Abactinal plate surfaces completely smooth and bare with no surficial accessories. Individual plates with rounded, quadrate to polygonal granules, 15–40, mostly 20–30, evenly spaced around edge, flush with abactinal surface. Granules approximately 1/4 of distance of plate diameter plus peripheral granules. Madreporite irregular in shape, nearly flat, sulci strongly developed, flanked by four plates and their peripheral granules. Papular pores weakly present around radial regions, but no papulae clearly observed. No pedicellariae observed.
