There are two families in this superfamily, which is listed as the only superfamily in the clade Umbraculida within the informal group Opisthobranchia in the taxonomy of Bouchet & Rocroi (2005).[2]

Taxonomy

edit

A study by Grande et al., published in 2004, concluded that Umbraculoidea was a sister clade to the Cephalaspidea (Acteonoidea excluded).[3]

2005 taxonomy
