[Plankton • 2018] Syracosphaera azureaplaneta sp. nov. and Revision of Syracosphaera corolla Lecal, 1966

Syracosphaera azureaplaneta
 Young, Bown, Cros, Hagino & Jordan, 2018

Here we show that the extant coccolithophore Syracosphaera corolla Lecal, 1966 comprises two consistently different non-intergrading morphotypes characterised respectively by exothecal coccoliths with wide and narrow central-areas. These are interpreted as separate species and so a new species is described, Syracosphaera azureaplaneta, and a revised description is given for S. corolla.

Keywords Coccolithophores, Syracosphaera, extent

Syracosphaera azureaplaneta sp. nov.
