ABSTRACT. The Nearctic species of dance flies of the subgenus Anacrostichus Bezzi, 1909 of the genus Empis Linnaeus, 1758 are reviewed. A total of ten species of the group are recognised from this region including a new species: E. (A.) spaetensis sp.n. (Canada (British Columbia)). In addition, a new synonym is proposed: Empis laevigata Loew, 1864 = Empis lucida Zetterstedt, 1838. All species are redescribed and illustrated. A key to the North American species of Anacrostichus is provided.
KEY WORDS. Diptera, Empididae, Empis, Anacrostichus, dance flies, North America.
