Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Cyphonium hexagonium under the subgeneric name Ommatocyrtis, but did not include the subgeneric name in the species name.
Haeckel, 1887a, p.364 referes this species to Didymocyrtis hexagonia in Haeckel, 1881a, but no species were recorded in that publication.
