# Sciurinae

Sciurinae (/sɪˈjuːrɪneɪ/) is a subfamily of squirrels (in the family Sciuridae), uniting the flying squirrels with certain related tree squirrels. Older sources 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.
