The prefix "prisca" comes from the Latin meaning old, ancient, primeval or primitive.[2] It was used to indicate that this genus is one of the oldest and simplest form of the koala.[2] The species P. lucyturnbullae was named for Lucy Turnbull a businesswoman, wife of former Prime Minister Malcolm Turnbull, and supporter of the research that discovered the genus.[2]
