          Dufourea Lepeletier is the only representative of the subfamily Rophitinae in Canada. An illustrated key to females and males of the eight Canadian species is provided, and each is described; the male of D. fimbriata, and females of D. holocyanea and D. maura are described for the first time. Most Dufourea are floral specialists, so their presence within habitats is determined by that of their host. Floral hosts and known distributions of Dufourea in Canada are provided.
