Subfamily of prosimians belonging to the adapoid family Adapidae. Adjective: adapine. Known from the late Eocene to early Oligocene; five genera and twelve species. Recent revision of the adapoids has resulted in this subfamily being reduced in size as well as becoming the only subfamily of the adapids. All members are characterized by a molarized fourth premolar that is equipped with shearing crests. Dental formula variable over time. Unlike modern prosimians, the mandible is fused. Body mass estimated to range between 600 g and 4 kg for the included genera. Analysis of the limb bones led some workers to suggest that the adapids employed a slow methodical climbing locomotion similar to extant lorisoids (Lorisoidea), but others think that there was more diversity of locomotor behavior in this group.
