Biomphalaria occidentalis Paraense, 1981 in the State of Minas Gerais, Brazil.
A population of Biomphalaria occidentalis was found for the first time in the State of Minas Gerais. It was probably introduced into the Várzea das Flores dam, in the municipality of Contagem, the area of study, during fish stocking in 1985. There is the possibility of "competitive exclusion" between that species and B. glabrata, previously the only Biomphalaria found in the region. The present geographical distribution of B. occidentalis in Brazil is listed.
