The Cucujidae, "flat bark beetles," are a family of distinctively flat beetles found worldwide under the bark of dead trees. The family has received considerable taxonomic attention in recent years and now consists of 70 species distributed in five genera. It was indicated Cucujus species are scavengers, only feeding on pupae and larvae of other insects and on other subcortical beetles such as their own. Since the Cucujidae prey on larvae of potentially tree damaging beetles that spread fungal diseases, they are considered to be beneficial to the health of living trees.
Cucujoidea is a superfamily of beetles. This group formerly included all of the families now included in the superfamily Coccinelloidea. They include some fungus beetles and a diversity of lineages of "bark beetles" unrelated to the "true" bark beetles (Scolytinae), which are weevils.
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.
Dysmerus is a genus of beetles in the family Laemophloeidae. Restricted to the New World, until recently Dysmerus included only the type species, D. basalis, described from Florida in the late 19th century. A recent revision resurrected two incorrectly synonymized species and recognized an additional 12 new species, so that the genus currently contains 15 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:
Microbrontes is a genus of beetles in the family Laemophloeidae, containing the following species:
Rhinolaemus is a genus of beetles in the family Laemophloeidae. Until recently, the genus included only Rhinolaemus maculatus, known from a single specimen collected almost 100 years ago in Fiji. A recent revision, based on newer collections, resulted in the description of a new species from Niue Island, and transferral of a third species from Laemophloeus from Fiji and other island groups.
Cryptolestes turcicus, the flour mill beetle, is a species of lined flat bark beetle in the family Laemophloeidae. It is found in North America and Europe.
Pediacus depressus is a species of flat bark beetle in the family Cucujidae. It is found in Europe and Northern Asia.
Pediacus ommatodon is a species of flat bark beetle in the family Cucujidae. It is found in North America.
Pediacus subglaber is a species of flat bark beetle in the family Cucujidae. It is found in North America.
Pediacus stephani is a species of flat bark beetle in the family Cucujidae. It is found in North America.
Pediacus andrewsi is a species of flat bark beetle in the family Cucujidae. It is found in North America.
Cryptolestes punctatus is a species of lined flat bark beetle in the family Laemophloeidae. It is found in North America.
Oryzaephilus acuminatus, is a species of silvan flat bark beetle native to India and Sri Lanka.
Silvanoprus longicollis, is a species of silvan flat bark beetle found in India, Sri Lanka, Malaysia, Java, China, Japan, Madagascar and East Africa.
Silvanus lewisi, sometimes known as Asian silvanid beetle, is a species of silvan flat bark beetle found throughout the Oriental region and introduced to many parts of the world.
