摘要: Abstract: A new species, Pentapharsodinium jinhaense sp. nov., was established by incubating resting cysts, which were collected from trap samples Jinhae-Masan Bay, Korea. The cysts of P. spherical or ovoidal, with a large reddish pigment body and thick wall covered numerous needle-shaped calcareous crystals. size, shape plate tabulation motile cells that germinated the similar to those Pentapharsodinium tyrrhenicum Ensiculifera carinata; however, had spine located in anterior sulcal many pores spines on thecal surface. Molecular phylogenetic analysis using internal transcribed spacer 5.8s rDNA showed closely related tyrrhenicum. Large subunit ribosomal DNA sequences also revealed nested within formed strongly supported clade dalei
