There has been some confusion about the morphology of the genus, and with fresh material this has been reviewed and a revised generic diagnosis provided. The sponge is cup-shaped, “composed from branching and radiating tubes supported on a tubular stalk” and “opened to exterior and to interior” (

). One issue was the atrial cavity of the sponge. The true atrial cavity should be considered to be the branching cavity inside the “branching and radiating tubes”, while the central cavity inside the cup could have a secondary origin and be regarded as pseudoatrial. In addition, the spicules were described as atrial (gastral) in the original description by

One problem was the interpretation of the single layer of sieve-like structures found both on the inner (mostly dermal) and pseudoatrial surfaces.

If this interpretation is not followed then the branching cavity, which would be considered atrial, should be regarded as a canal. However, this would change the systematic position of the genus to the family

as such canals should be considered as schizorhyses. This is not followed here. In summary, we provide an amended generic diagnosis due to the new specimen allowing both a revision of the interpretation of the body shape, and to update details on the spicule complement of the genus.
