Classification: ntax_cenozoic -> Holococcoliths -> flat-topped -> Helicosphaera HOL -> Helicosphaera HOL catilliferus type
Sister taxa: H. HOL catilliferus type, H. HOL confusus type, H. HOL ponticuliferus type, H. pavimentum HOL

Taxonomy:

Citation: Helicosphaera HOL catilliferus type
Rank: species
Basionym: Syracosphaera catillifera Kamptner 1937
Synonyms:
Taxonomic discussion: Nomenclature here follows Young & Bown (2014)

Distinguishing features: Liths with flat-top without perforations; pyramidal boss near centre; rim 5-6 crystallites high; central opening on proximal side small or absent;

Farinacci & Howe catalog pages: S. catillifera * , S. cornus *


Morphology: The absence of perforations results in the rhombohedral array structure being particularly clearly visible, in good SEMs

Size: Liths 2-3 µm long; 5-7 crystallites high


Biology & life-cycles: Combination coccospheres with Helicosphaera carteri observed but also observed in culture as alternate stage of H. wallichii (K. Hagino pers. comm.)
