artoviridae artoviridae artoviridae is a family of negative-strand rna viruses in the order mononegavirales. barnacles, copepods, odonates, parasitoid wasps, pile worms, and woodlice serve as natural hosts. the group name derives from arthropod the phylum of its hosts. members of the family were initially discovered by high throughput sequencing. artoviridae electron micrographs of ppnsrv-1 purified particles virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: negarnaviricota class: monjiviricetes order: mononegavirales family: artoviridae structure artovirus genome organization virions are enveloped, spherical particles, 100 to 130 nm in diameter, and the virus genome comprises about 12 kb of negative-sense, unsegmented rna. taxonomy the following genera and species are recognized: genus: hexartovirus barnacle hexartovirus caligid hexartovirus genus: peropuvirus beihai peropuvirus hubei peropuvirus odonate peropuvirus pillworm peropuvirus pteromalus puparum peropuvirus woodlouse peropuvirus
