Description
Color: Rose red

Size: Distance from the centre of the mouth to the tip of the arm (R) = 21 mm;
Distance from the centre of the mouth to the interradial margin (r) = 7 mm.

Arms five, equal, breadth 8 mm at the base, flat below, somewhat raised at the base above. Abactinal plates around the anus small with minute spinelets, surrounded by a circle of larger elongate plates; a small madreporite close to and outside the circle in interradial position. Rest of the abactinal plates on the disc and proximal midradial areas of the arms irregularly arranged with a notch for the papular pores. Arms slightly keeled midradially in the distal half, midradial series with larger plates and lateral series of smaller plates, slightly imbricating. Papulae scattered on the disc, absent in the interradii, in 6-7 series at the base of the arm, only the middle series on either side reaching beyond two-thirds of the arm length. Superomarginals not distinct, slightly rounded, terminal plates larger and distinct. Inferomarginal plates extending beyond the superomarginals, each with a tuft of 6-8 slender spines. Actinal intermediates in regular series closely packed upto the oral plates leaving no naked areas in the interradii; only the series adjacent to the adambulacrals reaching the tip of the arm, each with a single long slender pointed spine slightly bulged at the base. Oral plate with six marginal spines, the innermost the longest, and a single pointed spine on the actinal surface, rarely two on odd plates. Adambulacrals with four, rarely five, furrow spines and two subambulacral spines.
