Abstract:
Round spiny brown cysts with apiculocavate processes were isolated from sediments of L ake S aroma, J apan, C hangle H arbor, E ast C hina S ea, C hina, J inzhou H arbor, B ohai S ea, C hina, and S an P edro H arbor, C alifornia, USA . Superficially similar round spiny brown cysts of the species, O blea acanthocysta were, for comparison, restudied through light microscopy and scanning electron microscopy ( SEM ) and by sequencing of small subunit ( SSU) and large subunit ( LSU) rDNA obtained through a single cyst from L ake S aroma. These morphological measurements and SEM observations showed that the new cysts can be discriminated from O . acanthocysta by the archeopyle, number of processes, shape of process bases and its apiculocavate processes . Based on LSU sequences, the most closely related species was P rotoperidinium monovelum , for which no cyst stage has been described so far. However, the thecal morphology of the specimens found in this study differed from P . monovelum in details of the sulcal plates and shape of apical pore and 2a plate. We therefore describe P rotoperidinium lewisiae sp. nov., which can be found in estuarine subtropical to temperate waters of the P acific O cean.
