New records of the Southern Flying Squirrel (Glaucomys volans) in Quebec expand its known range in the province 150 km east to the appalachian foothills and farther west than previously assumed. We obtained individuals through live trapping, trapper collaboration, and opportunistic discoveries. Species identification was confirmed with morphological traits and molecular analysis. individuals were smaller in the eastern part of the province in terms of mass, total length, and tail length. Some live captures also seem to corroborate the fact that Southern Flying Squirrels are mainly associated with mature hardwood forests.
De nouvelles mentions du petit polatouche (Glaucomys volans) au Québec permettent d’étendre son aire de répartition connue jusqu’à 150 km à l’est dans les contreforts des appalaches et plus à l’ouest que présumé. Les spécimens ont été obtenus via des captures vivantes, la collaboration des trappeurs et des découvertes opportunistes. L’identification de l’espèce a été confirmée sur des bases morphologiques et moléculaires. Les individus étaient plus petits dans l’est de la province en considérant la masse, la longueur totale et celle de la queue. Les quelques captures d’animaux vivants semblent corroborer que le petit polatouche est davantage associé, au niveau de l’habitat, aux peuplements de feuillus matures.
