Abstract

A new species of podapolipid mite from Michigan, Eutarsoplipus davidsani (Acari: Podapolipidae) is described, illustrated and compared with related species of Eutarsopolipus in the Myzus group. Eutarsopolipus davidsani is an ectoparasite of Chlaenius sericeus (Coleoptera: Carabidae). Keys to genera and groups of podapolipid mite parasites of Carabidae and keys to 11 species in the Myzus group of Eutarsopolipus are provided. The male stage of E. regenfussi Husband and Swihart 1986 is redescribed from specimens taken from the type host, Chlaenius pennsylvanicus
