'Athyris' originates from New Latin as a scientific genus name, likely formed from Greek elements such as the prefix 'a-' (meaning 'not' or 'without') combined with a root related to 'thyr-'/'thyra' (from Greek θυρά, 'door' or 'opening'), though the exact formation is taxonomic/coined usage.

'Athyris' was coined as a genus name in 19th-century paleontological taxonomy (New Latin) and has been used in scientific literature since its establishment to designate this group of brachiopods.

Originally introduced as a taxonomic label for this group of brachiopods; its sense has remained specialized as the formal genus name in paleontology.
