MERISTICS.—Arms = 12–13, R = 161–381 mm, r = 16–22 mm, R/r = 10–17/1, length of gonadal region = 61–95 mm, length of longest arm spine = 9–15 mm.

DIAGNOSIS.—[80.a] Madreporite large, raised; [100.a] madreporite irregular, coarsely channeled; [110.a,b] abactinal disc plates metapaxillar, tumid, irregular; [120.a] abactinal disc plates widely scattered in membrane; [130.a] abactinal disc plates bearing 1–3 very small sharp spinelets; [170] number of arms 12 or 13; [210.a] abactinal arm plates rod-like; [220.a] abactinal arm plates imbricate across arms in raised ridges (costae), costae well spaced, no plates between or beyond costae; [240.a] abactinal arm plates bearing 0–8 small sharp spinelets in a line on ridge of plate; [280.a] marginal plates very small relative to adambulacrals; [290.a] shape of marginals irregular; [300.b] marginals occurring about every 2–3 adambulacrals; [310.a] marginals bearing one moderately long acicular spine; [320.a] adambulacral plates large relative to marginals, higher than long; [330.b] adambulacrals spool-shaped, higher than long, with sharp inner distal prolongation; [340.a] furrow margin straight; [350] number of furrow spines 1–3; [360.a] furrow spines quite small, slender, acute; [370.a] furrow spines on proximal end of adambulacral; [380] number of subambulacral spines 1(2–3); [390.a,b] subambulacral spines moderately large, acicular, sometimes proximal ones slightly capitate; [420.a] ambulacral plates high, forming distinct ridge along arm; [430.a] head of ambulacrals saddle-shaped; [470.a] structure of tubefeet delicate, thin, translucent; [480.a] mouth plates rather small relative to adambulacrals; [490.a] mouth plates T-shaped; [500] number of preoral spines per mouth plate 1; [510.a] preoral spines very long, fine, acicular; [520.a] position of preoral spines adoral; [530] number of lateral oral spines 2 per mouth plate; [540.a] lateral oral spines small, slender, slightly curved, acicular; [550.a] lateral oral spines on oral edge of mouth plates, beneath preoral spines; [560] number of suboral spines per mouth plate 1; [570.a] suboral spines large, acicular; [580.a] position of suboral spines just behind preorals; [620.a,b,c] pedicellariae tiny, abundant on membrane of disc and in irregular bands on membranous part of arms beyond costae, all spines enclosed in fleshy sacs completely covered with pedicellariae; [630.a] all pedicellariae microscopic.
