Validation here of the name Bysmatrum arenicola Horiguchi et Pienaar sp. nov. rather than Scrippsiella arenicola for this sand-dwelling dinoflagellate from South Africa also corrects the inadvertently invalid basionym publication.

Bysmatrum subsalsum is a cosmopolitan dinoflagellate species that inhabits marine and transitional habitats. Despite its wide distribution, information on the morphological variability, phylogeny and ecology of B. subsalsum is scarce. In this study, we

The type material of Peridinium gregarium Lombard et Capon, originally described from tidal pools in Southern California has been re-examined. Two of the three slides that have been deposited in the Herbarium, California State University, contained two

Biomonitoring of dinoflagellate communities in marine ecosystems is essential for efficient water quality management and limiting ecosystem disturbances. Current identification and monitoring of toxic dinoflagellates, which cause harmful algal blooms,

ABSTRACTA new dinoflagellate, Scrippsiella arenicola Horiguchi et Pienaar sp. nov., is described from tidal pools with sandy substrates along the east coast of South Africa. S. arenicola exhibits a vertical migratory rhythm which is in synchrony with
