Charaphloeus adustus
lined flat bark beetle
Charaphloeus adustus is a species of lined flat bark beetle in the family Laemophloeidae, described by LeConte in 1854. The species is known from North America with confirmed records in the Canadian provinces of Manitoba, Ontario, and Québec. Like other members of Laemophloeidae, it is associated with bark habitats. The genus Charaphloeus contains multiple species that are morphologically similar and require careful examination for identification.
Charaphloeus convexulus
lined flat bark beetle
Charaphloeus convexulus is a species of lined flat bark beetle in the family Laemophloeidae, a group of small beetles adapted for living under bark. The species is found in North America, with records from Canada (New Brunswick, Nova Scotia, and Ontario). As with other members of Laemophloeidae, it is presumed to inhabit dead or dying wood where it likely feeds on fungal hyphae or other microorganisms, though specific biological details remain poorly documented.
Charaphloeus flavosignatus
lined flat bark beetle
Charaphloeus flavosignatus is a species of lined flat bark beetle in the family Laemophloeidae, a group characterized by their dorsoventrally flattened bodies adapted for living under bark. The species was described by Schäffer in 1910. It is known from North America. Like other members of its family, it likely inhabits dead or dying wood where it feeds on fungal hyphae.
Charaphloeus unnamed
Charaphloeus unnamed refers to an undescribed species within the genus Charaphloeus, a group of small, flattened beetles in the family Laemophloeidae (lined flat bark beetles). The genus Charaphloeus contains multiple species, some of which remain formally undescribed in scientific literature.

The specific epithet "unnamed" indicates this taxon has been recognized as distinct but has not yet received a formal scientific description or species name.
Cryptolestes
Cryptolestes is a genus of small beetles in the family Laemophloeidae. Several species are economically significant pests of stored products, particularly food grains. The genus includes four particularly notorious species: C. ferrugineus (rusty grain beetle), C. pusilloides, C. pusillus (flat grain beetle), and C. turcicus (flour mill beetle). Species within this genus are morphologically similar and often require examination of genitalia for definitive identification.
Cryptolestes cornutus
Cryptolestes cornutus is a species of flat bark beetle in the family Laemophloeidae. The genus Cryptolestes comprises small, elongate beetles commonly found under bark and in stored products. Many species in this genus are recognized as pests of stored grain and cereal products. The specific epithet 'cornutus' refers to horn-like structures, though detailed morphological descriptions for this particular species are limited in available literature.
Cryptolestes ferrugineus
rusty grain beetle, rust-red grain beetle
Cryptolestes ferrugineus, the rusty grain beetle, is a small lined flat bark beetle and major cosmopolitan pest of stored grain products. Native to Europe, it has achieved worldwide distribution through human commerce, infesting stored cereals, grain products, and dry plant materials. The species is characterized by rapid population growth, strong flight capability for dispersal between storage facilities, and cryptic behavior hiding in cracks and crevices. Its economic impact stems from direct feeding damage to grain germ and endosperm, contamination of products, and resistance to some insecticides.
Cryptolestes punctatus
Cryptolestes punctatus is a species of lined flat bark beetle in the family Laemophloeidae. It is native to North America, with distribution records from Canada (Ontario) and the United States. The species was first described by LeConte in 1854. As a member of Laemophloeidae, it belongs to a family of small, flattened beetles commonly associated with dead or decaying wood and stored products.
Dysmerus
Dysmerus is a genus of small beetles in the family Laemophloeidae, comprising 15 species distributed across the New World from the southeastern United States to Bolivia and the West Indies. The genus remained monotypic for over a century until a 2025 revision resurrected two synonymized species and described 12 new species. Males possess a grotesquely modified antennal scape of unknown function, a diagnostic feature of the genus. These beetles are rarely encountered, though adults occasionally come to light at night.
Dysmerus basalis
Dysmerus basalis is a species of lined flat bark beetle in the family Laemophloeidae, described by Casey in 1884. It belongs to a family of small beetles commonly associated with dead or decaying wood, where they feed on fungal hyphae. The species has been documented in North America. Like other members of Laemophloeidae, it is likely adapted to life under bark, though specific biological details remain poorly documented.
Laemophloeus biguttatus
Two-spotted Flat Bark Beetle
Laemophloeus biguttatus is a species of lined flat bark beetle in the family Laemophloeidae. The species is distributed across Central America and North America, with records extending to British Columbia.

Lathropus rhabdophloeoides
Lathropus rhabdophloeoides is a species of small, flattened beetle in the family Laemophloeidae, commonly known as lined flat bark beetles. Species in this genus are associated with dead or decaying wood and bark, where they inhabit the concealed spaces beneath bark surfaces. The specific epithet 'rhabdophloeoides' suggests a resemblance to the genus Rhabdophloeus, a related laemophloeid genus. Like other members of Laemophloeidae, this species is likely cryptic in habit and difficult to detect without specialized collecting methods.
