Scyphosphaera ventriosa


Classification: Coccolithophores -> Zygodiscales -> Pontosphaeraceae -> Scyphosphaera -> Scyphosphaera ventriosa
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 ventriosa Martini, 1968
Rank: Species
Variants:
Notes & discussion: The holotype specimen of S. ventriosa is rather broader than most specimens but clearly has the weak collar which is the main criterion for grouping these forms, and the name has priority over the other variants included here.

Distinguishing features: Similar to S. apsteinii but with low collar around opening.
