Lambert, in erecting this species, allied it with corasterids. He recognized a marginal fasciole, but presumably poor preservation has obliterated the posterior part of the peripetalous fasciole. The type material needs restudy.
Chesher (1968) described a new living species that he assigned to this species. It is very similar to Prenaster, differing only in having subpetaloid rather than petaloid ambulacra.
