mivirus mivirus mivirus is a genus of negative-strand rna viruses which infect arthropods. member viruses have nonsegmented and bisegmented genomes. there are nine species in the genus. mivirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: negarnaviricota class: monjiviricetes order: jingchuvirales family: chuviridae genus: mivirus etymology the name mivirus derives from 芈 (mǐ), the ancestral name of king zhuang of chu during the spring and autumn period, along with -virus, the suffix for a virus genus. genome the differing genome organizations in the family chuviridae miviruses have nonsegmented and bisegmented genomes which are linear. some member viruses may have circular genomes. taxonomy phylogentic tree of negarnaviricota with family chuviridae in blue the following species are recognized: mivirus amblyommae mivirus boleense mivirus changpingense mivirus dermacentoris mivirus genovaense mivirus karukeraense mivirus rhipicephali mivirus suffolkense mivirus wuhanense
