Resumo: | Two new species of Polycystididae are described: &lt;i&gt;Duplacrorhynchus megalophallus&lt;/i&gt; sp. nov. from the bay of Marseille (France) and &lt;i&gt;D. heyleni&lt;/i&gt; 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 &lt;i&gt;D. megalophallus&lt;/i&gt;, and in &lt;i&gt;D. heyleni&lt;/i&gt; the muscle bulb is highly asymmetric. In &lt;i&gt;D. megalophallus&lt;/i&gt; the copulatory bulb is divided by a septum, and the cirrus has small spines and a proximal umbrella-like expansion. In &lt;i&gt;D. heyleni&lt;/i&gt; 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 (&lt;i&gt;D. minor&lt;/i&gt; Schockaert &amp; Karling, 1970 and &lt;i&gt;D. major&lt;/i&gt; Schockaert &amp; Karling, 1970) are discussed. The subfamily Duplacrorhynchinae Schockaert &amp; Karlinger, 1970 may constitute a monophyletic taxon, characterised by the 3+2 configuration of the proboscis prostate vesicle. The taxon &lt;i&gt;Duplacrorhynchus&lt;/i&gt; may be the sister taxon of all these genera.
