Phylogeny of the genus Hepatovirus (representative viruses only) based on the RNA-dependent RNA polymerase gene (alignment length of 2201 amino acids post trimming). The virus from this study (toutouwai hepatovirus) is shown in red and has a ‘+’ after the name. The avian clade is shown by the blue tips and labels. Viruses found in birds are marked with a bird silhouette. Related viruses are shown in black. Black circles on nodes show bootstrap support values of more than 90%. Branches are scaled according to the number of amino acid substitutions per site, shown in the scale bar. The tree is midpoint rooted for purposes of clarity only
