Resumo: |
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 are not. Relationships with the two known species of the genus (<i>D. minor</i> Schockaert & Karling, 1970 and <i>D. major</i> Schockaert & Karling, 1970) are discussed. The subfamily Duplacrorhynchinae Schockaert & Karlinger, 1970 may constitute a monophyletic taxon, characterised by the 3+2 configuration of the proboscis prostate vesicle. The taxon <i>Duplacrorhynchus</i> may be the sister taxon of all these genera.
