variolaris is the only living species in the family Stomopneustidae, order Phymosomatoida, within the superorder Stirodonta along with arbacioid and salenioid echinoids (e.g., Smith 2005; Smith et al., 2006).
Stomopneustes variolaris has long been placed in the superorder Stirodonta because of the structure of its Aristotle's lantern: keeled teeth, small epiphyses, and an open foramen magnum over each tooth (Jackson, 1912).
