Oxysternon is a Neotropical genus of scarab beetles (Scarabaeidae) in the superfamily Scarabaeoidea. It can be distinguished from all other phanaeines and scarabaeine dung beetles by a long, spiniform extension of the anterior angle of the metasternum. Most species vary in color and pattern, and are more commonly found in tones of green, often infused with yellow or coppery highlights. All species appear very smooth or glassy smooth to the unaided eye.

==Taxonomy== ===Nomenclature=== The genus Sternaspis was proposed first by Hope in 1837, but the name was preoccupied and thus invalid. Laporte, writing under the pen name of Le Compte de Castelnau, proposed the genus Oxysternon to include several species of Phanaeus-like species. O. festivum was later designated as the type species.
