This species is widespread throughout the central mountains of New Guinea (Indonesia and Papua New Guinea), the Foja Mountains (Indonesia), and the Huon Peninsula (Papua New Guinea), but it has a very patchy distribution and is probably now extirpated from most of its range (specimens are very common in the fossil record). Historically, it has been recorded from sea level to around 4,150 m asl. It is, however, rarely found at sea level now.
