Appearance

The disc is sparsely covered with sharp spinelets that are often pale, especially at the base. The arm spines are long and uniformly dark, not banded. Some individuals have some upper arm spines conspicuosly expanded at the tip into a club-like shape but other individuals have all arm spines elongate and tapering (Devaney, 1978).
