From editor or global species database
Diagnosis Echinocystitid with heavily imbricate, scale-like interambulacral plates, and uniserial half-ambulacra. Ambulacral plates are about 1.5 times wider than high, and alternating plates are differentially enlarged or reduced in size. Interambulacral and ambulacral plates are covered with small pits, into which ball-like spine bases articulate. Some interambulacral plates have a large, sunken pit, which dominates the plate. [details]
