title: [The distribution of Biomphalaria (Gastropoda, Planorbidae) in the states of Rio Grande do Sul and Santa Catarina, Brazil].
abstract: An analysis to determine new localities colonized by the intermediate snail hosts (B. straminea, B. tenagophila and B. tenagophila tenagophila) of Schistosoma mansoni from Rio Grande do Sul and Santa Catarina States (Brazil) was carried out. As regards the geographical distribution of the schistosomiasis vector, the possible extension of the endemic disease to Southernmost Brazil is commented on.
