Taxonomy:

Citation: Jomonlithus Inouye & Chihara, 1983

Rank: Genus

Type species: Jomonlithus littoralis Inouye & Chihara, 1983

Distinguishing features: Murolith coccoliths with simple rim, partially calcified specimens show beaded ultrastructure.

Farinacci & Howe catalog pages: Jomonlithus [no catalog entry yet]

Phylogenetic relations: The genus Jomonlithus was described from a similar coastal environment to the Pleurochrysidaceae and Hymenomonadaceae and it is similar in basic morphology although the coccolith structure seems different. Its placement in the Hymonomonadaceae is based on molecular genetics data (Sa_ez et al., 2004).
