Description: Large slender to moderately inflated stars, R to 13 cm (Holotype R = 12.1), r to 2 cm, R:r 6.5:1 (Figs. 77 & 78); disc small, rays long, slender, often somewhat inflated at base, tapering to slender tips. Abactinal plates (Fig. 79) small, round to oblong, up to three times as long as wide, crowned with 25–50+ short (to 0.2 mm), thorn-tipped spinelets; madreporite small, spinose, located equidistant between anus and disc margin. Marginal widely separated at base of rays; superomarginals approximately two or three times as large as aboral plates, crescent-shaped, set in a distinct, oblique row; intermarginal plates in two series, plates of the first very small (about 1/4 to 1/3 the size of ...
