Distinguishing features:
Parent taxon (laminated type): XCs consist partly or entirely of several layers of superposed elements. CFCs with spines
This taxon: XCs with openings around part of coccolith


Morphology:
XCs - asymetrical planoliths (ca. 2.5 µm). laminated wing extends around half width, other half of lith with narrow rim and openings between radial elements.
BCs - elliptical; rim broad with clear inner cycle; central area with well separated radial laths, weak central body (1.4-1.7 µm).
CFCs -similar to BCs but with short, pointed, spine

Size:
Coccospheres 6 µm.
