Diagnosis Apical disc dicyclic, plates naked except for one or two minute granules. Ambulacral plating trigeminate at ambitus and below, more irregular adapically; plate-compounding diadematid in style; pore-pairs uniserial adapically, and in arcs of three adorally. Ambulacral and interambulacral tubercles similar in size at ambitus; those in ambulacral zones sharply reduced in size above. Interambulacra with single primary tubercle plus scattered granules; a naked interradial band is present adapically. Primary tubercles on upper surface unperforated and weakly crenulated; ambital and oral primary tubercles often retaining a rudimentary perforation. [details]
