Colydiinae is a subfamily of beetles, commonly known as cylindrical bark beetles. They have been treated historically as a family Colydiidae, but have been moved into the Zopheridae, where they constitute the bulk of the diversity of the newly expanded family, with about 140 genera worldwide. They are diverse for example in the Australian region, from where about 35 genera are known; in Europe, though, only 20 genera are found and many of these only with few species.
Cryptolestes is a genus of beetles in the family Laemophloeidae. Several species are known as economically important pests of stored products, especially food grains. The four most notorious species are Cryptolestes ferrugineus, Cryptolestes pusilloides, Cryptolestes pusillus, and Cryptolestes turcicus. C. capensis, C. klapperichi, and C. ugandae are less widespread pests. Species in this genus can be hard to distinguish from one another, and definitive identification often requires close examination of the genitalia.
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.
Silvanidae, "silvan flat bark beetles", is a family of beetles in the superfamily Cucujoidea, consisting of 68 described genera and about 500 described species. The family is represented on all continents except Antarctica, and is most diverse at both the generic and species levels in the Old World tropics.
Biphyllus is a genus of beetles in the family Biphyllidae, containing the following species:
Gannes is a genus of beetles in the family Laemophloeidae, containing the following species:
Laemophloeus is a genus of beetles; it is the type genus of the family Laemophloeidae. The genus has been almost completely reviewed in modern times.
Lathropus is a genus of beetles in the family Laemophloeidae. It has been the subject of recent taxonomic study. Lathropus species are minute (<2mm) flattened beetles with short, clubbed antennae, closed mesocoxal cavities, extremely dense surface sculpture, and dorsal pubescence composed of bifurcate setae. Currently recognized valid species are:

Passandrophloeus is a genus of beetles in the family Laemophloeidae, containing the following species:
Placonotus is a genus of beetles in the family Laemophloeidae. There are 40 currently recognized species, known from all continents except Antarctica. Placonotus species are small (~2mm), elongate, flattened beetles, characterized by long filiform antennae, presence of a frontoclypeal suture, open anterior coxal cavities, and broadly rounded intercoxal process of abdominal ventrite III. Males have the 8th abdominal segment modified to form claspers used during mating. Adults and larvae are found under dead bark, where they feed on fungi. Currently recognized species are:
Planolestes is a genus of beetles in the family Laemophloeidae, containing the following species:
Xylophloeus is a genus of beetles in the family Laemophloeidae, containing the following species:
Pediacus is the largest genus in the family Cucujidae of flat bark beetles. It contains 31 currently recognized species. Pediacus adults are relatively small (2.7-7.0mm), flattened brownish beetles with no or very small temples, and short antennae with a distinct club. Male genitalia are inverted and possess a short flagellum.
Brachypterus is a genus of short-winged flower beetles in the family Kateretidae. There are about 18 described species in Brachypterus.
