Unidentified Khurdun virus (KHURV) was isolated in 2001 from coot (Fulica atra, Linnaeus, 1758) in the Volga River delta (Astrakhan Region, Russian Federation). Here we report that the KHUV genome was de novo sequenced (on Illumina platform) and the KHURV was classified as a novel prototypic bunyavirus. The KHURV genome comprises three negative-sense RNA segments (L, M, and S); its terminal nucleotide sequences are canonical for the Orthobunyavirus genus. Based on the results of the molecular-genetic and phylogenetic analysis we suggest that the KHURV belongs to the genus Orthobunyavirus (Bunyaviridae).
