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
