The Cucujidae is a small family of characteristically strongly flattened beetles, consisting of four described genera: Cucujus, Palaestes, Pediacus and Platisus. We present an overview of the world cucujid fauna, its biology and biogeography. The Australian fauna is discussed, including the first species of Pediacus from the region, which was recently-described, and current taxonomic research on Platisus
