Acanthoica laffittei

Classification: Coccolithophores -> Syracosphaerales -> Rhabdosphaeraceae -> Acanthoica -> Acanthoica laffittei
Sister taxa: A. quattrospina, A. acanthifera, A. acanthos, A. biscayensis, A. janchenii, A. maxima, A. sp A, A. backmanii, A. cohenii, A. laffittei, A. sp.,


Citation: Acanthoica laffittei (Jerkovic 1971) Aubry 1999
Rank: Species
Basionym: Blackites laffittei Jerkovic 1971

Distinguishing features: Circular to broadly elliptical; rim broad; two concentric lath cycles; low central protrusion

Farinacci & Howe catalog pages: Blackites laffittei * , Blackites balcanicus * , Syracosphaera beogradiensis *

Morphology remarks: The concentric lath cycles are best seen on the proximal surface, on the distal surface they are often obscured by irregular laths extending down from the central protrusion. Coccolith shape varies from circular to distinctly elliptical, even on single collapsed coccospheres.
