Identification and characterization ofBiomphalaria peregrina(Orbignyi, 1835) from Agua Escondida in northern Patagonia, Argentina [PDF]

Journal of Natural History, 2011
During a general malacological survey for freshwater gastropods in northern Patagonia, a population of Biomphalaria was encountered at Agua Escondida. Biomphalaria spp. are freshwater pulmonates of biomedical importance, uncommon in Mendoza Province, and often act as intermediate hosts for Schistosoma mansoni.
