Diagnosis

Body strongly stellate (R/r= 3.5–4.5), arms triangular, interradial arcs acute. Abactinal surface with mound-like, abutted plates, outlines round, size and shape largely uniform. Abactinal, marginal, actinal surfaces all covered by continuous granulation. Marginal plates with lateral facing, no spinelets or tubercles on distal superomarginal plate surfaces. Papulae present abactinal, lateral, actinal surfaces. Three, thick, blunt furrow spines, adjacent to two blunt subambulacral spines. Adambulacral surface otherwise covered by granules consistent with those on actinal surface.

Comments

This species differs from Fromia hemiopla, in absence of tubercles or spinelets on the distalmost marginal plates, presence of a more stellate body shape, and a narrower arm abactinal plate field. Indian Ocean specimens of this species were documented by Mah (2018)
