Taxonomy:

Citation: Syracosphaera anthos (Lohmann 1912) Janin, 1987
Rank: Species
Basionym: Deutschlandia anthos Lohmann 1912
Variants:

Distinguishing features: see group diagnosis (monospecific)

Farinacci & Howe catalog pages: D. anthos * , D. gaarderae *


Morphology:
XCs - circular with very broad rim, elements large with kinked sutures. Central structure is small cone often with slits in base. Complete exotheca are often developed, with coccoliths showing imbricated arrangement.
BCs - long elliptical; central area vaulted, laths bipartite with step-like join forming a ring between plaque and rim; axial structure is broad plaque.
CFCs - with prominent spine ca. 1 µm high, often hidden by XCs.

Size: Coccospheres 10-15 µm; BCs 2-2.5 µm; XCs 3-5.5 µm.

Cultures: strains of this species are maintained in culture, for details see Roscoff culture collection.


Ecology & Biogeography: Mid photic

Biology & life-cycles: HOL = Periphyllophora mirabilis, see Cros et al (2000).

Coccosphere size is listed as 10-15 µm but should be 7-13µm (as listed under 'Metrics'/ Cros & Fortuño 2003).

Good point - I have corrected that now, after also checking the imaged specimens.
