dc.description.abstractThis study is intended as a collective standardization of descriptions and illustrations of the species of Bezzia in the Nearctic Region. Forty-three species are reviewed, 14 of which are new. Two species are thought to be junior synonyms. A new subgeneric name, Aspinabezzia, is proposed for the already occupied Probezzia of the authors. A key to the adults is presented. When possible, both sexes are illustrated. Including types, approximately 5,000 specimens have been examined. The specimens are both pinned and dissected, mounted on microscope slides. The specimens were borrowed largely from two collections, the U.S. National Collection and the Canadian National Collection. Type specimens were borrowed from several other collections. Numerical data is presented concerning measurements and ratios of the antenna, palp, length-width- costa-R₁-and last costal segment of the wing, tarsi, and the female spermathecae. The subgeneric groupings are discussed. Four subgenera are recognized: Pseudobezzia, Bezzia s. str., Aspinabezzia n. subgen., and Phaenobezzia.en
