The assay has shown that the most closely related are three species of <i>Echinoparyphium</I> while <i>P. echinatum</i> and <i>N. echinatoides</i> were more distant, especially the latter. <i>H. conoideum</i> appeared to be close to <i>Echinoparyphium</i>. The analysis of sequences of ITS1 region of rDNA and RAPD profiles corroborated with earlier conclusions based on chaetotaxy of cercariae and the excretory system patterns. <hr> KEY WORDS: <i>Echinoparyphium</i> spp., phylogeny, ITS1, rDNA <hr> <h6> <center> <font color="aqua">Page compiled by Aleksander H.Kedra.
