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.
