Anthosphaera lafourcadii

Classification: Coccolithophores -> Holococcoliths -> tubeless -> Anthosphaera -> Anthosphaera lafourcadii
Sister taxa: S. marginiporata HOL, S. molischii HOL, A. lafourcadii, A. origami, A. periperforata, A. sp. type C, A. sp.,


Citation: Anthosphaera lafourcadii (Lecal 1967) Kleijne, 1991
Rank: Species
Basionym: Helladosphaera lafourcadii Lecal 1967
Notes & discussion: Lecal (1967) refered to this species variously as Helladosphaera lafourcadiiHelladosphaera (Cyclohelladosphaera) lafourcadii and Cyclohelladosphaera lafourcadii

Distinguishing features: Like S. molischii HOL but BCs small, with irregular crystallites

Farinacci & Howe catalog pages: Helladosphaera lafourcadii *

Morphology remarks: Like A. fragaria, but BCs smaller (ca. 1 µm), and with less regular crystallites, ring of pores more consistently present, rim narrower; CFCs with low process (<1 µm).
