is a family of retrotransposons and reverse-transcribing viruses with long terminal repeats belonging to the order . Members of the genera and include, respectively, Saccharomyces cerevisiae Ty3 virus and its Gypsy-like relatives in drosophilids. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family which is available at ictv.global/report/metaviridae.
