Jomonlithus littoralis


Classification: ntax_cenozoic -> Coccolithales -> Hymenomonadaceae -> Jomonlithus -> Jomonlithus littoralis
Sister taxa: J. littoralis, J. sp.

Taxonomy:

Citation: Jomonlithus littoralis Inouye & Chihara, 1983
Rank: Species

Distinguishing features: See generic diagnosis

Farinacci & Howe catalog pages: J. littoralis [no catalog entry yet]


Size: Coccoliths 1-1.5 µm. Coccospheres 10-12 µm

Cultures: strains of this species are maintained in culture, for details see Roscoff culture collection.


Biology & life-cycles: A motile non-calcifying haploid phase alternates with the non-motile coccolith bearing diploid phase occurs (Probert eal. 2014) 

Phylogenetic relations: Previously tentative placement close to the Hymenomonadaceae was confirmed by molecular genetics by Probert et al. (2014) who also emended the definition of the family to include Jomonlithus.
