The purpose of this application, under Article 23.9.5 of the Code, is to conserve the specific names Scarabaeus ferrugineusOlivier, 1789 (currently Metacatharsius ferrugineus) (Scarabaeidae) and Scarabaeus ferrugineusPalisot de Beauvois, 1809 (currently Bradycinetulus ferrugineus) (Geotrupidae). Although Scarabaeus ferrugineusOlivier, 1789 and Scarabaeus ferrugineusPalisot de Beauvois, 1809 are primary homonyms, they have not been treated as congeneric for almost 180 years and were both transferred out of the genus Scarabaeus Linnaeus, 1758 by 1845. Both names have been treated as valid since they were proposed. It is proposed that Scarabaeus ferrugineusPalisot de Beauvois, 1809 be conserved by ruling that it is not invalid by reason of being a junior homonym of Scarabaeus ferrugineusOlivier, 1789.
