Abstract

Six species of the fresh water snail were collected from a total of 29 sampling sites. To evaluate genetic variability within and between populations, enzymes coded for by 18 presumed loci were examined by starch gel electrophoresis.<br>Out of the six species, three (<i>S. niponica, S. multigranosa</i> and <i>S. nakasekoae</i>) were endemic to the Lake Biwa and remaining three (<i>S. libertine, S</i>. <i>reiniana</i> and <i>S. kurodai</i>) were the snail species widely distributed throughout Japan. The proportion of polymorphic loci and the expected average heterozygosity per individual for the three endemic species were 0.120±0.069 and 0.019±0.003, respectively. Those for the three widespread species were 0.179±0.068 and 0.058±0.017 (mean±S.D.), respectively. The present result showed that the <i>S. kurodai</i>, which has been considered to be transitional between the <i>S. libertine</i> and <i>S, niponica</i> complexes (Davis, 1969), should be classified into the Davis′s <i>S. libertina</i> complex.
