title: Brachyrhynchus n. gen. n. sp., a new genus of Polycystididae Graff, 1905 (Rhabdocoela: Kalyptorhynchia), with the description of three new species from the Mediterranean and the Indian Ocean.
abstract: Three new species of Polycystididae are described: Brachyrhynchus triplostylis n. gen. n. sp., B. acutus n. sp. and B. oosterlyncki n. sp. They are the first species of Polycystididae to be described with a second, single-walled accessory stylet connected to a small glandular vesicle in the male system. The three species can be distinguished from each other by the detailed morphology and the relative lengths of the three stylets in the male system. The relationships of these species with other representatives of Polycystididae are discussed.
