— Let G be a connected reductive group defined over a complete local non archimedean field -F, and let G denote its F-valued points. Let (TT, V) be an irreducible admissible representation of G, and let (cr, W) be a representation of a parahoric subgroup P which is trivial on the prounipotent radical U of P. We say that (TT, V) contains (a, W) if, when restricted to P, the cr-isotypic part Vais nontrivial. Assume that ((T, W) is irreducible cuspidal on the finite group of Lie type P / U , and that Vcr 7^ 0. We show that (TT, V) is supercuspidal if and only if P is maximal; in this case TT is compactly induced from the normaliser of P. We then classify supercuspidal representations containing unipotent cuspidal representations, provided G is an inner form of a split adjoint group, following a conjecture of G. Lusztig.
