The composition of this family has altered considerably. Originally Lambert (1896, p. 324) included a large number of genera on the basis of their apetaloid ambulacra. As Mortensen (1950) pointed out this was a hotch-potch of unrelated genera, some holasteroid, others spatangoid.
Mortensen (1950) included just two genera in the Aeropsidae, Aceste and Aeropsis. The two forms are very different in test architecture and Aceste is here considered to be an apetaloid derivative of Proraster and thus not closely related. The fossil Sphenaster represents the sister taxon to Aeropsis and links Aeropsis back to Coraster and its relatives. Corasterinae Lambert & Thiery, 1924, p. 428, is therefore here treated as the paraphyletic stem group to the Aeropsidae.
