridae: Mammarenavirus*

**Description of current taxonomy**

Eleven genomes representing four species within American mammarenavirus clade C were present in public records. An additional 13 clade C mammarenavirus genomes were added to public records following the sequencing of mammarenavirus-positive rodent samples collected in Argentina from 1990 to 2020.

**Proposed taxonomic change(s)**

Establishment of one new species in genus *Mammarenavirus* for a virus named vello virus, identified following the sequencing of mammarenavirus-positive rodent samples collected in Argentina from 1990 to 2020.

**Justification**

Two of the L segment sequences of 13 clade C mammarenavirus genomes identified following the sequencing of mammarenavirus-positive rodent samples collected in Argentina from 1990 to 2020, meet current demarcation species criteria for the genus *Mammarenavirus*. We propose the two isolates described by Shedroff *et al.* [9] to represent a virus named ‘vello virus’ and to assign this virus to a new species, *Mammarenavirus vello*.

**Proposed taxonomic change(s)**

Addition of one new species

**Justification**

Using a coding-complete genome sequence comprising all three genomic segments, we demonstrate that a virus (Ozark virus, OZAV) discovered in hispid cotton rats (*Sigmodon hispidus* Say and Ord, 1825) sampled in the Ozark Plateau, Arkansas, USA, is a genetically distinct orthohantavirus.

**Title:** Create four new species, abolish three species, and rename two species in the family *Phasmaviridae*

**Authors:** Ballinger MJ (ballinger@biology.msstate.edu), Junglen S, De Coninck L

### Summary

**Taxonomic rank(s) affected**

Species

**Description of current taxonomy**

The family *Phasmaviridae* includes 29 species organized across 7 genera.

**Proposed taxonomic change(s)**

Create four new species, abolish three species established previously, and rename two species established previously.

**Justification**

Coding-complete virus genome sequences are available to justify the creation of four new species. Each exhibit 1% L protein amino acid sequence identity to other exemplar viruses in the family *Phasmaviridae*. Three species were previously established in error due to an oversight; the available genomes are not coding-complete. Two previously established species epithets erroneously referred to places and are renamed here using appropriate suffixes.

### Summary

**Taxonomic rank(s) affected**

Genus and species (*Mononegavirales: Rhabdoviridae*)

**Description of current taxonomy**

The family *Rhabdoviridae* currently comprises four subfamilies and one genus (*Platrhavirus*) unassigned to a subfamily that includes six species.

**Proposed taxonomic change(s)**

Rename the existing genus *Platrhavirus* (as *Alphaplatrhavirus*) and create 12 new species in the renamed genus, and create 2 new genera (*Betaplatrhavirus* and *Gammaplatrhavirus*) including 18 new species for viruses detected by metagenomic sequencing in cestode or trematode worms (Platyhelminthes) or in the faeces or visceral organs of animals (mammals, fish or crustaceans) that appear to have been infested with worms.

**Justification**

The viruses cluster phylogenetically with others in the existing or proposed genera in ML trees inferred using L protein sequences. All new species in existing genera meet established demarcation criteria. Members of the proposed renamed and new genera for viruses are well-separated phylogenetically from each other and other rhabdoviruses.

**Title:** Create two new species (*Rotavirus kappagastroenteritidis*, *Rotavirus lambdagastroenteritidis*) in the genus *Rotavirus* (family *Sedoreoviridae*)

**Author:** John R (Reimar.Johne@bfr.bund.de)

### Summary

**Taxonomic rank(s) affected**

The genus *Rotavirus*

**Description of current taxonomy**

Currently, the genus *Rotavirus* includes nine different rotavirus species.

**Proposed taxonomic change(s)**

Two new rotavirus species (*Rotavirus kappagastroenteritidis* and *Rotavirus lambdagastroenteritidis*) should be created.

**Justification**

Evolutionary analysis of complete coding regions of the novel rotavirus genomes (rotavirus K for *Rotavirus kappagastroenteritidis* and rotavirus L for *Rotavirus lambdagastroenteritidis*) indicates a separate branching on phylogenetic trees of all genome segments from those of established rotavirus species. In addition, the maximum identities of their deduced VP6 amino acid sequences with those of established rotavirus species reference strains are 51% for rotavirus K and 47% for rotavirus L, which are lower than the cut-off value (53%) for the definition of new *Rotavirus* species.

**Title:** Create one new genus (*Crabreovirus*) with three new species

**Authors:** Zhao M (mzhao@rvc.ac.uk), Schott E (schott@umces.edu)

### Summary

**Taxonomic rank(s) affected**

*Sedoreoviridae* family

**Description of current taxonomy**

*Sedoreoviridae* currently has six genera, namely *Cardoreovirus*, *Mimoreovirus*, *Orbivirus*, *Phytoreovirus*, *Rotavirus* and *Seadornavirus*.

**Proposed taxonomic change(s)**

A new genus, named *Crabreovirus*, should be established in the *Sedoreoviridae* family. This new genus should include three new species, including *Crabreovirus callinectes*, *Crabreovirus scylla* and *Crabreovirus eriocheiris*.

**Justification**

Three representative viruses of the proposed new *Crabreovirus* genus exhibit less than 20% amino acid sequence identity in VP1 when compared to virus members of other established genera within the *Sedoreoviridae* family. A maximum likelihood phylogenetic tree shows that viruses in the three proposed new species form a distinct clade from members of other *Sedoreoviridae* genera, yet remain within the same clade as each other. The phylogenetic analysis supports the classification of these three species into a new genus, *Crabreovirus*.
