Derodontidae, a family of beetles, part of its own superfamily, [[Derodontoidea]], is commonly called tooth-necked fungus beetles. They are closely related to the [[Bostrichoidea]], of which  the death watch beetles, skin beetles, and powder-post beetles belong to. There are about 10 species in 4 genera in Derodontidae. It is a small beetle, between 2 and 6 mm in length, with spiny margins on their pronotum (part of the thorax)   of which they are named after. The [[Laricobius]], a genus of Derodontidae, doesn't have these spines these spines.

Their antennae are inserted before their small, prominent eyes and have large [[elytra]], (hardened forewings of certain insects, as beetles, forming a protective covering for the posterior or flight wings.) http://dictionary.reference.com/browse/elytra which completely cover the [[abdomen]]. The tooth-necked fungus beetle's legs are moderate for its size, and it is usually brown, brick-red, brownish-red, or brownish-yellow.
