A general term for insects belonging to the family Pselaphidae in the order Coleoptera. As their English name, ant-loving beetles, suggests, they are known to be ant-loving. All are small, with body lengths between 0.5 and 4 mm. They are reddish brown to dark brown in color, with extremely short elytra and large, exposed abdomens. Nearly 5,000 species are known from around the world, and about 170 species from Japan, but only a few groups are related to ants. The majority of species live in fallen leaves or soil, and those that prefer special environments include those that live on beaches, in sandy areas, in caves, as well as in ant nests and bird nests.
