Original description as Deflandrea rhombohedra: [Benson, 1976, p. 195]:

Diagnosis:
Cavate cyst with left antapical horn strongly developed giving a rhomboid periblast shape.
Cyst bilayered, endophragm slightly less than 1 µm, periphragm very delicate and considerably less than 0.5 µm.
Endoblast closely appressed to periblast with lateral pericoel being less than 1 µm. Endoblast protrudes into left antapical horn, position of right antapical horn frequently represented by a slight bulge or flattening on endoblast.
Atabulate.
Archeopyle intercalary (Type I/I).
Cingulum weakly developed, slightly levorotatory, slightly depressed sulcus faintly evident with concavo-convex flagellar scar just posterior to plane of cingulum.
Endophragm smooth to microreticulate, periphragm smooth, may have faint wrinkles.

Dimensions:
Holotype: Periblast length 72 µm; width 35 µm; endoblast length 49 µm; width 33 µm; apical pericoel 9 µm.
