Sciurinae is a subfamily of squirrels in the (family Sciuridae), uniting the flying squirrels with certain related tree squirrels. Older sources[citation needed] place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.[1]
