Perdita (Epimacrotera) ainsliei Crawford 1932 Comments: Originally described from Sioux City, Iowa (Crawford 1932), this species is also known from New Mexico and a single male was collected by Matthias Buck in the Canadian province of Alberta (Z. Portman, unpublished). It may occur in Minnesota, though the lack of recent records in the midwestern United States suggests it may have declined.
