Citation: Syracosphaera leptolepis Kleijne & Cros 2009
Rank: Species

Distinguishing features: XCs circular, small (1.5-2µm)

Farinacci & Howe catalog pages: S. leptolepis *

Morphology: Coccosphere spherical (6-9 µm).
BCs - broadly -elliptical (1.7-2.5 µm), with thin, low, wall; central-area, broad, slightly vaulted, with low axial mound formed of lath tips and disjunct plates.
XCs - circular (1.6-2.0 µm), very thin, with central cycle of dextrally oblique radial elements and rim of wide elements. (XC structure is similar to that of S. nana)
