Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly complied on this site. The "Catalogue of Calcareous Nannofossils" was compiled by Prof A. Farinacci 1969-1989 and updated by Richard Howe 2000-2016 - see also this page.

Citation: Lebessphaera Meier et al. 2002
Rank: Genus
Type species: Lebessphaera urania Meier, Janofske and Willems 2002


Original Description
Calciodinelloid dinoflagellate cysts built by a single calcareous layer. Crystals of the calcareous cyst wall layer are oriented with their crystallographic c-axis tangential to the cyst surface. Paratabulation patterns are present. The operculum includes apical, intercalary, and precingular plates. Epicystal archeopyle.

Etymology: Latin: lebes

Extra details from original publication
Discussion. A calcareous dinoflagellate genus with an epicystal archaeopyle has not yet been described. Large archaeopyles are present in species of the genera Scrippsiella and Pernambugia as well (Janofske 2000, Janofske and Karwath 2000), but a paratabulation given by the reflection of precingular plates in the operculum is not present. Therefore we suggest the new genus Lebessphaera that contains all cysts with tangential wall structure and an epicystal archaeopyle. A cyst–theca relationship is not given here, because cysts of this new genus could not be germinated successfully in cultures.
