Erotylidae

Definition

A family of beetles (order Coleoptera, superfamily Cucujoidea) commonly called pleasing fungus beetles, containing over 100 genera in six tribes and ten subfamilies. Members feed primarily on fungal and plant matter, with some species serving as pollinators and others as minor agricultural pests. The family has undergone taxonomic revision, with the current circumscription corresponding to the formerly broader subfamily Erotylinae sensu lato. Diagnostic characters include distinctive coloration patterns, though phylogenetic relationships remain under study due to insufficient morphological analysis of structures such as the metendosternite and penile flagellum.

Etymology

From the genus Erotylus + -idae (family suffix)

Example

The genus Pharaxonotha within Erotylidae includes both beneficial pollinators and economically significant pests, illustrating the family's ecological diversity.

Synonyms

• Pleasing fungus beetles

Related Terms

Usage Notes

The family circumscription has narrowed; older literature may use Erotylidae in a broader sense equivalent to modern Erotylinae sensu lato. Color-based taxonomy has proven unreliable; modern identification requires attention to genitalic and internal skeletal characters that remain understudied. Not to be confused with unrelated fungus-feeding beetle families.
