Viruses assigned to the genus Lostrhavirus form a distinct monophyletic group based on well-supported Maximum Likelihood or Maximum Clade Credibility trees inferred from complete L sequences. Lostrhaviruses have been detected in hard ticks (Ixodidae). Lone star tick rhabdovirus (LSTRV; species Lostrhavirus lonestar) was detected in a tick collected from a patient with a rash illness.
Viruses assigned to the genus Caligrhavirus form a distinct monophyletic group based on well-supported Maximum Likelihood or Maximum Clade Credibility trees inferred from complete L sequences. Viruses assigned to the genus have been detected in sea lice (Copepoda: Caligidae).
Viruses assigned to the genus Alphanemrhavirus form a distinct monophyletic group based on well-supported Maximum Likelihood or Maximum Clade Credibility trees inferred from complete L sequences. Viruses assigned to the genus have been detected in parasitic nematodes (roundworms of the phylum Nematoda).
Viruses assigned to the genus Tupavirus form a distinct monophyletic group based on well-supported Maximum Likelihood or Maximum Clade Credibility trees inferred from complete L sequences. Tupaviruses infect mammals and birds. The genome organisation features an alternative long ORF (Px or C) in the P gene and a gene encoding a small hydrophobic protein (U1 or SH) between the M gene and the G gene.
