Citation: Syracosphaera hastata Kleijne & Cros, 2009
Rank: Species

Distinguishing features: BCs narrow smooth rim; CFCs with tall spines

Farinacci & Howe catalog pages: S. hastata *

BCs - flanges smooth and narrow; no distinct axial structure.
CFCs - distal flange very narrow; tall (ca. 2 µm) spines with calyx of four triangular plates.
AACs - one or two usually present, similar to CFCs but rim higher and calyx larger.
XCs - with broad smooth flange extended into wings; central part conical

Size: Coccospheres 6-10 µm; BCs 1.3-2.2 µm; XCs 2.3-3.1 µm.
