Derivation of names
Atripovirus: from Atropos - one of the three Fates
Gandrviridae: from Jörmun gandr, a serpent in Norse mythology equivalent of ouroboros. The prefix "Jörmun-" denotes something huge, the word "gandr" refers to elongated entities, including snakes, referring to the genome circularity of members of the family; the suffix viridae for family taxa
Meliavirus: from Meliae - nymphs of the ash-tree
Oreadivirus: from Oreads - the nymphs of trees, groves, woodlands and mountain forests
Oreiadivirus: from Oreiades - nymphs of the mountains
Satyrivirus: from Satyrs - rustic fertility spirits of the countryside and wild
Sthenivirus: from Stheno - one of the two immortal Gorgons
Thisbivirus: from Thisbe - the eponymous nymph of the Boeotian town of Thebes
Thyiavirus: from Thyia - the Naiad-nymph of Mount Parnassus loved by the god Apollo
