FIGURE 1. General characteristics of the parthenitae and cercariae of the trematodes infecting Potamopyrgus antipodarum as first intermediate host. Microphallus sp. "livelyi" (sp. 13), whose embryos develop directly to metacercariae, is not figured. Species numbers and codes follow Table 1 and species accounts. Cercariae are all to scale, with additional magnified views of three small cercariae (indicated by dashed lines). Parthenitae are not to scale. Scale bars consistently indicate 100 µm.
