MDD notes that the small number of Biswamoyopterus specimens leaves species limits in this genus open to further study.

02 · DISTRIBUTION

Where it occurs

Current MDD country distribution: India · Myanmar.

Country-level distribution is a broad map, not a claim that the species occurs throughout every listed country.

02 · HABITAT

Where it lives

Current MDD country distribution: India · Myanmar. Species-specific forest type, elevation limits and microhabitat use are not fully summarized here. Genus context: montane/subtropical forest in South and Southeast Asia.

03

Shelter, Nest & Resting Sites

Species-specific den and nest data: Unknown. Genus context: Unknown; the genus is known from very few records. This is context, not a substitute for direct observations of Namdapha Flying Squirrel.

AppearanceSpecies-specific adult measurements and diagnostic pelage details are not yet sufficiently standardized in available species-specific references. Genus context: Biswamoyopterus is a large 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: rare nocturnal glider; natural history remains one of the largest data gaps in Pteromyini

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

Conservation

CURRENT MDD / IUCN STATUSCritically Endangered

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: Biswamoyopterus is a large flying-squirrel lineage associated broadly with montane/subtropical forest in South and Southeast Asia. This is genus-level context where direct species-specific data are missing.
