Perameles pallescens is a marsupial from the genus long-nosed buccaneers , which occurs in the north-eastern coastal region of Queensland from Townsville in the south to the Cape York Peninsula in the north. The form was described in 1923 by the British zoologist Oldfield Thomas as a subspecies of the great long-nosed bucket ( Perameles nasuta ), but has been considered an independent species since 2016. Comparisons of mitochondrial and nuclear DNA ( nuclear DNA ) showed that the in New South Wales and in eastern Victoria occurring nominate form ( P. nasuta nasuta ) is more closely related to the Tasmanian long-nosed bag ( Perameles gunnii ) than to the northern form that lives in the humid tropics. The comparison of the skull morphology shows a sister group relationship between Perameles pallescens and Perameles nasuta with Perameles gunnii as a sister species of the clade of P. pallescens and P. nasuta .
features
Perameles pallescens has gray-brown fur on the head, back and sides of the body. The peritoneum and the front and rear paws are whitish or cream-colored. The muzzle is long and pointed and the ears are pointed and are usually held upright.
Outwardly , Perameles pallescens does not differ from the large long-nosed pouch ( Perameles nasuta ) . However, the formation of the tooth cusps is different and the males of Perameles pallescens lack the crest or are only very rudimentary. Perameles pallescens can be distinguished from the Tasmanian long-nosed pouch ( Perameles gunnii ) and the striped long-nosed pouch ( Perameles bougainville ) mainly by the almost uniform coloring of the body sides, while the other two species show two to four light, vertical stripes on the back of the body. Further differences concern the tooth morphology and, in the case of the striped long-nosed pouch, the skull morphology. Perameles pallescens is significantly larger than the Tasmanian long-nosed pouch and the striped long-nosed pouch.
habitat
Perameles pallescens occurs in rainforests, moist evergreen deciduous forests, in swamps and on farmland. Compared to the large long-nosed bucket, Perameles pallescens is rare.
