Abstract

Parasitological examination of specimens of Heleobia parchappii (d’Orbigny, 1835) and Heleobia australis (d’Orbigny, 1835) (Mollusca, Cochliopidae), from freshwater and estuarine environments of the Buenos Aires province (Argentina), revealed the presence of 7 new larval stages of digeneans (cercariae) for these molluscan hosts. These larval stages of digeneans include two xiphidiocercariae, and 5 cercariae belonging to the families Acanthostomidae, Schistosomatidae, Aporocotylidae and Haploporidae, respectively.
