The Northern is distributed from Townsville north to Cape York. Anything below that is Southern.I'd really like to know the exact distribution of the two LnB species. Do you know if there's any info out there?
In the paper describing pallescens as a full species they also suggested that the animals from the middle part of eastern Queensland (e.g. around the Mackay area) may be a separate subspecies of Southern but didn't go further because it would need more study.
The link below should work for a pdf of the paper (which has maps etc as well as all the technical stuff), but if not you can find it on Google Scholar with the title "Investigating dental variation in Perameles nasuta Geoffroy, 1804, with morphological evidence to raise P. nasuta pallescens Thomas, 1923 to species rank"
