AB A new species of the genus Fragilidium, F. duplocampanaeforme sp. nov., is described from examinations by LM and SEM. This species has been recorded in summer on the French Atlantic coast, over a number of years. It was never abundant in the plankton and was very often associated with Fragilidium subglobosum, Pyrophacus horologium and also with toxigenic species of the genera Alexandrium and Dinophysis. Phagotrophy of F. duplocampanaeforme on Dinophysis prey is shown, and sexual reproduction is suggested by the observation of gamete-like small forms. The size and the peculiar shape of its cells do not correspond to any known taxon, but the plate arrangement fits the genus Fragilidium. The plate formula is Po, Pc, 4', 8 '', 10c, 6s?, 7"', 2 '''', lp. A close examination of the plate morphology reveals an apical closing platelet Pc and significant differences from known Fragilidium species. Plate ornamentation is complex. A longitudinal fold and an unusual optional pore are seen on the antapical plate 2 ''''. Other distinctive morphological features are emphasized which discriminate this new species from others of the genus Fragilidium.
