The Nullarbor Dwarf Bettong was described very recently (McNamara 1997). It is known only from subfossil material, but is considered to have been extant at European settlement, e.g. Baynes (1987 as ‘unnamed potoroid’) placed it in the modern mammal fauna of the Nullarbor Plain. It has never been reported alive (Boscacci et al. 1987).
