Members of this tribe are primarily found in forest litter and soil habitats where they function as micro-predators or scavengers.
Brathinus
Brathinus is a genus of rove beetles in the family Staphylinidae, distributed across North America and East Asia (Japan, China). The genus is distinguished from typical staphylinids by its unusually long elytra that cover nearly the entire abdomen, rather than leaving most abdominal segments exposed. Six species are currently recognized, with three described from North America and three from Japan. The genus was established by LeConte in 1852.
