Luzula sylvatica, Bunderbos
front spiracula, dorsal and lateral
cephalic skeleton and mandible
rear spiraculum with three papillae; one is strongly elongated, the two other are bent around the base of the first one; the right picture shows a detail that is shared by most (all?) Cerodontha‘s: a narrow fontal keel with a seam of stiff hairs.
