Viruses in the family Rhabdoviridae are ecologically very diverse, infecting mammals, birds, reptiles, fish, plants and a wide range of other terrestrial and aquatic invertebrates. The genus Sripuvirus currently comprises five viruses that appear to circulate in transmission cycles involving reptiles and sandflies. Here, we report an analysis of the complete coding sequences of Cuiaba virus (CUIV), isolated from an amphibian (Bufo marinus) collected in Brazil, and Charleville virus (CHVV), isolated from sandflies (Phlebotomus sp.) and lizards (Gehyra australis), collected in Australia. CUIV and CHVV cluster phylogenetically with the sripuviruses in maximum likelihood trees generated from complete L protein (RdRp) sequences. They also share with sripuviruses unique features in genome organisation, including an additional gene (U1) between the matrix protein (M) gene and glycoprotein (G) gene, and an alternative long open reading frame near the start of the G ORF that encodes a predicted transmembrane protein. In view of their phylogenetic relationships, similar genome organisations and similar ecological characteristics, we propose the assignment of CUIV and CHVV as novel members of the genus Sripuvirus.
