Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Historically, Laemophloeidae was treated as a subfamily of Cucujidae, but starting in the middle of the 20th century, most of what had been treated as subfamilies of the Cucujidae were considered to be families.
Most laemophloeids, adults and larvae, are found under bark of dead trees, where they apparently are primarily fungivores, although some genera with adults having subcylindrical bodies (e.g., Leptophloeus, Dysmerus) occur in the galleries of bark beetles (Curculionidae: Scolytinae), upon which they may feed. A few genera, but most particularly Cryptolestes, contain some species that are pests of stored grain products. The most important of these are C. ferrugineus (Stephens), C. pusillus (Schönherr), and C. turcicus (Grouvelle).
Several genera exhibit unusual modifications to male antennae (especially Cryptolestes, Dysmerus, and Microbrontes), with the scape expanded into hook-like or blade-like structures Several other genera (Rhinomalus, Rhinophloeus, and Metaxyphloeus) related to Laemophloeus are atypical in that the adults are rostrate to varying degrees Photographs of most world genera are available at, and most North American species are pictured at,
