''Insthoviricetes''. The order contains two families and eight genera. Metatranscriptomics of aquatic animal samples paired with phylogenetics suggests that Articulavirales exhibits complex cross-species virus transmission and virus-host co-divergence over deep evolutionary time scales. Potentially originating in ancient aquatic animals at least 600 Mya.

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

portmanteau In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed by combining the meanings, and parts of the sounds, of two or more words together.

of member viruses "''in''fluenza, i''s''avirus, and ''tho''gotovirus" added to the suffix ''-viricetes'' for virus classes.

Genome

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