Anobiopsis
Anobiopsis is a genus of beetles in the family Ptinidae (formerly Anobiidae), described by Fall in 1905. The genus placement has been subject to taxonomic revision, with some sources placing it in Anobiidae and others in Ptinidae following modern family-level reclassification. No observations of this genus have been recorded in iNaturalist.
Falsogastrallus
Falsogastrallus is a genus of small anobiid beetles in the family Ptinidae, established by Pic in 1914. The genus contains at least three described species, with F. sauteri documented as a significant pest of books and library materials in Taiwan. Adults are minute (1.5–3.5 mm), reddish brown to dark brown, with dense grayish pubescence. Larvae are C-shaped borers that tunnel through book hardcovers, particularly cardboard edges, and construct frass walls for pupation.
Lasioderma
cigarette beetles, tobacco beetles
Lasioderma is a genus of small beetles in the family Ptinidae, containing over 50 species as of 1990. The genus is best known for Lasioderma serricorne, commonly called the cigarette beetle or tobacco beetle, a major cosmopolitan pest of stored products. Members of this genus are associated with dried plant materials and have become distributed globally through human commerce. The genus has been variously classified in Anobiidae or Ptinidae depending on taxonomic treatment.
Lasioderma serricorne
cigarette beetle, tobacco beetle, cigar beetle, paprika beetle, tow bug, tobacco borer, cheroot beetle
Lasioderma serricorne is a small stored-product pest beetle, 2–3 mm in length, with a cosmopolitan distribution resulting from human commerce. It is distinguished from similar anobiid beetles by its uniformly serrated antennae lacking a terminal club, flatter thorax profile, and smooth elytra without grooves. The species has a remarkably broad diet, infesting tobacco, cereals, dried fruits, spices, and herbarium specimens. It possesses a mutualistic relationship with yeast-like symbionts (Symbiotaphrina spp.) that assist in protein metabolism and enable survival on nutritionally poor substrates. Strong flight capability and attraction to UV light facilitate its spread and monitoring.
