Note.

See Campbell (1976) for identification. Sepedophilus basalis is listed as occurring in Ontario by Bousquet et al. (2013) and Ontario and Quebec by Newton (2022). However, we have corresponded with these authors and could not determine a published voucher-based source for the records. It is possible the Quebec record came from the historical account by Provancher (1877: 243), although misidentifications with other species were common before the modern revision by Campbell (1976). The inclusion of this species in the Ontario fauna likely came from unpublished data of specimens deposited in the CNC. We here provide voucher data for Sepedophilus basalis , which occurs in Canada, broadly from southern Ontario to southern Quebec.
