The cyst-theca relationship of the dinoflagellate cyst Trinovantedinium pallidifulvum, with erection of Protoperidinium lousianensis sp. nov. and their phylogenetic position within the Conica group
We establish the cyst-theca relationship of the dinoflagellate cyst species Trinovantedinium pallidifulvum Matsuoka 1987 based on germination experiments of specimens isolated from the Gulf of Mexico. We show that the motile stage is a new species, designated as Protoperidinium louisianensis. We als...
