Yuyuevirus is a genus of negative-strand RNA viruses which infect invertebrates.[1] Member viruses have bisegmented genomes.[2] [3] 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.
The name Yuyuevirus is from Chinese: 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 Chinese: 越, also referring to Yuè state, with the suffix for virus family -viridae. Goujianvirales is named in honor of Goujian (Chinese: 勾踐) the king of Yuè State. Yunchangviricetes is named in honor of Yǔncháng (Chinese: 允常), the father of Gōujiàn.
Yuyueviruses have negative-sense, single-stranded RNA genomes that are bisegemented. The total genome length is 7.8–8.2 kbp.
The genus contains two species:
