REMARK

According to Perrier (1869; 1875), the two individuals collected by Péron and Lesueur in Mauritius in 1803 belong to two species that differ, among other characters, by the presence ( D. cylindricus ) or absence of enlarged granules on the central part of abactinal plates. He created the species Ophidiaster purpureus Perrier, 1869 (see further under that species) to accommodate the second individual.
