Diamesus is a genus of rather large carrion beetle with two species distributed in tropical Asia and Australia. Like other Silphinae, it has an antenna with 11 segments. About 3 or 4 abdominal segments are visible beyond the tip of the elytra. The elytra themselves have longitudinal keels. The type species is Diamesus osculans.[1] The larvae are broad and flat and somewhat cockroach-like (blattiform).[2]
