Identification. Test outline ovoid, flat, without frontal notch. Apical disc anteriorly positioned. Peristome kidney-shaped. Aboral primary tubercles large, crenulated and perforated. Oral side flat, phyllodes well-developed, labral plate long, separated from sternal plates by adjacent ambulacral plates, sternal plates short, tubercles with large areoles laterally bordering naked space. Spines long. Red-brownish in color, with partially white spines.

Global maximum size. Maximum test length 75 mm.

Global distribution. East coast of South Africa and Mauritius ( Mortensen 1950; Schultz 2009), at 30–325 m depth

Remarks. Samples identified through this study show that species can be found in shallower waters of 30 m than the previously thought 50 m.
