Megaceras Hope, 1837

[18 species and 2 additional subspecies]. Hope (1837) originally fixed Scarabaeus chorinaeus Fabricius, 1775 as the type species of Megaceras but that species is currently considered a junior synonym of Scarabaeus pan Fabricius, 1775 in the genus Enema Hope, 1837 . Scarabaeus chorinaeus Olivier, 1789, considered as a member of Megaceras and sometimes its type species, is not an available name (Bouchard et al. 2024). An application to the Commission is necessary to fix one of the approximately 20 nominal species currently included in Megaceras Hope (e.g., Scarabaeus jason Fabricius, 1775) as the type species of Megaceras Hope, 1837 . Note: Burmeister (1847) incorrectly spelt Megaceras as “ Megacerus ”.
