The new genus Dionella is proposed for membranimorph Polyzoa from the Upper Cretaceous of Europe having slightly calcified frontal walls, dietellae, hyperstomial ovicells, and small interzooecial avicularia, which, when present, are distal to the ovicells. The type material of the seven species assigned to this genus is redescribed with the establishment of lectotypes, a neotype, and many synonymies. A possible evolutionary pattern for the group has also been given.
