Classification: ntax_cenozoic -> 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.

Taxonomy:

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: S. hemirana * , S. oremesa * , S. tora *


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