Bettongs, species of the genus Bettongia, are potoroine marsupials once common in Australia. They are important ecological engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat.
All species of the genus have been severely affected by ecological changes since the European settlement of Australia. Those that have not become extinct became largely confined to islands and protected reserves and are dependent on re-population programs. The diversity of the genus was poorly understood before their extirpation from the mainland, and new taxa have been identified in specimens newly discovered and already held in museum collections.
- Bettongia gaimardi, Eastern bettong, also known as the Tasmanian bettong
- Bettongia lesueur Boodie
- Bettongia penicillata Woylie
- Bettongia tropica Wakefield, 1967. Northern bettong
In addition, at least three extinct species are known:
- Bettongia moyesi, Middle Miocene bettong from Riversleigh
- Bettongia pusilla, Nullarbor dwarf bettong, known only from subfossil remains, probably became extinct after colonisation
- Bettongia anhydra, described in 2015 from a specimen collected in 1933 near Lake Mackay, Northern Territory.
A conservative arrangement of modern and fossil taxa of Bettongia may be summarised as
- family Potoroidae:
- genus Aepyprymnus
- genus Bettongia
