''Insthoviricetes''. The order contains two families and eight genera.

Etymology

The order name ''Articulavirales'' derives from Latin meaning "segmented" (alluding to the segmented genome of member viruses) added to the suffix for virus orders ''-virales''. The class name ''Insthoviricetes'' is a

Genome

Member viruses have segmented, negative-sense, single-stranded RNA genomes.
