Derodontidae is a family of beetles, in its own superfamily, Derodontoidea, sometimes known as tooth-necked fungus beetles. There are 38 species in 4 genera and 3 subfamilies. Beetles of this family are small, between 2 and 6 mm in length, with spiny margins on their pronotum (part of the thorax) that give them their name. The genus, Laricobius, lacks these spines. They have two ocelli on the top of their heads.
