A novel iflavirus, tentatively named "Sogatella furcifera honeydew virus 1" (SFHV1), discovered through transcriptome sequencing analysis of white-backed planthoppers (Sogatella furcifera) collected in southern China, is described here. The full genome of SFHV1 is 10,837 nucleotides (nt) long, including the polyA tail, and shares 65.5% and 64.5% genomic identity with Laodelphax striatellus picorna-like virus 2 and Laodelphax striatella honeydew virus 1, respectively. On the basis of the phylogenetic analysis of the complete genomic sequence and the deduced RdRp amino acid sequence of SFHV1 with other iflaviruses, we suggest that it is a member of a new species in the genus Iflavirus, family Iflaviridae.
