Abstract (in english)
   A new porcelliid gastropod genus, Sasakiela gen. nov., is described from the Lower Carboniferous of Belgium. It is based on Pleurotomaria ryckholtiana KONINCK, 1843, and it is placed into the subfamily Agnesiinae of the Porcelliidae (Archaeogastropoda). The first two whorls of the teleoconch of Sasakiela are openly and planispirally coiled which suggests that juveniles of S. ryckholtiana (KONINCK, 1843) lived possibly within the interstices of algal thickets or reef debris like many species of the modem Caecidae. In contrast to the juveniles the adult Sasakiela ryckholtiana had a tightly coiled trochospiral shell and lived more exposed among the organisms of the reef environment. The distribution of openly coiled shells amongst Paleozoic gastropods is briefly discussed
