Aspiviridae, formerly Ophioviridae, is a family of segmented negative-strand RNA viruses which infect plants. Member viruses are characterized by an elongated and highly filamentous and flexible nucleocapsid with helicalsymmetry.[1] It is a monotypic taxon containing only one genus, Ophiovirus.[2]Aspiviridae is also the only family in the order Serpentovirales, which in turn is the only order in the class Milneviricetes.[3]
The name Aspiviridae derives from the Latinaspis (snake or viper), referring to the shape, along with the suffix for a virus family -viridae.[4]Ophiovirus derives from the Ancient Greekophis, "snake", with –virus the suffix for a virus genus.[5] Likewise, Serpentovirales is from "serpent" with -virales the suffix for a virus order.[4]Milneviricetes is in honor of Robert G. Milne, the last author on the first paper describing ophioviruses.[4][6]

The protein capsid is non-enveloped and has a constant diameter of 1500–2500 nm and a width of 3 nm, or 9 nm. The capsids form kinked circles, which can collapse to form linear duplex structures, much like a spring.[3]
