Although previously placed in the Phymosomatidae, the ambulacral plate compounding style and the compact hemicyclic apical disc with smooth periproctal outline immediately distinguish this from all other members of that family. Its ambulacral plate compounding is similar in style to that of Stomopneustidae, but those all have non-crenulate tubercles. Jensen (1982) erected the family Glyptocidaridae to accommodate this genus.
