Range Description

This species is known only from Mount Somoro, and adjacent areas, in the Torricelli Mountains of north-western Papua New Guinea. Fossil records indicate that the species never occurred in the Bewani range, so appears to be confined to the Torricelli range. It has been recorded at 1,000 and 1,220 m asl. It may range as low as 300 m asl, although this requires confirmation.
