Species of the genus Tinotus Sharp of America north of Mexico are reviewed. Five species are recognized: T. caviceps Casey, T. imbricatus Casey, T. morion (Gravenhorst), T. pavicornis Casey, and T. trisectus Casey. The genus Tinotus is recorded from Canada for the first time and is represented in the country by two previously unrecorded species: T. morion (Gravenhorst), introduced from the Palearctic region, and T. caviceps Casey, described from Nevada and subsequently reported from California, Idaho, Indiana, Iowa, and Montana. Tinotus morion was previously listed in North America from Connecticut and Nevada (unverified records), but until now it was unknown from Canada. Here it is reported as new for New Brunswick, Quebec, Ontario, Alberta, and British Columbia. Tinotus caviceps is found for the first time in southern Quebec where it probably reaches its northern distribution limit. The following synonymies are established, with the first names being valid: T. caviceps Casey (= T. pallidus Casey), T. imbricatus Casey (=T. amplus Notman, T. brunnipes Notman), T. pavicornis Casey (T. planulus Notman), and T. trisectus Casey (=T. binaries Casey, T. brunneus Casey, and T. lateralis Notman). A new lectotype is designated for T. brunnipes Notman. The lectotype specimens have been dissected and their genital features illustrated. Diagnoses, illustrations, and a key to identify species from America north of Mexico are provided.
