Differs from Pseudopedina only in having a primary tubercle to each ambulacral compound plate and in having pore-pairs uniserially arranged from the ambitus adapically. Differs from Hemipedina in being much more globular and with adapical primary tubercles more adradial in position. It is also rather more sparsely tuberculate adapically. Close to Diademopsis, but differing in having taller ambital and adapical interambulacral plates on which the primary tubercles are distinctly separated.
