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.
