Acanthocidaris maculicollis: Mortensen, 1928a: 329 –333. Pl. XLIII, Figs 1–2 . Pl. XLIV, Fig. 1 . Pl. LIV, Figs 5–6 . Pl. LXXXIII, Figs 12–15 ; Mortensen, 1932b: 157 –158. Pl. V, Fig. 6 . Pl. XI, Fig. 5 ; Clark & Courtman-Stock, 1976: 214; Filander & Griffiths, 2014: 51. Pl. I, Fig. E.

Acanthocidaris curvatispinis: Schultz, 2011: 875 , Figs 1469–1473 [misidentification].

Material examined. SAMC-A28233.

Identification. Test moderately high, flattened aborally, with circular outline; primary tubercles crenulated. Ocular plates usually insert, apical disc slightly larger than peristome. Primary spines long, longitudinally with reddish bands, collar conspicuously marked with red spots, secondaries loosely packed.

Global maximum size. Maximum test diameter 61 mm.

Global distribution. East coast of South Africa ( Filander & Griffiths 2014), East Indies and South of Japan ( Clark & Courtman-Stock 1976); at 40–225 m depth ( Mortensen 1928a).

Remarks. Based on the single sample from southern KwaZulu-Natal housed at the Iziko Museum. Although, Schultz (2011) reports on Acanthocidaris curvatispinis in the region, this record might be dubious, therefore further investigation is required to confirm A. curvatispinis in South Africa.
