Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. R. C. Paul et al. 2019 | As for the superfamily: Directly attached diploporites with elongate oral area surrounded by at least eight plates (four inter-radial peri-orals [POO] and four radial circumorals [COO]), and covered by a double biseries of cover plates; with two to five ambulacra bearing one to four brachioles each; with a large hydropore shared by plates PO1 and PO6, and often a spout-like gonopore usually within a single plate near the periproct; with thecal plates densely covered with diplopores that are commonly sealed externally by a thin epistereom and sometimes extended into spine-like projections. |
