Two bunyaviruses, Bhanja (BHAV, LEIV-Az1818) isolated from the Ixodes ticks Rhipecephalus bursa (Canestrini and Fanzago, 1878) in Azerbaijan (1973) and Razdan (RAZV; strain LEIV-Arm2741) isolated from the Dermacentor marginatus (Sulzer, 1776) ticks in Armenia (1972), were de novo sequenced (on the Illumina platform). The amino acid identity between these viruses proteins were 95.8% (RdRp, L-segment), 90.3% (GnGc, M-segment), and 92.5% (N, S-segment). Thus, RAZV was classified to BHAV group. GnGc protein identity of RAZV withEuropean BHAV strains is more than 90%. With the African Forécariah virus (FORV) RAZV has 85% identity. BHAV LEIV-Az1818 is most closely related to the Indian strain BHAV IG690 (99%), while showing 90% identity with the European BHAV isolates. The genome structure of BHAV and RAZV is typical of the tick-transmitted phleboviruses. Based onthe result of the molecular-genetic and phylogenetic analysis RAZV has been classified as belonging to BHAVgroup in the genus Phlebovirus (Bunyaviridae).
