Like Diademposis in having prominent secondary tubercles but distinguished in having pore-pairs arranged in a broad zone rather than a single series and in having ambulacral and interambulacral tubercles of similar size. Very like Pedina in ambulacral plating and pore-pair arrangement but differing from that genus in having denser and more prominent tuberculation. It also has a primary ambulacral tubercle developed on each compound ambulacral plate.
