Scyphosphaera hemirana

Classification: Coccolithophores -> Zygodiscales -> Pontosphaeraceae -> Scyphosphaera -> Scyphosphaera hemirana
Sister taxa: S. apsteinii, S. porosa, S. brevis, S. globulata, S. hamptonii, S. hemirana, S. lagena, S. campanula, S. intermedia, S. pulcherrima, S. tubifera, S. ventriosa, S. columella, S. expansa, S. interstincta, S. olla, S. tercisensis, S. tubicena, S. sp.,


Citation: Scyphosphaera hemirana Kamptner 1967
Rank: Species
Synonyms: 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: Cylindrical Scyphosphaera with fluted sides

Farinacci & Howe catalog pages: Scyphosphaera hemirana * , Scyphosphaera oremesa * , Scyphosphaera tora *

Morphology remarks: The illustrations appear distinctive but the species has never been described properly and posibly is based on debris from another calcareous microfossil
