Thiasophila
Thiasophila is a genus of myrmecophilous rove beetles (Staphylinidae: Aleocharinae) that inhabit ant colonies, primarily those of the Formica rufa species group. Species in this genus have evolved specialized adaptations for living among ants, including defensive secretions and morphological plasticity in immature stages. The genus contains at least three European species: T. angulata, T. lohsei, and T. szujeckii, with T. szujeckii being a recently described cryptic species from Poland.
