Classification and/or Status Clypeasteroida; Scutellina; Laganiformes; Rotulidae.

Objective junior synonym of Rotula Schumacher, 1817.
Remarks The name Echinotrochus was first used in Leske (1778: p. 209) where "Echinotrochus rosaceo" appears (only) as translation of Van Phelsum's "Roose topje" in the discussion of Echinodiscus rosaceus. It thus has to be regarded as nomen nudum and the correct authority is Pomel, 1883.
