MDD taxon ID1001659
Current MDD recognizes this as a living species in tribe Pteromyini.
02 · HABITAT
Where it lives
Current MDD country distribution: Brunei · Indonesia · Malaysia. Species-specific forest type, elevation limits and microhabitat use are not fully summarized here. Genus context: Southeast Asian tropical and island forest.
03
Shelter, Nest & Resting Sites
Species-specific den and nest data: Unknown. Genus context: tree cavities and protected arboreal sites are typical context; exact species details often unknown. This is context, not a substitute for direct observations of Whiskered Flying Squirrel.

AppearanceSpecies-specific adult measurements and diagnostic pelage details are not yet sufficiently standardized in available species-specific references. Genus context: Petinomys is a small-to-medium flying-squirrel lineage; exact field identification should use locality, measurements and current taxonomic references together.

05
Gliding Anatomy & Locomotion
As a member of Pteromyini, this species uses a furred patagium between the fore- and hind limbs for controlled gliding. Wrist-supported membrane anatomy and the tail contribute to lift, steering, braking and landing. Species-specific maximum glide distance: Unknown.
Pteromyini context: Flying squirrels glide rather than perform powered flight. The patagium creates an aerodynamic surface, specialized wrist structures help support that surface, and the flattened or bushy tail contributes to stability and control.
06
Behavior, Activity & Communication
Activity: nocturnal arboreal glider; many species remain poorly studied
Social system: Unknown at species-specific detail.
Communication: Unknown at species-specific detail. Flying squirrels also use scent, posture and acoustic signals, but a species-specific repertoire is not assigned without direct evidence.
BEHAVIOR & FORAGING CONTEXT

These are related flying squirrels, not photographs of Whiskered Flying Squirrel. Use them as visual context for locomotion, posture, feeding and environmental use.
07
Diet & Foraging
Species-specific diet: Unknown or incompletely documented in available references. Genus context: fruits, seeds and other plant foods with possible invertebrate use; exact species data vary.

Predation & Risk
Species-specific predator list: Unknown. Flying squirrels are broadly preyed on by nocturnal raptors, snakes and mammalian carnivores, with the exact predator community depending on region.

Ecology & Ecosystem Role
Species-specific ecological role is incompletely documented. Genus context: forest consumer and prey; island endemics can be especially sensitive to habitat loss.

Conservation
CURRENT MDD / IUCN STATUSVulnerable
Current MDD status shown above. Species with narrow island or montane distributions can face serious local habitat pressure even when a global assessment is not available.
12
Research Coverage & Unknowns
Natural-history coverage is incomplete. Taxonomy, current country distribution and conservation category are anchored to MDD; unsupported measurements, reproduction and lifespan remain Unknown rather than inferred from relatives.
Genus context: Petinomys is a small-to-medium flying-squirrel lineage associated broadly with Southeast Asian tropical and island forest. This is genus-level context where direct species-specific data are missing.
