Class: Asteroidea

Image copyrights: Sophie Valtat

Color: Yellowish-orange with the papular areas brown. The actinal plates are reddish-white. The eight plates at the base of each jaw are reddish-yellow and the grooves between the actinal plates are reddish (preserved in formalin).

The body is pentagonal with the arms completely reduced in size. It has distinct marginal plates even in adult stage, well defined triangular pore areas, and no tubercles on the aboral skeletal plates. On the abactinal side there are regular triangular papular areas arranged in hexagons. At the centre of each hexagon there is primary plate with six slender connecting ossicles which separate the six triangles of each hexagon. The primary plates are arranged in very regular series and they lie parallel to the median radial on either side of which three series can be plainly seen. Each triangular area has about 60-90 papulae. Each papular pore is surrounded by 6-8 granules. The papular areas above the superomarginal plates are large, linear and dendritic. The primaiy plates and the trabeculae are covered by small, crowed, polygonal, unequal and sUghtly convex granules. The granules in the papular areas are slender and longer than those present on the abactinal plates. They are in the form of minute tapering spinelcts. Several small, spatulate two jawed slender pedicellariae are present in each papular area. The madreporite is oval in shape and situated at a distance of 20 mm from the centre of the disc. There are 11 or 12 oral spines on the inner row and the outer row consists of four spines swollen and wrinkled at the tip.
