The scutellum is hidden; the metepisterna do not reach the mesocoxal cavities; the tarsi are evidently 5-jointed, the joints of the metatarsi lobed. The internal lamellae of the metacoxae are only detached behind, forming the metacoxal processes; the metasternal wings are narrow; the prosternal process and the prosternum are on the same plane, the prosternal process lanceolate or narrow and sharply pointed; in Neptosternus it is trifid.
