Family: Peribunyaviridae

Genus: Shangavirus


Distinguishing features

Shangavirus RNA has been found in a mixed-insect pool from China containing both chrysopids (green lacewings) and moth flies (Psychoda alternata) (Li et al., 2015). There currently is no cultured shangavirus isolate.



Not described.

Nucleic acid

The shangavirus genome consists of three segments of negative-sense RNA (Li et al., 2015). Analysis of the terminal sequences has yet to be completed.


In silico analysis of shangavirus putative ORF sequences suggests shangaviruses encode a protein with RNA-directed RNA polymerase and endonuclease functions (L), the glycoproteins Gn and Gc, the non-structural protein NSm, and the nucleoprotein N, but not the non-structural protein NSs (Table 2.Peribunyaviridae; Figure 1.Shangavirus) (Li et al., 2015).


Not described.


There are 1 and 9 N-glycosylation sites on Gn and Gc, respectively (Li et al., 2015).

Genome organization and replication

The shangavirus genome is similar to the genomes of other peribunyaviruses. The S, M, and L segments putatively encode N, Gn and Gc, and L proteins, respectively (Li et al., 2015).


Figure 1. ShangavirusShangavirus coding strategy. vcRNAs are depicted in 3'→5' direction and mRNAs are depicted in a 5'→3' direction. The mRNAs depict ORFs that encode the N, nucleocapsid protein; Gn and Gc, external glycoproteins; L, large protein, as well as the non-structural protein NSm. 

The shangavirus mode of replication is unknown.


Unknown, but suggested to be an insect-specific virus.

Species demarcation criteria

Not defined as the genus currently includes only a single species.
