Chaetodiadema africanum H.L. Clark, 1925c  

Fig. 26 View FIGURE 26 A –C.

Astropyga radiata: Bell, 1904: 168   –169.

Chaetodiadema africanum H.L. Clark, 1924: 2   –3. Pl. I; H.L. Clark, 1925a: 49 –50; Clark & Courtman-Stock, 1976: 224 –225; Schultz, 2011: 1131, Fig. 1989.

Material examined. MBC-A077778; MBC-A077779; SAMC-A23717.

Identification. Test yellow-greenish; aboral interambulacra naked, v-shaped, blue iridescent spots in live animal, appearing as dark marks in preserved specimen, but yellow on cleaned test.

Global maximum size. Maximum test diameter 45 mm.

Global distribution. Endemic to East coast of South Africa, at 85–325 m depth ( Clark & Courtman-Stock 1976, Schultz 2011).

Remarks. May be mistaken for Astropyga radiata   , but differs in test shape. C. africanum   is flattened orally and aborally; whereas upper side of A. radiata   is more convex. Color also distinguishes the two species, where adult A. radiata   is red with blue spots on naked interambulacra zones and adult C. africanum   pinkish. The genital plates and enlarged madreporite extending into the interambulacral area may also distinguish A. radiata   from C. africanum   .
