This is a myrmecophilous genus of Staphylinidae with 89 species. . Adult and immature Batrisodes are generalist predators/ myrmecophiles that inhabit tree holes, forest litter, rotten wood, caves, and are occasionally found in the presence of ants (some species are obligate myrmecophiles). While poorly known at the level of species, Batrisodes is one of the most studied genera within Pselaphinae in terms of biology, largely due to the work of Luigi De Marzo and Orlando Park.
