Carpet, Powderpost, and Deathwatch Beetles
is a superfamily of within the infraorder Bostrichiformia. It encompasses several including (powder-post and horned beetles), (), Endecatomidae, and (death-watch and ). Members are predominantly associated with dry and exhibit diverse ecological roles ranging from wood-boring to scavenging on dried matter. The superfamily is united by modified cryptonephridism, male structure, and larval mandibular lacking a mola.

Mite associations
specialized of Winterschmidtiidae . Two new , Bostrichiella and Xylacarus, have been described from Xylobiops basilaris, Amphicerus bicaudatus, and A. cornutus in the Eastern United States, indicating complex phoretic or parasitic relationships between these beetles and astigmatid mites.
