The genus Schwiebea is one of the most speciose in the Acaridae, currently containing 76 nominal species. Of these, fewer than five have had adult and deutonymphal stages positively associated through rearing or collection of pharate instars. None of the type-species of the currently subsumed genus-group names (Schwiebea [s.s.], Megninietta, Troupeauia, Jacotietta) has had these dimorphic stages correlated. In northern lower Michigan, Okabe and OConnor discovered a new species of Schwiebea in fruiting bodies of the fungus, Cantharellus infundibuliformis, which is very similar to the type-species of Schwiebea, S. talpa Oudemans. After rearing this species in the laboratory, we are preparing descriptions of the full ontogeny of this species, including the deutonymph.
