Cercartetus lepidus (Thomas, 1888) is a burramyid commonly called the little pygmy-possum. It is 1 of 4 species in the genus Cercartetus, which together with Burramys parvus form the marsupial family Burramyidae. This Lilliputian possum has a disjunct distribution, occurring on mainland Australia, Kangaroo Island, and in Tasmania. Mallee and heath communities are occupied in Victoria and South Australia, but in Tasmania it is found mainly in dry and wet sclerophyll forests. It is known from at least 18 fossil sites and the distribution of these reveal a significant contraction in geographic range since the late Pleistocene. Currently, this species is not listed as threatened in any state jurisdictions in Australia, but monitoring is required in order to more accurately define its conservation status.
