Long, cylindrical trunk with prominent angular antero-dorsal hump clearly marked at posterior boundary of neck. Females with longer trunk length than males. Proboscis large, globular, wider than long, with prominent apical organ and sensory pits; hooks in all circles, with discoid roots; anterior hooks all at same level, longer than middle and posterior hooks.
