Yuyuevirus

Yuyuevirus is a genus of negative-strand RNA viruses which infect invertebrates. Member viruses have bisegmented genomes. It is the only genus in the family Yueviridae, which in turn is the only family in the order Goujianvirales and class Yunchangviricetes. Two species are recognized: Beihai yuyuevirus and Shahe yuyuevirus.

Etymology
The name Yuyuevirus is from 於越, a synonym for the Spring and Autumn period state of Yuè, along with -virus, the suffix for a virus genus Yueviridae comes from 越 , also referring to Yuè state, with the suffix for virus family -viridae.

Genome
Yuyueviruses have negative-sense, single-stranded RNA genomes that are bisegemented. The total genome length is 7.8–8.2 kbp.

Taxonomy

 * Beihai yuyuevirus
 * Shahe yuyuevirus
