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 centimetre (0.39 in). 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. Ademosynidae has sometimes been synonymized with the older family Permosynidae, even though the latter was established based on fossils of isolated elytra and the former was established based on fossils of complete bodies.

Genera

The family Ademosynidae is restricted to the following six genera and 11 species in Yan, Beutel and Ponomarenko (2017):

The following genera and species are also included in the family according to Fossilworks, but are excluded or not mentioned in Yan, Beutel and Ponomarenko (2017). Some of these species, for instance those of Ademosynoides and those of Ademosyne described by Tillyard and Dunstan, were described from fossils of isolated elytra.
