Zopheridae
The Zopheridae family of beetles has grown considerably in recent years as the members of two other families have been included within its circumscription; these former families are the Monommatidae and the Colydiidae, which are now both included in the Zopheridae as subfamilies or (in the former case) even as tribe of subfamily Zopherinae. Some authors accept up to six subfamilies here, while others merge all except the Colydiinae into the Zopherinae. Over 100 genera are in the redefined family, and hundreds of species worldwide. No common name is used for the new family, though some of the constituent  subfamilies have their own, including the ironclad beetles, and the cylindrical bark beetles. The oldest fossils of the family are "Paleoendeitoma" (subfamily Colydiinae, tribe Synchitini) and "Cretomysteria" from the early Late Cretaceous (Cenomanian) Burmese amber from Myanmar. Genera. These 89 genera belong to the family Zopheridae:
