Scyphosphaera apsteinii HOL

Classification: ntax_cenozoic -> Holococcoliths -> septate -> Scyphosphaera apsteinii HOL
Sister taxa: C. leptoporus subsp. quadriperforatus HOL, S. apsteinii HOL, P. japonica HOL, S. sp. type A, S. sp. type B, S. bicorium


Citation: Scyphosphaera apsteinii Lohmann, 1902 HOL
Rank: species

Distinguishing features:
Parent taxon (septate): Holococcoliths with tube, open distally and subdivided internally by vertical septae
This taxon: Liths similar to quadriperforatus but larger (3-4 µm), with more pores (8-20) and lacking castellations; single irregular boss near centre of lith.

Farinacci & Howe catalog pages: S. schilleri * , D. macroporus *


LM observations show that the ultrastructure is similar to that of Calcidiscus leptoporus ssp. quadriperforatus HOL. In comparison to quadriperforatus holococoliths the liths are larger (3-4 µm), have more pores (8-20) and a better-developed double wall - outer layer with radial c-axes, inner layer formed by extension of septae so with vertical c-axes.

Liths 3-4 µm long.

Biology & life-cycles

A single, unambiguous, combination coccosphere with Scyphosphaera apsteinii was described and illustrated by Frada et al. (2009) from the North Atlantic.
