This small rodent is recorded in the mountains of southern New Guinea. The confirmed record is from Mount Bosavi; two specimens from Mount Karimui were only tentatively assigned in the original paper.
The Mount Bosavi holotype had pale ears and a pale, more heavily mottled and hairy tail.
The confirmed record is the type locality in montane forest at 2,100 m on the north-northwestern slopes of Mount Bosavi.
