Abstract Significant numbers of the dinoflagellate cyst genus Luehndea have been recorded from the upper Pliensbachian-lower Toarcian (Lower Jurassic) of southwestern Hungary. Two new species, Luehndea cirilliae Bucefalo Palliani, Riding et Torricelli, sp. nov. and Luehndea microreticulata Bucefalo Palliani, Riding et Torricelli, sp. nov., are described. Luehndea cirilliae comprises specimens with hollow, sinuous processes, variably developed parasutural ridges, and, sometimes, may exhibit apical and antapical protuberances. Luehndea microreticulata is characterized by gonal hollow or solid processes and microreticulate autophragm. The morphological features observed in this material, such as the morphological variety of the gonal processes and of the autophragm, the presence of apical and antapical protuberances, and the variable morphology of the parasutures, necessitated the emendation of the generic diagnosis. The stratigraphical range of Luehndea is extended into the H. falciferum Zone (early Toarcian).
