Damages of Gastrallus pubens Fairmaire (Coleoptera: Anobiidae) in a library

Gastrallus pubens Fairmaire (Coleoptera: Anobiidae) was recently found in a library in northern Italy, where 1800 books were located. Aesthetic and structural damages were observed on 4.5% of books, especially the oldest one. The deep galleries on the books were due to the action of larvae while circular holes were made by new-emerged adults. Most of damages were observed near the volume bounds.
