Sternaspis Hope, 1837 Strombodes Gistel, 1857 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.

[2] Oxysternon is a Neotropical genus and most species are native to the Amazon basin or the Guiana Shield in South America.

Only two species are absent from both the Amazon basin and the Guiana Shield: O. pteroderum is restricted to Atlantic Forest in eastern Brazil and the common O. palaemon is found widely in the Cerrado.
