This is another Radianthus species popular among marine aquarium hobbyists. It is widely known under the name Heteractis malu, but its valid name is Radianthus malu. See comments under Radianthus crispa for more information on generic names of this and related species. In brief: currently the genus Heteractis contains only one species (Heteractis aurora), and most other species referred to this genus (including Heteractis malu, Heteractis magnifica and Heteractis crispa) - they all actually belong to Radianthus.
