An account is presented of the restudy of seven forms of small dinoflagellate cysts from Upper Cretaceous flints of Belgium. The new genus Rhiptocorys is erected for forms having a hypotract much larger than the epitract, showing an unequal development of high crests and having an epitractal archaeopyle; the diagnosis for its type species, Rhiptocorys veligera (Deflandre), is emended. The new combination Druggidium fourmarierii (Lejeun-Carpentier) is proposed and a former variety elevated to specific status, as Druggidium leave (Lejeune-Carpentier). Emended diagnoses are proposed for both these taxa and for Dinogymnium avellana (Lejeune-Carpentier). Forms attributed by Lejeune-Carpentier (1951) to Phanerodinium cayeuxi Deflandre are reconsidered and one is redescribed as ?Phanerodinium sp. Photographs of all these forms are presented for the first time and interpretative drawings, many redrawn from the first author's original figures, supplement the text.
