Taxonomic placement
The -level classification of this group has been unstable. Ctenobium has been placed in Anobiidae in older literature and some current databases (e.g., GBIF), but recent phylogenetic work and iNaturalist recognize Ptinidae as the valid family name, with Anobiinae as a . This reflects ongoing revision of the Bostrichoidea superfamily.
