dd, is pentagonal. The disk plates are numerous, somewhat obscured by thin wrinkled skin when dried, extending across the first 1–3 arm segments, substituting for the dorsal arm plates. Radial shields are very small irregular plates, similar in size to disk scales, placed at the edge of the disk and scarcely visible. The whole dorsal side of the disk is devoid of spinelets. The interradii are slightly swollen. Each jaw bears apically a cluster of 4–6 spiniform teeth or apical papillae. The 2–6 lateral oral papillae together with the adoral shield papillae are placed along both edges of a jaw in a characteristic, slightly curved row around the second tentacle pore. The adoral shield papillae are long, slightly flattened or rounded, similar in size and shape to the arm spines,

number in most interradii. There is a distinct gap between adoral papillae and apical papillae. Between lateral oral papillae and second tentacle pore the jaws form an indistinct rectangular border, which is superficially similar to the blockshaped oral papillae. Beyond this border deeper on the jaws there is small triangular papilla, not evident in all radii. Numerous spiniform teeth are distributed somewhat irregularly. There are approximately 10–12 teeth (including apical papillae) on each dental plate. The oral shield is wide, with straight or slightly convex distal edge, as long as wide, completely separated from the first lateral arm plate by the adoral shields. The madreporic oral shield has a conspicuous swollen oval area occupying the distal portion. The adoral shield is poorly developed, laterally having a narrow wing, widely adjoining the arm, rapidly tapering towards to the midline of the jaws, thus retaining only a narrow inconspicuous bar between the jaws and oral shield. Genital slits are long furrows opening widely proximally, not supported by genital plates.

. On all arms the most proximal dorsal plates are absent for two segments. The dorsal arm plates are well developed but rather small, triangular, well separated on all segments (for about half of the length of the dorsal arm plate proximally and length of the dorsal plate distally). On most proximal segments the dorsal arm plates are somewhat irregular, and have traces of fusion from several pieces and additional small plate distally. All dorsal arm plates have pointed proximal and convex distal edges. Arms have weakly developed nodes, but arm spine articulations are placed on lateral plates without forming an elevation. Laterally between two adjacent lateral plates there is a narrow space of uncovered soft tissue. There are two spines on the first arm segment, three to four on most proximal segments under the disk, five on the proximal free segments, and distally four to three spines. The first dorsal spine is slightly longer than the other ones proximally and medially. Spines are slightly flattened to round, hollow, pointed apically. There are no hook-shaped spines. The first ventral arm plate is broadly triangular, the second has straight distal and proximal edges; further ventral arm plates have a characteristic pole-axe shape throughout most of the arm length, with an almost straight proximal and slightly convex distal edge. Ventral plates throughout the length of the arm are contiguous. The tentacle pores are large throughout the entire arm length. Basally on the parts of the lateral plate encircling the tentacle pores, there are two long, subequal, flattened, pointed tentacle scales, only slightly shorter than the adjacent arm spines. Two tentacle scales persist for at least the three most proximal segments. On most arm segments there is one tentacle scale. Distally the tentacle scale gradually decreases in size. The tentacle scales are shorter than arm spines, but conspicuous and capable of covering the whole tentacle pore. Many of the tentacle scales are broken or have fallen off. There are no tentacle scales on the ventral arm plates.
