The following species are newly recorded or described as new in New Brunswick and Canada: Apimela fusciceps (Casey); A. canadensis Klimaszewski & Webster, >sp. n.; and Gyronycha pseudoobscura Klimaszewski & Webster, >sp. n. The genera are defined and the key for species identification is provided. Color habitus images and black and white images of the median lobe of the aedeagus, spermatheca, tergite, and sternite VIII are provided for all species occurring in Canada, and Apimela macella (Erichson), the type species of genus Apimela, and G. valens Casey, the type species of Gyronycha. New or additional habitat data are provided for the species treated in this contribution. The following new synonym is established: Gyronycha lepida Casey, 1911 (NC), is a synonym of G. fusciceps Casey, 1894 (NC).
