PhylumChordata
ClassMammalia
OrderRodentia
FamilySciuridae

SpeciesPetaurillus emiliae
MDD taxon ID1001635
Current MDD recognizes this as a living species in tribe Pteromyini.
02 · HABITAT
Where it lives
Current MDD country distribution: Indonesia · Malaysia. Species-specific forest type, elevation limits and microhabitat use are not fully summarized here. Genus context: Bornean and Malaysian tropical forest.
03
Shelter, Nest & Resting Sites
Species-specific den and nest data: Unknown. Genus context: small arboreal cavities or protected tree sites are expected, but direct data are sparse. This is context, not a substitute for direct observations of Lesser Pygmy Flying Squirrel.
RANGE & HABITAT CONTEXT

AppearanceSpecies-specific adult measurements and diagnostic pelage details are not yet sufficiently standardized in available species-specific references. Genus context: Petaurillus is a very small / pygmy 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: tiny nocturnal arboreal glider; among the least studied flying squirrels
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.

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: likely small-scale consumer of fruits/seeds/invertebrates; direct studies are limited.

Conservation
CURRENT MDD / IUCN STATUSNot Evaluated
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: Petaurillus is a very small / pygmy flying-squirrel lineage associated broadly with Bornean and Malaysian tropical forest. This is genus-level context where direct species-specific data are missing.
