Since Auperia Jacquelin-Duval, 1857 was established as an unnecessary replacement name for Euparia Le Peletier de Saint-Fargeau and Serville, 1828, both names are objective synonyms with Euparia being valid. The type species of both genera is Euparia castanea Le Peletier de Saint-Fargeau and Serville, 1828. Dellacasa's later fixation of Scarabaeus stercorator F., 1775 as type species for Auperia is invalid. Stebnicka's later fixation of Auperia denominata Chevrolat, 1864 as type species for “Auperia Chevrolat” is invalid because Chevrolat did not introduce a new name but just referred to Jacquelin-Duval's Auperia. Since Stebnicka synonymized the type species of Odontolytes Kozhantshikov, 1916, O. andamanensis Kozhantshikov, with a species of Phalangochaeta Martínez, 1952, Odontolytes becomes the valid name for Auperia sensu Stebnicka. Consequently, 18 species are transferred from Auperia sensu Stebnicka to Odontolytes which now contains 19 species.
