Alvernaviridae is a family of non-enveloped positive-strand RNA viruses.

There is one genus in this family, Dinornavirus, which contains one species: Heterocapsa circularisquama RNA virus 01.

Diseases associated with this family include host population control, possibly through lysis of the host cell.

[1][2] Viruses in Alvernaviridae are non-enveloped, with icosahedral and spherical geometries, and T=3 symmetry.

[1] Genomes are linear and non-segmented, around 4.4kb in length.
