order: Xenadelphovirales (current release)

Etymology: From the Greek xenos, meaning “alien” and the Ancient Greek ἀδελφός (adelphos), meaning "brothers", referring the evolutionary relationship of two families in the order (Polymycoviridae and Hadakaviridae) despite their differences in genome structure and virion formation; the suffix ‑virales for order taxa
