Cruliviridae is a family of negative-sense RNA viruses with genomes of 10.8–11.5 kb that have been found in crustaceans. The crulivirid genome consists of three RNA segments with ORFs that encode a nucleoprotein (NP), a glycoprotein (GP), a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain, and in some family members, a zinc-finger (Z) protein of unknown function. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Cruliviridae, which is available at ictv.global/report/cruliviridae.

“…Current taxonomy: ictv.global/taxonomy. Wupedevirids are most closely related to arenavirids, discovirids, leishbuvirids, mypovirids, nairovirids, and phenuivirids [2–4] (). The family includes the genus Wumivirus for viruses that infect myriapods (millipedes).…”

Wupedeviridae is a family of negative-sense RNA viruses with genomes of about 20.5 kb that have been found in myriapods. The wupedevirid genome consists of three monocistronic RNA segments with open reading frames (ORFs) that encode a nucleoprotein (NP), a glycoprotein (GP), and a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Wupedeviridae, which is available at ictv.global/report/wupedeviridae.

“…The yuevirid genome comprises two segments of linear negative-sense RNA with a total length of 7.8–8.2 kb (large (L) segment, 6.6–6.9 kb; small (S) segment, 1.2–1.3 kb) [1–5] (, ). The L segment ORF ( L ) encodes an RNA-directed RNA polymerase (RdRP) with a GDP : polyribonucleotidyltransferase (PRNTase) domain that is related to that of viruses in the order Mononegavirales , suggesting a similar capping mechanism.…”

“…Unclassified yuevirids have been associated with diverse crustaceans and insects [6], stramenopiles [7][8][9], tracheophytes [3], and unspecified macrophytes [5]. Thus, the diversity of yuevirids is likely vastly underestimated [2,4].…”

Yueviridae is a family of negative-sense RNA viruses with genomes of 7.8–8.2 kb that have been associated with crustaceans, insects, stramenopiles and plants. The yuevirid genome consist of two segments, each with at least one ORF. The large (L) segment ORF encodes a large protein containing an RNA-directed RNA polymerase domain. The small (S) segment ORF encodes a nucleocapsid protein. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Yueviridae, which is available at http://www.ictv.global/report/yueviridae.
