Archeopyle type in the dinoflagellate cyst genus Imbatodinium; some new observations

A taxonomic analysis of Imbatodinium with reference to morphologically similar genera has been made. It has been determined that the mechanism of excystment is more complex than supposed hitherto, as a compound archeopyle is developed by the loss of three or four opercular pieces. A revised diagnosi...

description A taxonomic analysis of Imbatodinium with reference to morphologically similar genera has been made. It has been determined that the mechanism of excystment is more complex than supposed hitherto, as a compound archeopyle is developed by the loss of three or four opercular pieces. A revised diagnosis for the genus incorporates this new information. One new species, Imbatodinium fractum, is described and two new combinations, I. pomum (Davey) and I. radiculatum (Davey), are proposed.
