Three acarine parasites of Stenolophus spp are described from Michigan. Eutarsopolipus elzingai Husband (Acari: Podapolipidae), previously known from eastern Kansas, Eutarsopolipus brevichelus Husband and Husband, with one Michigan record, and Crotalomorpha camini Lindquist and Krantz (Acari: Crotalomorphidae), previously known from Kansas, Nebraska, Arkansas and Oklahoma, are widely distributed in Michigan as subelytral parasites of Stenolophus comma (Fabricius) (Coleoptera: Carabidae) and Stenolophus lecontei (Chaudoir), the seed corn beetle. Eutarsopolipus elzingai and E. brevichelus may occur occasionally on the same host beetle.
