Radial shields are small, subtriangular, almost as wide as long. Arm combs visible under the radial shields; with five short block-like arm-comb spinelets, not continuous on dorsal midline.

Oral shield approx. as long as wide, subpentagonal, with somewhat concave proximal margins, a convex distal margin, and with lateral margins slightly constricted in the middle, where the genital slit begins. Adoral shields touching proximally, with a similar width all along, and separating the oral shield from the first lateral arm plates. Genital slits run from the middle of the oral shield to the disc margin, bordered by a continuous row of block-like genital papillae that continues dorsally as an arm-comb.

Lateral arm plates bear three short (less than a third of the length of the arm segment) arm spines from the third arm segment; two are located ventrally, very close together, and one located dorsally, approx. halfway through the lateral arm plate; first arm segment bears two arm spines, the second two or three spines. Ventral arm plate trapezoidal, wider than long, only touching the preceding plate only on first three arm segments, after which they are separated by the lateral arm plates and become fan-shaped to rhomboidal, more than twice as wide as long, with pointed proximal edge and rounded distal margin. Towards the distal end of the arms, the second lowest spine is modified into a hyaline hooklet (Fig.
