Distribution. Northern Namibia to west coast of South Africa, 18– 117 m.

Remarks. This species was recently described by Natasen-Moodley (2008) from material taken from St. Helena Bay (Western Cape Province, South Africa) between 18– 32 m. The current material satisfies well the description of the type. It ranges from 2–15 mm in length. Juvenile specimens are white in alcohol, whereas the older specimens are uniformly pinkish-brown. Juveniles have more rounded plates in relation to the elongated plates, and the knobs and the spines of the elongated plates are less pronounced. The tube feet deposits are simple and typical. With growth, the rounded plates of the body wall appear to decrease in number, the knobs of the elongated plates become more pronounced, their spines more defined and the tube feet deposits more elaborate.
