Namdapha Flying Squirell
scientific name: Biswamoyopterus biswasi
Last seen: 1981 in India
Years lost: 37
The Namdapha Flying Squirrel is only known with certainty from a single specimen collected in Namdapha National Park, the largest protected area in the Eastern Himalaya biodiversity hotspot, at altitudes of between 100 and 350 meters above sea level. Although researchers have surveyed the surrounding area for the flying squirrel, there have not been any verified sightings of the species. Scientists believe the Namdapha Flying Squirrel occurs in dry deciduous montane forests along streams, and may be restricted to the area of a single valley within the Namdapha National Park. This is an arboreal species that is likely most active at dusk.
