Phylogenetic analyses of OMRV based on complete genomes using Neighbor Joining methods. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches. The tree is unrooted. The evolutionary distances were computed using the Kimura 2-parameter method and are in the units of the number of base substitutions per site. All OMRV strains are grouped into 3 clades. ◆ indicates the sequence of this study. The labels on the upper left indicate hosts of OMRVs. The arrow indicates an outgroup (Drosophila melanogaster totivirus SW-2009a)
