The Osorini are a tribe of beetles in the family Staphylinidae, the rove beetles. These beetles are typically small to medium-sized and are often found in decaying organic matter, under bark, or within leaf litter, where they play important roles in decomposition and nutrient cycling. Unlike many other rove beetles, Osoriinae are less predatory and more frequently associated with fungal material, detritus, or symbiotic relationships with social insects like ants and termites.
