Artoviridae is a family of negative-strand RNA viruses in the order Mononegavirales.

[1][2] Barnacles, copepods, odonates, parasitoid wasps, pile worms, and woodlice serve as natural hosts.

[2] The group name derives from arthropod the phylum of its hosts.

[3] Members of the family were initially discovered by high throughput sequencing.

[4][5] Virions are enveloped, spherical particles, 100 to 130 nm in diameter, and the virus genome comprises about 12 kb of negative-sense, unsegmented RNA.
