The dorsal radii are almost devoid of tube feet, each radius with single radial tube foot present close to anterior end of body, and next to anus. These are cylindrical and considerably smaller than those on the sole. Likewise, a single tube foot is also present in each of the ventrolateral radii close to anterior end of body. Somewhat distanced from anterior end (1.6–1.7 mm in the current specimens), ventral sole extends to posterior end of body (

Brooding period includes at least the beginning of April. The only known female has its gonad tubules filled with juveniles, which are all at about the same developmental stage. The juveniles are about 1.2 mm long. The body is cylindrical to deformed due to packing within the gonad tubules. There are at least eight tentacles of about the same size, all retracted. No tube feet were detected and the body wall is covered by a layer of wheel-like baskets, which are also present in the adults.
