**Abstract**

This article summarises the activities of the International Committee on Taxonomy of Viruses Bacterial Viruses Subcommittee, detailing developments in the classification of bacterial viruses. We provide here an overview of all new, abolished, moved and renamed taxa proposed in 2024, approved by the Executive Committee, and ratified by membership vote in 2025. Through the collective efforts of 74 international contributors of taxonomy proposals in this round, 43 ratified proposals have led to the creation of one new phylum, one class, four orders, 33 families, 14 subfamilies, 194 genera and 995 species. These proposals mark significant progress in refining the taxonomy of bacterial viruses. Key updates include the creation of new orders and families that include existing taxa to better reflect genomic and evolutionary relationships. As sequencing and bioinformatics approaches continue to advance, further expansion and refinements in viral taxonomy can be anticipated in the coming years.

## INTRODUCTION

The taxonomy of bacterial viruses has undergone significant changes in recent years, notably the abolishment of the paraphyletic families *Myoviridae*, *Siphoviridae* and *Podoviridae*, along with the order *Caudovirales* [1, 2]. This reorganization left a number of orphan subfamilies and genera within the class *Caudoviricetes* without a designated family or order. The adoption of genome-based classification, which focuses on reconstructing virus evolutionary histories through nucleotide and amino-acid sequence similarity, phylogenetic analysis of core genes and increasingly, of protein folds and motifs for the demarcation of higher ranks, has enabled the identification of many new monophyletic taxa [3]. Additionally, a number of tools are now available to aid the classification of bacterial viruses across different taxonomic ranks (e.g. [4–7]).

Here, we present summaries of all ratified taxonomic proposals submitted to the Bacterial Viruses Subcommittee of the International Committee on Taxonomy of Viruses (ICTV) in 2024. These proposals were assessed and approved at the ICTV Executive Committee meeting (EC56, July 2024) and ratified by membership vote in 2025. Full versions of the proposals summarized here,

as well as those from previous years, are available on the ICTV website (https://ictv.global/files/proposals/approved). A total of 43 proposals were ratified, leading to the creation of one new phylum, one class, four orders, 33 families, 14 subfamilies, 194 genera and 995 species (Table 1).

Notable highlights include the creation of the phylum *Artimaviricota* for a group of segmented RNA viruses predicted to infect thermophilic bacteria [8]. The Lak megaphages [9, 10] were assigned to the new order *Grandevirales*, while the family *Autographiviridae* was elevated to order (*Autographivirales*), containing four newly defined families. The new order *Pantevenvirales* encompasses the families *Straboviridae*, *Kyanoviridae*, and *Ackermannviridae*. Importantly, the creation of 30 new families continues the process of addressing floating taxa within the class *Caudoviricetes*. This class now contains 31 families assigned to 10 orders, with 70 families remaining unassigned to any order (Fig. 1).

The Bacterial Viruses Subcommittee has also seen growing engagement from the wider research community, as evidenced by an increased number of proposals originating from outside the Subcommittee and its Study Groups. This is encouraged, and we invite researchers to contact the Subcommittee and relevant Study Groups for guidance (https://ictv.global/study-groups?webform_submission_value_1=7). A file including all the Tables of taxonomic changes below is available as a supplementary file to this article.

**Title:** Create three new families (*Alisviridae*, *Ludisviridae* and *Nixviridae*) with seven new genera and 24 new species

**Authors:** Matrishin CB, Kauffman KM (kmkauffm@buffalo.edu)

**Summary**

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

The viruses classified in this proposal do not have a current taxonomic assignment.

**Proposed taxonomic change(s)**

Creation of three new families (*Alisviridae*, *Ludisviridae* and *Nixviridae*) with seven new genera (*Honmavirus*, *Ludisvirus*, *Dewhirstvirus*, *Nixvirus*, *Haasevirus*, *Excelsiorvirus* and *Schifferlevirus*) and 24 new species.

**Justification**

A comprehensive analysis of publicly available NCBI *Porphyromonas gingivalis* genomes revealed three new families of viruses, containing seven new genera and 24 new species. This discovery, using a rigorous, complementary bioinformatic approach, revealed what we believe to be precise nucleotide start and end points of the prophage genomes within bacterial contigs. These novel prophages represent the first systematically described phages of *P. gingivalis*. This work, including the proposed taxonomic classifications and figures shown in this proposal, is described in Matrishin *et al.* [11]. Phage genomes are available on NCBI within BioProject PRJNA874424.

## 2024.002B.Andersonviridae_1nf_2ng_98ns

**Title:** Create a new family, *Andersonviridae* for the FelixO1-like phages (class: *Caudoviricetes*)

**Authors:** Moraru C, Tolstoy I, Kropinski AM (Phage.Canada@gmail.com)

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

At present the following taxa exist as floating genera in the class *Caudoviricetes*: *Felixounavirus*, *Kolesnikvirus*, *Suspvirus* and *Mooglevirus*.

**Proposed taxonomic change(s)**

We propose the creation of one new family, *Andersonviridae*.

To update the genus *Felixounavirus* with 80 new species.

To update the genus *Mooglevirus* with 11 new species.

To add one new species to the genus *Kolesnikvirus*.

To create a new genus *Daniellevirus* with two species.

To create a new genus *Arnovirus* with three species.

**Justification**

We investigated the evolutionary relationships of 123 bacteriophages. Analysis of conserved genes revealed that these phages form a deeply branching monophyletic clade with a distance commensurate with the creation of a new family.

**Title:** Move newly classified viral genera into *Chimalliviridae* family and fix previous error

**Author:** Prichard A, Pogliano J (jpogliano@ucsd.edu)

### Summary

**Taxonomic rank(s) affected**

We propose to move fifteen genera into the *Chimalliviridae* family and remove one genus from this family.

**Description of current taxonomy**

Last year, we submitted a proposal to create a new viral family called *Chimalliviridae* and re-assigned currently classified viruses into this family. This proposal was accepted, but in the meantime, more viruses that belong in this family have been officially recognized and classified by the ICTV. Since these proposals were submitted in the same year as ours, and there was no existing family that was appropriate for them to be assigned to at the time, these viruses were not assigned to any viral families. However, we believe that these viruses belong to the now-recognized *Chimalliviridae* family.

**Proposed taxonomic change(s)**

Members of the newly created genera *Miamivirus*, *Nimduovirus*, *Meadowvirus*, *Branisovskavirus*, *Ferozepurvirus*, *Chaoshanvirus*, *Ludhianavirus*, *Siatvirus*, *Maaswegvirus*, *Eowynvirus*, *Miltoncavirus*, *Phabiovirus*, *Serwervirus*, *Tepukevirus* and *Pawinskivirus* should be added to the family *Chimalliviridae*. Additionally, the genus *Takahashivirus* should be removed from the family *Chimalliviridae*, as it was included in our proposal last year by mistake and should not belong to this family.

**Justification**

We have redone the phylogenetic analysis used to support the creation of the family *Chimalliviridae* but with the inclusion of several newly classified genera. This shows that these new genera belong in the family *Chimalliviridae*, while *Takahashivirus* PBS1, which we included by mistake, does not.

**Summary**

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

Three taxa of temperate *Streptomyces* phages exist as floating genera in the class *Caudoviricetes*, namely, *Vashvirus*, *Tigunavirus* and *Lomovskayavirus*. Up to the present, no effort has been made to assign them to higher taxa.

**Proposed taxonomic change(s)**

*Riboviria, Orthornavirae, Pisuviricota, Duplopiviricetes, Durnavirales.*

#### Description of current taxonomy

Order *Durnavirales* includes six families of viruses with double-stranded RNA genomes. Most of the durnavirals infect fungal hosts, with the exception of partitivirids, which besides fungi, infect plants and protozoa, and picobirnavirids, which appear to infect bacteria.

#### Proposed taxonomic change(s)

Create a new family, *Soropartiviridae*, with a genus, *Caliparnavirus*, within the order *Durnavirales* to classify partiti-like viruses discovered in the hot spring samples and infecting thermoacidophilic bacteria.

## 2024.014B.Grandevirales_1no_2nf_3nsf_4ng_8ns

**Title:** Create one new order *Grandevirales* (*Duplodnaviria*)

**Authors:** Cook R, Pye HV, Crisci MA, Telatin A, Santini JM (j.santini@ucl.ac.uk), Adriaenssens EM (Evelien.adriaenssens@quadram.ac.uk)

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

The viruses classified in this proposal do not have a current taxonomic assignment.

**Proposed taxonomic change(s)**

We propose the creation of one new order, *Grandevirales*, including two new families, *Lakviridae* and *Epsomviridae*, three sub-families (*Quingentivirinae*, *Quadringentisvirinae* and *Sescentorumvirinae*) and four genera (*Vetruvanivirus*, *Hatfieldvirus*, *Amboselivirus* and *Wendovervirus*). We also propose the creation of eight novel species within these genera.
## Justification

We investigated the evolutionary relationships of 23 megaphage genomes with sizes greater than 400 kb and propose a taxonomy for their classification. Analysis of their putative proteins revealed that Lak phages form a deeply branching monophyletic clade within the class *Caudoviricetes* apart from all other genomes, and hence justifies the creation of a new order *Grandevirales*. One of the interesting features of this clade is that all current members are characterized by an alternative genetic code, where the TAG stop codon is repurposed to encode an amino acid.

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

The viruses classified in this proposal do not have a current taxonomic assignment.

**Proposed taxonomic change(s)**

Caulobacter bacteriophage Kronos is a unique siphovirus with a 50 nm icosahedral head and a long (150 nm) flexible tail.

Aside from two phages, there are no close matches of its genome sequence to any other bacteriophage in the GenBank database.

Additional phages that are closely related to Kronos can be grouped into three distinct species based on the ICTV criteria.

**Justification**

The creation of the genus *Kronosvirus* complies with current demarcation criteria [2].

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

### Description of current taxonomy

PB1-like phages have been classified into the following genera: *Kylevirus*, *Tabernariusvirus*, *Bcepfunavirus*, *Pbunavirus*, *Wifcevirus*, *Myosmarvirus* and *Carpasinavirus*. All these are myoviruses infecting members of the Betaproteobacteria and Gammaproteobacteria.

### Proposed taxonomic change(s)

To create ten new species in the genus *Pbunavirus*.

To create one new species in the genus *Myosmarvirus*.

To add six new species to the genus *Wifcevirus*.

To add one new species to the genus *Carpasinavirus*.

To create a new single species genus *Gladiolivirus*.

To create a new single species genus *Irusalimvirus*.

To create a new single species genus *Plutovirus*.

To create a new family, *Lindbergviridae*, for the above-mentioned taxa as well as *Kylevirus*, *Tabernariusvirus* and *Bcepfunavirus*.

## Justification

All our genomic and proteomic analyses reveal that the previously established genera *Kylevirus* (2020.086B.R.Kylevirus), *Tabernariusvirus* (2018.099B.A.v1.Tabernariusvirus), *Bcepfunavirus* (2020.116B.R.Pbunavirus), *Pbunavirus*, *Wifcevirus*, *Myosmarvirus* and *Carpasinavirus* together with the three new genera listed above belong to a new family which we have named in honour of Alf A. Lindberg. The bacteriophages share 12 common proteins.

**Authors:** Wójcicki M (michal.wojcicki@hirszfeld.pl), Shymialevich D, Średnicka P, Gientka I, Błażejak S, Sokołowska B

### Summary

**Taxonomic rank(s) affected**

Proposal to create a new genus (*Kononvirus*) with a single species (tailed phages from class *Caudoviricetes*, family *Demerecviridae* and subfamily *Markadamsvirinae*).

**Description of current taxonomy**

In 2022, significant changes to the taxonomy of bacterial viruses were introduced: the paraphyletic morphological families *Podoviridae*, *Siphoviridae* and *Myoviridae* as well as the order *Caudovirales* were abolished, which is replaced by the class *Caudoviricetes* to group all tailed bacterial and archaeal viruses with icosahedral capsids and a double-stranded DNA genome. Moreover, a binomial system of nomenclature for species was implemented. Currently, the family *Demerecviridae* includes three subfamilies (*Ermolyevavirinae*, *Markadamsvirinae* and *Mccorquodalevirinae*) and six separate genera (*Keyvirus*, *Novosibvirus*, *Pogseptimavirus*, *Priunavirus*, *Shenzhenvirus* and *Sugarlandvirus*) not classified at the subfamily level. The subfamily *Markadamsvirinae* currently includes two genera: *Epseptimavirus* and *Tequintavirus*.

**Proposed taxonomic change(s)**

We performed genomic analysis of newly isolated Enterobacter phage KKP_3711. Genome and protein analyses suggest that this bacteriophage belongs to the subfamily *Markadamsvirinae*. Still, the differences are too great to assign it to one of the two genera within this subfamily. Therefore, we propose to create a new genus, *Kononvirus*, including a single species, *Kononvirus KKP3711*.

**Justification**

Based on DNA and protein similarity, this is a cohesive genus.

**Title:** To create one new species in the genus *Bifilivirus*, family *Paulinoviridae*

**Authors:** Deptula P (deptula@food.ku.dk), Sha Y, Potipimpanon S, Vogensen FK, Nielsen DS, Knezevic P

### Summary

**Taxonomic rank(s) affected**

This is a proposal for creating a new species within the genus *Bifilivirus*.

**Description of current taxonomy**

The genus *Bifilivirus* currently includes one species.

**Proposed taxonomic change(s)**

Addition of a new species *Bifilivirus philemonii*.

**Justification**

Filamentous phage Philemon was isolated from raw milk Emmental cheese on a dairy-associated strain of *Propionibacterium freudenreichii* PB4. The obtained TEM confirmed filamentous morphology. Philemon forms plaques on three *P. freudenreichii* strains in our collection, including the strain TL18, which was used for characterization of phage B5 (though no plaquing was reported for phage B5) [12]. The phage genome was sequenced with the Illumina platform after the formation of the complementary strand with the MDA technique. The genome is 5802 nucleotides, with 63 G+C %mol. Comparison with the only other representative of genus *Bifilivirus*, *Propionibacterium* virus B5 (AF428260), revealed that the genome of Philemon is 92.8% identical to the genome of the *Propionibacterium* virus B5, thus fulfilling the criteria for the creation of a separate species. The similarity of morphogenesis protein and CoaB confirms that Philemon belongs to the genus *Bifilivirus*. We propose the name of the species – *Bifilivirus philemonii*.

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

The viruses classified in this proposal do not have a current taxonomic assignment.

**Proposed taxonomic change(s)**

To create a new genus, *Rivavirus*, with three species.

To create a new genus, *Splendidredvirus*, with two species.

To create a new subfamily, *Polsinellivirinae*, with these two genera (*Rivavirus* and *Splendidredvirus*).

To create a new single-species genus, *Prospektnaukivirus*.

To create a new family, *Trautnerviridae*, for these taxa.

**Justification**

Bacillus phage SPP1 was isolated in 1966; sequenced in 1997 (corrected in 2018); and has been the subject of numerous morphological and physiological studies; yet has remained unclassified. In this proposal, it has been assigned to a new genus, *Rivavirus*, together with Bacillus phage vB_BspS_SplendidRed (assigned to the new genus *Splendidredvirus*), to form a new subfamily, *Polsinellivirinae*. The members of this taxon are siphoviruses which have genomes of 42.8–46.3 kb (43.7–44.6 mol% G+C) and encode 74–77 proteins and no tRNAs. As a result of detailed genomic, proteomic and phylogenetic analyses using VIRIDIC, ViPTree and VirClust, we further propose to create a new family for these genera named *Trautnerviridae* named in honour of Thomas A. Trautner.

**Authors:** Shymialevich D, Wójcicki M (michal.wojcicki@hirszfeld.pl), Sokołowska B

### Summary

**Taxonomic rank(s) affected**

Proposal to create a new family, *Mazoviaviridae*, and a new genus, *Dabrowskivirus*, with a single species (class *Caudoviricetes*).

**Description of current taxonomy**

In 2022, significant changes to the taxonomy of bacterial viruses were introduced: the paraphyletic morphological families *Podoviridae*, *Siphoviridae* and *Myoviridae* as well as the order *Caudovirales* were abolished, which is replaced by the class *Caudoviricetes* to group all tailed bacterial and archaeal viruses with icosahedral capsids and a double-stranded DNA genome. Moreover, a binomial system of nomenclature for species was established. Based on the morphology and the comparative analysis of its predicted proteins, *Alicyclobacillus myophage vB_Aac_IAFB_3916* was assigned to viruses with complex structures (class *Caudoviricetes*).

**Proposed taxonomic change(s)**

Analyses of the phylogenetic relationship of *Alicyclobacillus myophage vB_Aac_IAFB_3916* were unable to provide an unambiguous assignment to a specific family and genus. The weak similarity with other phage genomes deposited in the databases suggests that the isolated bacteriophage may be a representative of a new genus and new family of tailed bacteriophages.

**Justification**

The genome of newly isolated *Alicyclobacillus myophage vB_Aac_IAFB_3916* possesses no DNA homologues. At the protein level, this virus is unique. Therefore, we propose the creation of a new species (*Dabrowskivirus KKP3916*), genus (*Dabrowskivirus*) and family (*Mazoviaviridae*) for viruses of this type.

**Authors:** Kurtböke I, Moraru C, Tolstoy I, Kropinski AM (Phage.Canada@gmail.com)

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

At present, the following taxa exist as floating genera in the class *Caudoviricetes*; *Wizardvirus*, *Clownvirus*, *Vividuovirus*, *Dexdertvirus*, *Zitchvirus*, *Kroosvirus* and *Leonardvirus*.

**Proposed taxonomic change(s)**

To create one new species in the genus *Wizardvirus*.

To create a new subfamily, *Frickvirinae* with two genera (*Clownvirus* and *Wizardvirus*).

To add one new species to the genus *Vividuovirus*.

To add one new species to the genus *Dexdertvirus*.

To add four new species to the genus *Zitchvirus*.

To add one new species to the genus *Leonardvirus*.

To create a new subfamily, *Schenleyvirinae*, for the above four genera and *Kroosvirus*.

To create a new family, *Stackebrandtviridae*, for the above-mentioned taxa.

### Justification

Members of the Actinobacteriophage Database Cluster DC (https://phagesdb.org/clusters/DC/) are temperate *Gordonia* phages for which we have created two genera. The related lytic viruses of Cluster DE (https://phagesdb.org/clusters/DE/) have previously been placed in five genera.

## 2024.036B.Caudoviricetes_Faserviricetes_Name_Corrections

**Title:** Corrections to species names in the classes *Caudoviricetes* and *Faserviricetes*

**Authors:** Turner D (dann2.turner@uwe.ac.uk)

### Summary

**Taxonomic rank(s) affected**

Genera and species in realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

All of these species are currently classified within the latest release of the ICTV taxonomy.

**Proposed taxonomic change(s)**

Rename species to conform to the binomial species epithet.

Correct spelling errors.

Create genus to contain a floating species in the subfamily *Tevenvirinae*.

Change to genus name and constituent species in the genus *Roskildevirus* as ‘Roskilde virus’ refers to Norovirus in Danish.

Correction of misspelt genus names in binomial species epithets.

Move two species that were incorrectly classified within the genus *Tequatrovirus*.

Abolish species *Campylobacter* virus IBB35.

**Justification**

To ensure that the naming of viruses is consistent with the guidelines for binomial species names, to remove any names that could cause confusion in native languages and to remove any genome records that do not represent coding complete sequences.

**Title:** Create a new family, *Vandenendeviridae*, for a group of lytic *Pseudomonas* phages (class: *Caudoviricetes*)

**Authors:** Moraru C, Tolstoy I, Kropinski AM (Phage.Canada@gmail.com)

### Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

Five genera are currently classified; *Baldwinvirus*, *Nankokuvirus*, *Otagovirus*, *Flaumdravirus* and *Pakpunavirus*.

**Proposed taxonomic change(s)**

To create seven new single-species genera: *Weillhallvirus*, *Omahavirus*, *Torinovirus*, *Yunamivirus*, *Ventosusvirus*, *Uavernvirus* and *Chemalvirus*.

To create a new genus, *Tartuvirus*, with four species.

To create two new species in the genus *Kremarvirus*.

To create a new family, *Vandenendeviridae*, for these genera and *Baldwinvirus*, *Kremarvirus*, *Nankokuvirus*, *Otagovirus*, *Flaumdravirus*, *Pakpunavirus* and *Shenlongvirus*.

**Justification**

Using VIRIDIC, ViPTree, VIRCLUST and vConTACT v.3.0, we have established that this is a cohesive group of lytic *Pseudomonas* myoviruses which share ≥12.2% DNA sequence similarity and 15 core proteins. The new family is named in honour of Marius van de Ende of South Africa.

## 2024.038B.Vinavirales_3nf_1mf_7ng_5ns_3ms

**Title:** Create three new families *Mestraviridae*, *Asemoviridae* and *Parnassusviridae*, and move the family *Autolykiviridae* into the order *Vinavirales* (*Tectiliviricetes*, *Preplasmiviricota*, *Bamfordvirae*, *Varidnaviria*)

**Authors:** Bardy P, Fogg PCM, Kalatzis PG, Middelboe M, Oksanen HM (hanna.oksanen@helsinki.fi)

### Summary

**Taxonomic rank(s) affected**

The taxonomic ranks affected are the genus *Corticovirus* in the family *Corticoviridae*, the order *Vinavirales* and the family *Autolykiviridae*. In addition, some species are affected.

**Description of current taxonomy**

Currently, the order *Vinavirales* includes one family *Corticoviridae* with one genus *Corticovirus* (two species). The family *Autolykiviridae* belongs to the class *Tectiliviricetes* but is not assigned to any order. The family *Autolykiviridae* includes two genera *Livvievirus* (two species) and *Paulavirus* (three species). The realm *Varidnaviria* to which these taxa are classified has been reorganized in proposal 2024.010D.

**Proposed taxonomic change(s)**

The genus *Corticovirus* (family *Corticoviridae*) is renamed as the genus *Merivirus* and its two species are renamed accordingly. The *Vinavirales* order is rearranged so that the family *Autolykiviridae* is placed in the order along with the family *Corticoviridae*. Two new genera, *Oliviavirus* and *Ameliavirus*, are created in the family *Autolykiviridae*, each with a single species, *Oliviavirus viph1020o* and *Ameliavirus viph1008o*, respectively. The genus of the virus species *Paulavirus viph1044o* is moved from *Livvievirus* to *Paulavirus* (family *Autolykiviridae*). In addition, three new families *Mestraviridae*, *Asemoviridae* and *Parnassusviridae* are created in the order *Vinavirales*. Two new genera, *Anticleavirus* and *Polymedevirus*, are created in the family *Mestraviridae*. One new species is created in each of two genera: *Anticleavirus jorvik* and *Polymedevirus YY*. Two new genera, *Elsinorevirus* and *Rumoivirus*, are created in the family *Asemoviridae*. One new species is created in each of two genera: *Elsinorevirus NO16* and *Rumoivirus VruC*. One new species *Corycianvirus MfV* is created in a new genus *Corycianvirus* in the family *Parnassusviridae*.

**Justification**

The inclusion/creation of four families in the order *Vinavirales*, together with the family *Corticoviridae*, is based on the nine signature genes shared by their members, which corresponds to approximately 50% of their genome. This demonstrates their common evolutionary origin. Classification of *Paulavirus viph1044o* into the genus *Livvievirus* instead of *Paulavirus* was a mistake. To make the names of the family *Corticoviridae* and the genus *Corticovirus* based on a different word stem, the genus *Corticovirus* is renamed *Merivirus*.

### Summary

#### Taxonomic rank(s) affected

*Riboviria, Orthornavirae.*

#### Description of current taxonomy

Realm *Riboviria* includes two kingdoms, *Orthornavirae* and *Pararnavirae*, which include highly diverse viruses that encode RNA-directed RNA polymerases (RdRP) and reverse transcriptases (RT), respectively. Kingdom *Orthornavirae* includes six

<footnote>*Source/full text: https://ictv.global/ictv/proposals/2024.038B.Vinavirales_3nf_1mf_7ng_5ns_3ms.zip.</footnote>
phyla which were established based on phylogenetic analysis of the RdRP and comparative analysis of the viral genomes and proteins.

**Proposed taxonomic change(s)**

We propose to create a new phylum in the kingdom *Orthornavirae* for classification of a group of RNA viruses discovered in hot springs that are characterized by unusual RdRPs.

**Justification**

The RdRPs of hot spring RNA virus 1 and its relatives seem to deviate from the RdRP consensus farther than any of the other recently discovered putative phyla, with none of which they appear to be affiliated, and possess unusual structural features that appear to link them to viral RTs.

## Summary

**Taxonomic rank(s) affected**

**Description of current taxonomy**

The genus *Camvirus* is classified within the subfamily *Arquatrovirinae*, class *Caudoviricetes*.

**Proposed taxonomic change(s)**

Create two new species in the genus *Camvirus*.

**Justification**

We have defined two new species, *Camvirus vanseggelen* and *Camvirus verabelle*, based upon phages isolated for host *Streptomyces coelicolor* from soil samples in the Netherlands at longitude N52°23'31" and latitude E4°34'49". *Camvirus vanseggelen* contains a linear dsDNA genome of 50 426 bp (65.5% G+C) encoding 73 proteins. *Camvirus verabelle* contains a linear dsDNA genome of 49 832 bp (65.0% G+C) encoding 73 proteins. These new species can be included in the genus *Camvirus* together with Streptomyces phage Alsaber, Streptomyces phage Amela, Streptomyces phage phiCAM, Streptomyces phage Endor1, Streptomyces phage Endor2, Streptomyces phage Joe, Streptomyces phage Saftant and Streptomyces phage Sitrop.

**Title:** Create one new genus, *Lacfervirus*, in the class *Caudoviricetes*

## Summary

**Taxonomic rank(s) affected**

Realm *Duplodnaviria*, kingdom *Heunggongvirae*, phylum *Uroviricota*, class *Caudoviricetes*.

**Description of current taxonomy**

The virus classified in this proposal does not have a current taxonomic assignment.

**Proposed taxonomic change(s)**

We propose a new genus, *Lacfervirus*, including a single species for the virus Lactobacillus phage LFP01 in the class *Caudoviricetes*.

**Justification**

The genome of Lactobacillus phage LFP01 has very low homology to all other bacteriophage sequences in the GenBank database. A complete genome sequence comparison using the BLASTn method revealed that the genome of Lactobacillus phage LFP01 had a maximum nucleotide identity of 92.83 and 55% coverage with Lactobacillus phage LF1. The low homology indicated that the newly sequenced bacteriophage likely represents a new genus with a single species.

**Title:** Rename and split an existing genus of the family *Cystoviridae* (*Vidaverviricetes: Mindivirales*), rename seven virus species, create two new species and genera

**Authors:** Poranen MM (minna.poranen@helsinki.fi), Mäntynen S

**Summary**

**Taxonomic rank(s) affected**

The proposal affects species and genus ranks under the family *Cystoviridae*.

**Description of current taxonomy**

The family *Cystoviridae* currently includes one genus *Cystovirus* and seven species, *Cystovirus phi6*, *Cystovirus phi8*, *Cystovirus phi12*, *Cystovirus phi13*, *Cystovirus phi2954*, *Cystovirus phiNN* and *Cystovirus phiYY*. *Cystoviridae* is the only family of the order *Mindivirales* and the class *Vidaverviricetes* that belongs to the phylum *Duplornaviricota* (*Orthornavirae*, *Riboviria*). The other classes in this phylum are *Resentoviricetes* and *Chrymotiviricetes*.

**Proposed taxonomic change(s)**

We propose a new name for the genus *Cystovirus* and its splitting into five genera. Due to the introduction of the new genera, we propose the renaming of all the current species. In addition, we propose to create two new species and two additional new genera in the family *Cystoviridae*.

**Justification**

Seven new dsRNA bacteriophage isolates have been identified and are now proposed to be taxonomically classified to create two new species. Sequence comparisons of these viruses and previously classified dsRNA bacteriophages of the genus *Cystovirus* justify the splitting of the genus *Cystovirus* and the creation of seven genera in the family *Cystoviridae*. The genus *Cystovirus* is renamed to distinguish the name stems of genus and family rank.

**Authors:** Nobrega F.L. (f.nobrega@soton.ac.uk), Rothschild-Rodriguez, D., Lambon, K.

### Summary

**Taxonomic rank(s) affected**

*Duplodnaviria; Heunggongvirae; Uroviricota; Caudoviricetes.*

**Description of current taxonomy**

Unclassified *Caudoviricetes*.

**Proposed taxonomic change(s)**

We propose a new family, *Felixviridae*, which includes the new subfamily, *Maevirinae*, and three genera: *Nakavirus* (new), *Chronisvirus* (new) and *Certevirus* (already existent). The *Nakavirus* and *Chronisvirus* genera include at least one newly proposed species each, *Nakavirus sapi* (for Klebsiella phage Roth C and Klebsiella phage Roth D), and *Chronisvirus chronis* (for Klebsiella phage vB_Kpn_Chronis), respectively.

**Justification**

Phages assigned to this new family have not been taxonomically characterised, with only one previously cultured *Klebsiella* phage relative, vB_Kpn_Chronis, and a Protoea phage, PdC23. We isolated 53 phages as part of the Klebsiella Phage Collection, two of which, RothC and RothD, could not be assigned to any existing viral families, leading us to propose a new family, *Felixviridae*. Additionally, we found representatives of this family to be present in metagenomes originating from human stool samples, a proxy for the human gut microbiota, and in metagenomic sequences within the Gut Phage Database. Genomic analyses suggest that the family *Felixviridae* includes at least one subfamily, *Maevirinae*, and three genera, *Certevirus* and two new genera *Nakavirus* and *Chronisvirus*. The *Nakavirus* genus includes species for Klebsiella phage Roth C and Klebsiella phage Roth D. High similarity between these viruses places them both in the proposed species *Nakavirus sapi*. The *Chronisvirus* genus includes the species *Chronisvirus chronis* for phage vB_Kpn_Chronis.

## 2024.045B.Autographivirales

**Title:** Promoting the family *Autographiviridae* to create one new order, *Autographivirales*, with four new families, four new subfamilies, 93 new genera and 607 new species (*Duplodnaviria*, *Caudoviricetes*).

**Authors:** Turner D (dann2.Turner@uwe.ac.uk), Carrillo D, Lood C, Ely B, Lehman SM, Dutilh B, Kropinski AM, Lavigne R, Adriaenssens EM, Millard AD

### Summary

**Taxonomic rank(s) affected**

Realm: *Duplodnaviria*; kingdom: *Heunggongvirae*; phylum: *Uroviricota*; class: *Caudoviricetes*.

**Description of current taxonomy**

The family *Autographiviridae* was established under taxonomic proposal 2019.103B.

**Proposed taxonomic change(s)**

We propose

The establishment of a new order, *Autographivirales*, containing four new families.

The creation of four new subfamilies.

The creation of 93 new genera.

The creation of 610 new species.

Abolition of 21 species.

**Justification**

The proposed order forms a single deep-branching clade in tBLASTx distance analysis, reflected in core gene maximum- likelihood phylogeny. The proposed families form monophyletic clusters in proteome-based analyses and each share a number of core orthologous genes.
