Synonyms
- Spiniferites bentori : (R.Ross.) Wall e Dale
- Protoperidinium digitale : Pouchet (1883)
Morphological Characteristics
Solitary, thecate, globular in shape. The cell surface is more or less reticulate. The descendent cingulum, running in a deep groove, divides the body of the cell into two roughly equal parts, the conical epitheca, often with slightly undulating margins, and the hypotheca with 2 or 3 spines short thick on the antapex, sometimes absent. The longitudinal sulcus stretches from the apex to the antapex.
