A palynological study of Campanian-Danian chalks from the quarries at Beutenaken and Hallembaye (Maastricht region) and from a borehole at Turnhout (northern Belgium) has revealed the presence of seven new species and subspecies of dinoflagellate cysts: <i>Exochosphaeridium? Masureae</i> sp. nov., <i>Leberidocysta chlamydata</i> subsp. <i>schiolerii</i> subsp. nov., <i>Odontochitina streelii</i> sp. nov., <i>Pervosphaeridium septatum</i> sp. nov., <i>Spiniferites ramosus</i> subsp. <i>pterocoelus</i> subsp. nov., <i>Stephodinium? spinosum</i> sp. nov. and <i>Xenascus wetzelii</i> sp. nov. <i>Nexosispinum? complicatum</i> described by Slimani (1996) as a new species is now a junior synonym of <i>Pulchrasphaera minuscula</i> Schiøler <i>et al.</i> (1997).
