Description The disc is flat, 6 mm diameter. The radial shields are covered. The dorsal surface is covered by skin; primary plates not visible. The ventral interradial surface is with skin. The oral shields are covered in skin. The adoral shields are covered in skin. Bursal slits absent or reduced, not bordered by spines or papillae. The jaw is as wide as long, with one or two, pointed or tapering apical papilla, longer than wide, with thorns. Oral papillae separated by a gap from apical papillae, pointed, thorned. 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, 3–6 times d.d. Dorsal arm plates not visible, covered by skin, without spines/granules. The second ventral arm plates are not visible, covered by skin. Ventral arm plates of the first free segments contiguous or not visible, covered, quadrangular, notched or concave laterally, and 0.9–1.1 times long as wide. Tentacle pores along the arm, with no scales. There are 0–1 arm spines on the first ventral segment, 2–4 on the first free segments. The spines are erect, extending laterally, subequal, and 1–2 times as long as one arm segment, pointed or blunt, cylindrical. There are thorns, in longitudinal series on the surface from the base to the tip of the spine, all along the spine, glassy transparent shaft. Spines also skin partially (at base) or completely covering spine.
