Description Body form weakly to strongly stellate, relatively thin relative to Tosia or Pentagonaster. Arm tip, rapidly narrowing, pointed.

Abactinal plates extremely convex, swollen, mostly bare, smooth, round to polygonal in outline. Abactinal surface covered with large, evenly round, spherical granules covering some secondary plate surfaces and plate periphery, especially at lateral contact with superomarginal plate series. Abactinal plates all relatively uniform in size, radial/interradial plates not distinctive, not enlarged. Primary circlet plates sometimes enlarged. Abactinal plates relatively small compared to Tosia or Pentagonaster. Large bivalve-pedicellariae present, commonly bisect abactinal plates. Madreporite polygonal. Double to multiple papular pores present, but absent interradially.

Fasciolar grooves between abactinal plates well-developed. Marginal plates convex, longer than wide, interradially, becoming more wider distally, relatively small compared to Pentagonaster or Tosia, decreasing in size distally. Enlarged bivalve pedicellariae similar to those on abactinal plate surface irregularly present on superomarginal plates. Large, spherical granules, similar to those on abactinal surface form periphery and cover partial superomarginal and inferomarginal surface, especially on lateral marginal plate surface. Granules sometimes distributed patchily over plate surface. Fasciolar grooves between marginal plates, well-developed. Swollen penultimate marginal plates absent. Multiple (3-6) superomarginal plates in contact across midradius adjacent to armtip, becoming more swollen, wider distally.

Actinal plates polygonal, obscured by spherical granules identical to those on abactinal, marginal plate surface, relatively small in size compared to those in Tosia or Pentagonaster. Furrow spines enlarged, relatively few (1-3) in number per plate. Subambulacrals also thickened, granular, becoming indistinguishable from actinal granulation. Adambulacral plate surface facing furrow-straight in outline. Adambulacral “divider” directed horizontally, oriented symmetrically.

Living color described by Mortensen (1933: 243) as a “beautiful red’.
