Original Description Test consists of two or three (?) segments; cephalis quite rough-surfaced, covered with flared, bugle-like tubes or pores, often with an apical horn. Internal cephalic skeletal elements invisible. It is possible that the cephalis may be broken or missing, as the apical part is remarkably ragged externally. Thorax cylindrically spindle-shaped, penetrated by many circular pores regularly longitudinally arranged. Abdomen (?) quite short, broken or ragged, often with three terminal feet. Etymology: The name is derived from the Greek, meaning with a buckler.
