Panniericidaris Vadet, 1991, p. 129

Diagnostic Features	Known only from test fragments and isolated spines. Interambulacral plates wide with confluent oval areoles on ambital and adoral surfaces. Primary tubercle perforate and crenulate. Scrobicular circles not differentiated. Adradial and interradial bands of heterogeneous tuberculation. Associated spines in same bed slender and cylindrical without continuous cortex. Scattered small pustules over the surface.
Distribution	Lower Jurassic (Hettangian-Pliensbachian), western Europe.
Name gender	feminine
Type	Cidaris moraldina Cotteau, 1849, p. 33, by original designation [species based on indeterminate material]. Neotype designated by Vadet (1991): Museum National d'Histoire Naturelle, Paris L4.13.
Species Included	Vadet (1991) included two species when erecting this taxon: P. moraldina (Cotteau, 1849); Pliensbachian, Europe P. lorioli (Lambert, in Lambert & Thiery, 1909); Hettangian, France.
Classification and/or Status	Cidaroida; stem group (miocidarids). Strictly indeterminate; probable subjective junior synonym of Dicyclocidaris Fell, 1955 and/or Procidaris Pomel, 1883.
Remarks	The lack of complete specimens hinders diagnosis of this taxon. In interambulacral plate morphology it appears to be very similar to Dicyclocidaris and Procidaris. Vadet, A. 1991.
