Calliaster nazaninae

The species has a flat, stellate body with broad-based, triangular arms that have pointed tips. A dark to black outline is present around the periphery of the abactinal and marginal plates. Abactinal plates are flattened, with spines present only on the proximalmost radial plates and primary circlet. The arm is composed of approximately 3 to 6 fully or partially abutted superomarginal plates beginning about halfway along the arm's length. Superomarginal plates are quadrate in shape and flattened; there are 14 per arm side (28 per interradius). They bear 2 to 4 conical pointed spines on the proximalmost plates, with identical spines present in series along the dorsolateral angle. The actinal area is composed of 1 or 2 incomplete series, limited to the disk region. Furrow spines number 7 to 10, are slender and pointed, and are arranged in a stellate pattern. Subambulacral spines number 2, then 1 distally, and are prominent, thick, with blunt but pointed tips.^[1]

This species is known from off New Caledonia at depths of 150 to 282 meters.^[1]
