Both these species weredescribed from the same material as S. hemirana and the holotypes appear very similar. S. hemirana has page pririoty and is based on the clearest holotype. [JRY 2016]
Distinguishing features: Parent taxon (Scyphosphaera): Coccospheres with Pontosphaera-like body coccoliths and equatorial coccoliths with rims elevated into vase-like structures (lopadoliths). This taxon: Cylindrical Scyphosphaera with fluted sides
Geological Range: Notes: The type material is a dredged holocene ooze (Challenger station 338), but it inlcudes reowrked specimens Last occurrence (top): within Late Pleistocene Sub-Epoch (0.01-0.13Ma, top in Tarantian stage). Data source: Kamptner 1967 First occurrence (base): within Pleistocene Epoch (0.01-2.59Ma, base in Gelasian stage). Data source: Kamptner 1967
