Erotylidae, or the pleasing fungus beetles, is a family of beetles containing over 100 genera. In the present circumscription, it includes the subfamilies Dacninae, Encaustinae, Erotylinae, Megalodacninae, and Tritominae. In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition sensu lato. They feed on plant and fungal matter; some are important pollinators, while a few have gained notoriety as pests of some significance. Sometimes, useful and harmful species are found in one genus, e.g. Pharaxonotha. Most pleasing fungus beetles, however, are inoffensive animals of little significance to humans.

Prionoceridae is a small family of beetles, in the suborder Polyphaga. The form a group within the cleroid beetles and were formerly treated as a subfamily Prionocerinae within the family Melyridae. Very little is known of their life history but most species are pollen feeders as adults and occur in large numbers during spring or the host flowering season. Larvae are predatory or feed on decomposing wood.

Orthocis is a genus of tree-fungus beetles in the family Ciidae.
Omalisidae are a very small family of beetles within the superfamily Elateroidea. Members of this beetle family have bioluminescent organs on the larvae. The most recent evidence indicates they are the sister group to a clade comprising the families Rhagophthalmidae and Phengodidae.
