Petauridae is a family of possums containing 14 species: four species of trioks and striped possum (genus Dactylopsila), eight species of wrist-winged glider (genus Petaurus), and Leadbeater's possum (Gymnobelideus leadbeateri), which has only vestigial gliding membranes. Most of the wrist-winged gliders are native to Australia, whereas most of the striped possums to New Guinea, but some members of each group are found on both sides of the Torres Strait. Leadbeater's possum is endemic to Victoria, Australia.

== Evolution == All petaurids have obvious facial markings, a well-defined dorsal stripe, very large lower front incisors, and four-cusped molars. Despite their distinctive appearance, petaurids are closely related to the ringtail possums (family Pseudocheiridae) and are grouped together with them to form the superfamily Petauroidea.
