摘　　要：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.
