?Objective junior synonym of Hungaresia Szorenyi, 1955.


Kier (1962) reports that the specimen of the type species he has studies is in all likelihood an immature specimen of Hungaresia hungarica Szorenyi, with a similarly inflated test, petal arrangement, inframarginal periproct, and single-pored phyllodes. This is supported by the fact that all specimens studied by Szorenyi are small and come from the same locality as H. hungarica.
