The genus Trichodesma is revised for America north of Mexico, and seven new species are described: Trichodesma brattaini Schnepp, new species, Trichodesma concinnum Schnepp, new species, Trichodesma cornumaculatum Schnepp, new species, Trichodesma rileyi Schnepp, new species, Trichodesma tachycardia Schnepp, new species, Trichodesma taediosum Schnepp, new species, and Trichodesma whitei Schnepp, new species. Two new synonyms are proposed: Trichodesma fuliginosum White as a new junior synonym of Trichodesma sordidum Horn and Trichodesma pratti Fisher as a new junior synonym of Trichodesma gibbosum (Say), bringing the total number of US and Canadian species to 14. Lectotypes are designated for Trichodesma cristatum (Casey), Trichodesma klagesi Fall, Trichodesma pratti Fisher, and Trichodesma pulchellum Schaeffer. The species are figured, described or redescribed, and maps and a key to species are provided. Information is provided for two closely related genera and North American species, Anobiopsis sericans Fall and Nicobium castaneum (Olivier).
