The 31 species of Microctonus Wesmael that occur in North America are taxonomically treated. Six are described as new: M. cappilicrus, M. gouleti, M. passi, M. portalensis, M. rotundatus, and M. sharkeyi. Microctonus zimmermanni Loan is considered a junior synonym of hi. brevipetiolatus (Thomson) and hi. barri Loan is considered a junior synonym of M muesebecki Loan. The European Perilitus alticae Haeselbarth is given the new name hi. haeselbarthi. Microctonus nigri-tus (Provancher) is considered a nomen dubium. A key to the species, a list of hosts, and images are provided.
