This cidaroid resembles Lenticidaris in its interambulacral structure and tuberculation, but is immediately distinguished from this, and indeed from most other cidaroids, by its unique pseudocompound ambulacra and broad pore zones. Only Heterocidaris and Serpianotiaris have comparable ambulacra, and they both have different tuberculation and perignathic girdle. The taxon was described in admirable detail by Hagdorn (1995).
