| The taxonomy of the genus <i>Polycystis</i> Koelliker, 1845 <i>sensu</i> Schockaert & Karling, 1975 is discussed. Character analysis reveals the monophyletic state of the three species groups these authors defined within it. As no synapomorphies for the three groups can be found, the genus is split in three genera: <i>Polycystis</i> Koelliker, 1845, <i>Macrorhynchus</i> Graff, 1882 and <i>Paulodora Marcus</i>, 1948. The systematic position of <i>Macrorhynchus yaganus</i> (Marcus, 1954) Evdonin, 1977 is also discussed, resulting in the erection of the new genus <i>Marcusia</i> gen. n. |

| Two new species of Polycystididae are described: <i>Duplacrorhynchus megalophallus</i> sp. nov. from the bay of Marseille (France) and <i>D. heyleni</i> sp. nov. from Zanzibar (Tanzania). The female system of both is characterized by the presence of a muscular bulb at the proximal end of the bursal stalk, with three strong teeth in <i>D. megalophallus</i>, and in <i>D. heyleni</i> the muscle bulb is highly asymmetric. In <i>D. megalophallus</i> the copulatory bulb is divided by a septum, and the cirrus has small spines and a proximal umbrella-like expansion. In <i>D. heyleni</i> only the cirrus, which has strong teeth, is enclosed in the cirrus sack: the seminal and prostate vesicles... |
