Mesoporus perforatus, from the Alfred Wegener Institute.

Belongs within: Peridinoidia.
Contains: Dinophysiales, Prorocentrum.

The Dinophysiphycidae was defined by Fensome et al. (1993) to include dinoflagellates that possess a sagittal suture together with a cingulum and a sulcus. However, the same publication also suggested that this group was paraphyletic with regard to the Prorocentraceae, which have lost the cingulum and sulcus.
