Taxonomy:

Citation: Syracosphaera histrica Kamptner, 1941 HOL
Rank: Species
Synonyms:
Taxonomic discussion: This holococcolith was only definitively established as a life cycle phase of Syracosphaera histrica by Triantaphyllou et al. (2014) so it is predominantly recorded in the literature as Calyptrolithophora papillifera

Distinguishing features: BCs tube about 9 crystallites high, no flange; distal surface flat; hexagonal mesh fabric to tube and distal cover.
CFCs vaulted with flat hexagonal mesh plates sloping towards centre from each end. Between these plates an irregular area of parallel strings of crystallites occurs.

Farinacci & Howe catalog pages: C. papillifera *


Size: Liths ca. 2 µm long.


Biology & life-cycles: A possible combination coccosphere with Syracosphaera histrica was shown by Cros et al. (2000) and further possible specimens were observed on the Patagonian Shelf by A. Poulton (Southampton, pers. comm) and by Triantaphyllou et al. (2014) from the Aegean Sea. Finally Triantaphyllou et al. (2016) documented multiple additional combination coccospheres. The combination can now be considered as established, as noted by Cros et al. (2000) the epithet histrica has priority over papillifera and so Syracosphaera histrica is the appropriate name for the species.
