Ademosynidae is an extinct family of beetles, known from the Late Triassic to Early Cretaceous. There are at least six genera and 11 species in Ademosynidae. Members of the family were small oval beetles, with a length generally smaller than 1 cm. Characteristics of the family include a pronotum without anterior angles and a rounded anterior margin, and elytra with 9–12 punctate striae. The systematic position of the family within the order Coleoptera is currently uncertain: they can be considered early examples of the suborder Polyphaga, or unusual examples of Archostemata.
