If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|Y. Wang et al. 2003||Two or more, well developed, spherical or subspherical shells, and an internal, six-rayed double spicule. When secondary spines are present, the six spines developed from the rays of the internal spicule are generally differentiated and recognizable as main spines. Up to six main spines may be present.|
