The Namdapha flying squirrel is endemic to Arunachal Pradesh in northeast India. It inhabits tall Mesua ferrea jungles, often on hill slopes in the drainage basin area of Dihing River, particularly on the western slope of Patkai range in northeastern India. Field observations suggest that the Namdapha flying squirrel primarily feeds on young leaves and shoots in the upper canopy of subtropical evergreen forests, indicating a folivorous diet closely tied to mature forest habitat.
