Four extant species are recognised: •
Eastern bettong (
B. gaimardi) •
Boodie (
B. lesueur) •
Woylie (
B. ogilbyi) •
Northern bettong (
B. tropica) The recently extinct species are: •
Desert bettong (
B. anhydra). Only known from one specimen collected in the Tanami in 1933 and subfossil material from the Nullarbor. The causes of extinction are presumed to be predation by feral cats and foxes, and changes to the fire regime. •
Nullarbor dwarf bettong (
B. pusilla). Known only from subfossil remains but considered to have survived until European settlement. • Brush-tailed bettong (
B. penicillata). Previously a senior synonym of the Woylie (
B. ogilbyi), it was recently split. •
Little bettong (
B. haoucharae). Known from subfossil and mummified remains from the Nullarbor Plain's and Great Victoria Desert. The phylogeny of the genus has seen a grouping of 'brush-tailed' taxa allied within the genus
Bettongia, and this includes the extant species
Bettongia gaimardi,
B. tropica and
B. penicillata. A conservative arrangement of modern and fossil taxa of
Bettongia may be summarised as • family
