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.[1][2][3][4] 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.[3]
Genera
