We report the first record of the White-bellied flying squirrel Petaurista albiventer (Gray, 1834), within the Katarniaghat Wildlife Sanctuary, which is part of the Terai Arc Landscape in India. This marks a new geographical distribution for P. albiventer within the Indian state of Uttar Pradesh. This study contributes to the understanding of the geographical distribution, habitat ecology and taxonomy of the genus Petaurista (Link, 1795), shedding light on its presence in various ecologically significant regions and emphasizing the importance of preserving its habitat and promoting further research.
