- Abstract:
  Three species of dinophysoid planktonic dinoflagellates are described from the eastern Mediterranean Sea. Amphisolenia sp. aff. brevicauda was collected at 70-m depth in the Ionian Sea. This small species showed a more asymmetric midbody and a proportionally longer neck when compared to the closer relative A. brevicauda. Three individuals of Dinofurcula tricornuta sp. nov. collected at 154-m depth in the Marmara Sea are characterized by three posterior-oriented processes when compared to its congeneric species. This is the first record of the genus Dinofurcula beyond the eastern tropical Pacific Ocean. Dinophysis profunda sp. nov. collected at 500-m depth in the Ionian Sea is characterized by ovate hypotheca and a serrate crest-like left sulcal list when compared to its close relative D. alata. These findings evidence an undescribed biodiversity in the under-sampled subphotic depths. [ABSTRACT FROM AUTHOR]
