Description: Body form weakly stellate, overall size, relatively small, armtips rounded.
Abactinal plates flattened to convex (especially in carinal series), round to polygonal in outline. Primary circlet plates enlarged, distinctive. Papular pores single or double, present radially, absent interradially. Peripheral granules polygonal to quadrate, discrete from plate (not flush). Madreporite triangular.
Fasciolar grooves present, shallow. Marginal plates bare, smooth, mildly convex granules absent, Marginal plates wider than long, symmetrically round in cross-section. Superomarginal to inferomarginals correspond roughly 1:1. Penultimate superomarginal plates neither swollen nor elongate and not abutting over mid radius. Fascioles between marginal plates present, relatively well-developed. Superomarginals and inferomarginals 9-12 per interradius (from terminal to terminal), bare, smooth, some specimens with minor surface rugosities. Distalmost superomarginals, more swollen than those interradially, symmetrically round in cross-section. Peripheral accessory granules discrete, (not flush with plate) polygonal to quadrate, rectangular. Terminal plate enlarged, at 1x-2x the size of adjacent superomarginal plates.
Actinal plates, relatively large, angular to polygonal, smooth, bare surface, granules absent. Peripheral granules for actinal plates polygonal to quadrate in shape, Furrow spines 2-5 compressed, but thickened, subambulacrals granular, thickened (similar in thickness to furrow spines). Pedicellariae, when present, in pits, with tong-like valves. Adambulacral plates with straight, outward-facing surface. Adambulacral “divider” oriented vertically, directed proximally.
Color in life is deep-red to orange with yellow highlights between plates.
