In the present revision we revised 22 species from South America, excluding the following southern South American species: E. borgmeieri Denier, 1935; E. floydwerneri Martinez, 1955; E. franciscana Denier, 1935; E. fulginosa (Oliver, 1795); E. purpureiceps (Berg, 1889);E. rutilifrons Borchmann, 1930; and E. zebra (Dohrn, 1876) because they do not have the diagnostic characters of the group. The species of the E. vittata group from southern South America are: E. bosqi Denier, 1935; E. clericalis (Berg, 1881); E. grammica (Fischer, 1827); E. leopardina (Haag-Rutemberg, 1880); E. luteo-lineata Pic, 1933; E. missionum (Berg, 1881); E. monachica (Berg, 1883); E. rutilifrons Borchmann, 1930; plus two more species E. excavata (Klug, 1825); and E. semivittata (Fairmaire, 1875) until now not included in other groups. We provide a complete diagnosis of the E. vittata group from southern South America, redescribing and illustrating all included species. Detailed descriptions and illustrations of female and male genitalia are presented for the first time for these species. Finally, we provide an identification key for the ten species presently included in the E. vittata group, and update the geographic distribution of each species.
