Remarks | Tornquist (1908, p. 408) cites "Engelia amalthei Qu[enstedt] sp." as type. If the ambulacral plating is correctly reported this taxon differs from all other Lower Jurassic species described to date. Mortensen (1932, p. 180) states this taxon is based on the ambulacrum of Cidaris laqueata Quenstedt and the interambulacral plates of a Cidaris [=Miocidaris] amalthei Quenstedt. Lambert & Thiery took C. amalthei as genotype. Tornquist, A. 1908. Die Diadematoiden des Wurttembergischen Lias.
