Allison et al. 1967 placed this taxon in the Asterostomatidae due to its lack of fascioles. However, the plastron structure, with ambulacral plate 5 at the rear of the sternal plates and the paired episternal plates that abut at their rear amb plate 6, indicates relationships with Micrasterina. It is very similiar to Palaeobrissus, differing primarily in its more inflated shape and in having ambulacra uniserial adapically.
