Weakly stellate/pentagonal body form. Bare patches on the superomarginal plates absent. Body surface completely covered by soft granular tegument with no bare spots on marginal plates. When underlying tegument has been removed, abactinal and marginal surface with glassy nodules (also called embossed crystalline bodies). Fifteen to sixteen marginal plates present per interradius (arm tip to arm tip).

Abactinal surface covered by granulate tegument which covers plates and spaces between them. Granules eight to 10 along a 1.0 mm line with coarser granules present between abactinal plates and around papular pores. Abactinal plates round to polygonal, mostly homogeneous in size with smaller more irregularly shaped plates present adjacent to superomarginal contact (

B). Abactinal plates extend for approximately 50% of arm distance tapering out as superomarginals abut over midline. Abactinal plates relatively large, approximately three to five present across arm base. Most carinal plates are circular in outline with some more distal plates becoming more oval shaped to irregular shaped (

separate granulation present around plate periphery. Individual plates when denuded show 10 to 80 crystalline bosses embedded in plate surface in evenly arranged ordered patterns. Some individuals display more lobate crystalline structures rather than discrete round bosses. Each interradial region with discrete depression present adjacent to midline interradius; paired plates present in each interradius around this midline. Papulae present radially, absent interradially. Six papular pores present around each plate, each pore with two to four, mostly three eye drop shaped granules present. These papular granules about three to five times the size of the granules present on the abactinal surface. Madreporite round to triangular in shape, flanked by three large plates in most individuals observed.
