Description The disc is flat, 17 mm diameter. The radial shields are covered. The dorsal surface is covered by plates, no spines/granules or skin bearing spines/granules, with a visible diameter of 0.25–0.65 mm, seperated; primary plates not visible. Disc spines or granules of one type, cylindrical. The spines are up to 0.1–0.2 mm long, and 0.3–0.7 times high as wide; densely distributed. The ventral interradial surface is with skin. The oral shields are covered in granules or covered in skin. The adoral shields are covered in granules or covered in skin. Bursal slits reduced, not bordered by spines or papillae. The jaw is wider than long, with one or two (tending toward a cluster), pointed or tapering apical papilla, longer than wide. Oral papillae are present along each jaw angle in a series, pointed. The oral tentacle pore is located inside the jaw, with distal oral papilla similar to other oral papillae. The specimen has five arms, unbranched, moniliform, 4–8 times d.d. Dorsal arm plates not visible, covered by skin, with spines/granules, extending the length of the dorsal arm; bands of hooklets. The second ventral arm plates are not visible, with granules. Ventral arm plates of the first free segments not visible, covered. Tentacle pores along the arm, with no scales. There are 0 arm spines on the first ventral segment, 5–7 on the first free segments. The spines are erect, restriced to the ventral surface, subequal, and 0.5–1 times as long as one arm segment, blunt, cylindrical. There are thorns, forming terminal points, on the tip, glassy rough shaft, with hooks.
