Döderlein 1910: 249 (as Fromia) H.L. Clark 1923: 276; Mortensen 1933: 247; A.M. Clark & Courtman-Stock 1976: 69; Jones 2008: 176–177; Branch et al. 2010: 226; King & Fraser 2014: 340–341 (as Austrofromia)
Diagnosis. A species of Fromia characterized by well-developed, mound-like plates which rise above the body surface (Fig. 14B), especially along the disk and radial regions along the arm. Surface, marginal and actinal surface covered by coarse, continuous granulation. Marginal plates only weakly convex, round to quadrate in outline (Fig. 14A, B. Furrow spines blunt, two per plate with a single row of two blunt, subambulacral spines followed by a second irregular series of two or three blunt spines which are only about half the height of the other subambulacrals (Fig. 14D). Papulae extend from abactinal to actinal surface.
Comments. Fromia schulzei was placed into the genus Austrofromia by H.L. Clark (1923) to accommodate two species, the Australian Fromia polypora and the South African Fromia schulzei. Fromia polypora also occurs in the Indian Ocean, on the west side of Australia.
Rowe (1988) synonymized Austrofromia with Fromia without explanation. H.L. Clark’s (1923) original criterion for establishing Austrofromia seems based on the distinctly coarse granulation of the two species included. There seems to be at least some character justification for separation of Fromia polypora and Fromia schulzei as related taxa, however, treatment of these concepts is beyond the scope of this treatment and, for now, I retain Rowe & Gates’ (1995) treatment of Austrofromia as a synonym as a more conservative taxonomic measure, but future assessments will be required.
Specimens observed herein represent the first occurrence of Fromia schultzei outside of South African waters. Individuals studied were consistent with specimen descriptions as outlined by Clark & Courtman-Stock (1976).
Occurrence. False Bay and south coast of South Africa, Madagascar 4– 30 m.
