Distribution & Ecology: Society (Tahiti?); Tuamotu (Nukutipipi) - Marine; Shoreline to 10 m; Hard bottom.

Regional Records: Atergatis limbatus - ? Heller, 1865: 8 (Tahiti). - Platypodia granulosa - ? Pesta, 1913: 41 (Tahiti). - Forest & Guinot, 1962: 62 (Biogeography "Tahiti-Tuamotu"). - Serène, 1984: 159 (Syn. ). - Guinot, 1985: 451 (List). - Merschardt-Salvat, 1991: 89 (Nukutipipi). - Poupin, 1996a: 47 (Checklist). - Not Lophactea granulosa - Nobili, 1907: 388 ("Rikitea" = Mangareva, Marutea). - Not Platypodia granulosa - Forest & Guinot, 1961: 51 (Mangareva) - These two references = Platypodia pseudogranulosa sp. nov. in Serène (1984: 159; cf. Remark) - Synonyms - Atergatis limbatus (H. Milne Edwards, 1834). - Remark: Serène (1984: 159), for the description of Platypodia pseudogranulosa, closely related to P. granulosa, does not mention Heller's (1865) and Pesta's (1913) references, neither under P. granulosa, nor under P. pseudogranulosa. Thus we place these two references under both species, with uncertainty.
