Description The disc is flat, 28 mm diameter. The radial shields are covered or narrow, straight-sided, contiguous proximally, divergent distally; 7 times long as wide, and length 0.5 times d.d. 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 extend from the oral shield to the disc margin, not bordered by spines or papillae. The jaw is longer than wide or as wide as long, with one (partially covered or obscurred by skin), pointed or tapering apical papilla, as wide as long. Oral papillae absent. The oral tentacle pore is located out of the jaw on top of the ventral disc, with no scales. The specimen has five arms, unbranched, moniliform, 11–16 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 not visible, covered. Tentacle pores along the arm, with no scales. There are 0 arm spines on the first ventral segment, 2 on the first free segments. The spines are erect, restriced to the ventral surface, longest ventrally, and 0.5–1.5 times as long as one arm segment, blunt, flattened.
