Both Mortensen (1928) and Fell (1966) chose to ignore this taxon. However, Pomel's original designation was sound, although he did not designate a single type species, and the genus is valid. The strongly congugate pore-pairs and dense aligned interradial granulation distinguish this genus.
The non-crenulate nature of the primary tubercles and the dense homogeneous extrascrobicular granulation distinguish this taxon from Rhabdocidaris and its relatives. However, there are no significant differences in test morphology that distinguish it from Prionocidaris.
