Glaresis is a
genus of
beetles, sometimes called "enigmatic scarab beetles", in its own family, the
Glaresidae. It is closely related to, and was formerly included in, the family
Scarabaeidae. Although its members occur in arid and sandy areas worldwide (except Australia), only the nocturnal adults have ever been collected (typically at lights), and both the larvae and biology of
Glaresis are as yet unknown. Due to their narrow habitat associations, a great number of these species occur in extremely limited geographic areas, and are accordingly imperiled by habitat destruction.
