'''''Pediacus''''' is the largest [genus](/source/genus) in the family [Cucujidae](/source/Cucujidae) of flat bark beetles. It contains 31 currently recognized species.<ref>John W. M. Marris and Adam Ślipiński. 2014. A revision of the ''Pediacus'' Shuckard 1839 (Coleoptera: Cucujidae) of Asia and Australasia. Zootaxa 3754(1): 32-58.</ref><ref>Michael C. Thomas. 2004. A revision of ''Pediacus'' Shuckard (Coleoptera: Cucujidae) for America north of Mexico, with notes on other species. Insecta Mundi 17: 157-177 (2003).</ref> ''Pediacus'' adults are relatively small (2.7-7.0{{Spaces}}mm), flattened brownish beetles with no or very small temples, and short [antennae](/source/Antennae_(biology)) with a distinct club. Male genitalia are inverted and possess a short flagellum.

==Taxonomy==

The genus is [Holarctic](/source/Holarctic) in distribution, but extends south as far as [Guatemala](/source/Guatemala) in the Western Hemisphere, generally at high altitudes, and into [Australia](/source/Australia) in the Eastern Hemisphere. Adults and larvae are found under dead bark;  frequently that of [conifers](/source/conifers) in North America. They are thought to be predaceous. Most of the world fauna of ''Pediacus'' has been revised recently and the genus is relatively well-known taxonomically. Included species are:

In addition to the extant species, a single fossil species, ''Pediacus periclitans'' Scudder, has been described from the Eocene deposits at [Florissant, Colorado](/source/Florissant_Fossil_Beds_National_Monument). Its assignment to ''Pediacus'' has been questioned.
