Material examined. A28211; A23447.

Identification. Test compact, with non-crenulated primary tubercles. Apical disc sunken, small, closely tuberculated, with ocular plates widely exsert, madreporite larger than other genital plates. Peristome larger than apical disc. Primary spines dark brown, granulated with longitudinal ridged tips; secondary spines lighter brown, strongly adpressed, smooth and somewhat fusiform.

Global maximum size. Maximum test diameter 80 mm.

Global distribution. Red Sea and Madagascar to Tonga Islands, from Rui-Kui Islands to Australia; at depth 5–70 m ( Mortensen 1928a; Schultz 2010). East coast region of South Africa ( Filander & Griffiths 2014).

Remarks. Differs from Eucidaris metularia   in spine characteristics, Phyllacanthus imperialis   having long primaries, whereas E. metularia   has short, stout ones.
