[?=Polypedina Lambert, 1933, p. 46, type species Polydiadema toutanensis Lambert, 1933; =Soudetaster Vadet, Nicolleau & Riboul, 2011, p. 6, type species Soudetaster martinezae [?=Pedina bakeri Wright 1854] ]
Jurassic (Bajocian to Oxfordian), western Europe.
Pseudopedina nodoti Cotteau, 1858, p. 223 by monotypy. Cotteau (1884, p. 662: Paleontologie francaise) later treated this species as a junior synonym of Pedina bakeri Wright, 1854. However, Vadet & Slowik (2001, p. 14) synonymize it with Echinus divionensis Michelin, 1854), which seems more likely given its large secondary interambulacral tubercles.
