Taxonomic rank: species
Basionym: Rhabdolithus splendens * Deflandre 1953

Synonyms:

Distinguishing features:
Parent taxon (Rhagodiscus): Loxolith coccoliths with low rim and central-area filled by a granular plate which may be perforate and/or spine-bearing. In xpl the rim is unicyclic moderately bright, the central area is granular, lacking a clear extinction cross.
This taxon: Large Rhagodiscus coccoliths with a very broad spine-base that is distinctly striated in LM XPL.

Search data:
LITHS: murolith, elliptical, CA: plate, process, CROSS-POLARS: rim-unicyclic, R-prominent,
Lith size: 8->12µm;
Data source notes: illustrated specimens
