Two ‘Extinct’ Marsupials Confirmed Alive in New Guinea, One Placed in New Genus

Researchers are beginning targeted surveys with Indigenous partners to secure habitats threatened by logging, with locations withheld to deter wildlife trade.

Overview

  • Peer‑reviewed studies and museum statements confirm live populations of the pygmy long-fingered possum (Dactylonax kambuayai) and the ring-tailed glider (Tous ayamaruensis) in West Papua’s Vogelkop Peninsula.
  • The glider is assigned to a newly created genus, Tous, based on distinct traits such as a prehensile tail and unfurred ears, while the possum is marked by a greatly elongated fourth digit for extracting insect larvae.
  • The identifications synthesize Holocene fossil evidence, reexamined museum specimens—including misidentified jarred samples—and modern photographs contributed by citizen scientists on platforms like iNaturalist.
  • Local knowledge from Tambrauw and Maybrat communities proved pivotal, with some groups culturally protecting the glider, which nests in hollows of tall rainforest trees.
  • Scientists warn of logging and potential wildlife trade risks, note the species’ specialized needs that make captivity unviable, and prioritize mapping ranges and assessing protection within national parks.
