Species Syracosphaera elevata Archontikis, Young, Cros sp. nov. HOL
Synonymy: Holococcolithophore sp. 2 ( Anthosphaera View in CoL affinity?) Cros (2001), p. 97, Pl. 75, Figs. 3–4 View Plate 3 .
Anthosphaera sp. type C Cros and Fortuño (2002), p. 60, Figs. 88C, 88D; Young et al. (2003), p. 90, Pl. 42, Figs. 8, 11.
Derivatio nominis: From Latin elevatus –a –um (adjective), elevated; referring to the elevated arch of CFCs.
Description: Coccosphere, most probably spheri- cal in shape but usually seen collapsed/flattened, with c. 250 BCs and 5–12 CFCs. BCs are characteristically minute (<1 µm) and partially calcified with an elliptical rim. BCs’ rim structure consists of an outer ring of tiny rhombohedral crystals that are loosely connected with an assembly of irregularly arranged, tiny crystallites in the central structure, thus leaving somewhat broad per- forations; a few BCs with only a rim sometimes occur ( Plate 6 View Plate 6 , Fig. 3 View Plate 3 ). CFCs consist of a similarly constructed rim, possessing though, a high arch (height> 2 x width) with a low triangular apical spine.
Remarks: The BCs are similar to those of S. marginiporata , although without the perforate microstructure. The CFCs with the very high arch are unique and quite different to those of S. marginiporata .
Dimensions: Coccosphere diameter c. 6 μm. BCs 0.4–0.8 μm long x c. 0.4 μm wide. CFCs c. 0.5 μm long x 0.5–0.8 μm wide; distal process is 1.2–2.0 μm high.
Holotype: Specimen illustrated in JRYSEM-177-72 ( Plate 6 View Plate 6 , Fig. 1 View Fig ), stub 302-02, curated at the NHM, Lon- don, UK.
Paratype (s): Specimens illustrated at Plate 6 View Plate 6 , Figs. 3–4 View Plate 3 .
Type locality: Station 69–11, 42.5m water depth, collected from the western Mediterranean Sea (37°43N, 0°42W), cruise MATER II, October 1999 GoogleMaps .
Number of specimens studied: 9
Distribution: Northwestern Mediterranean and Alboran Seas
