The dry bark beetles (Bothrideridae) are a small family with about 400 species in 38 genera worldwide. Bothriderids are found in all major zoogeographical regions of the world with the majority of diversity in the Old World tropics. Seven species have been recorded from Germany. The major part of these species is regarded as very rare "urwaldrelikt" species. They are normally found under the bark of dead or dying trees and are commonly associated with wood-boring insects. Many are cylindrical in shape and exhibit morphological adaptations for occupying the tunnels and galleries of wood-boring beetles. Several species are predaceous, other are thought to be mycophagous.
