Resumo: | In this contribution we present eleven species of Rhabdocoela (Platyhelminthes) collected during the Antarktis VII/4 (Epos leg. 3) expedition. Six of them belong to the family Trigonostomidae (Typhloplanoida). Five of these are new to science: &lt;i&gt;Trigonostomum messoplanoides&lt;/i&gt; n. sp., Proxenetes trispinosus n. sp., &lt;i&gt;Messoplana globulifera&lt;/i&gt; n. sp., &lt;i&gt;M minuta&lt;/i&gt; n. sp. and &lt;i&gt;M. spiralis&lt;/i&gt; n. sp. AII the species can be recognised from congeneric species by the shapes of their stylets. &lt;i&gt;Ceratopera axi&lt;/i&gt; (Riedl, 1954) Den Hartog, 1964 also was found and is discussed brief1y. The other five species belong to the family Polycystididae (Eukalyptorhynchia). Three of them are new to science and belong to the genus &lt;i&gt;Austrorhynchus&lt;/i&gt; Karling, 1952 : &lt;i&gt;A. magnificoides&lt;/i&gt; n. sp., &lt;i&gt;A. antarcticus&lt;/i&gt; n. sp. and &lt;i&gt;A. biserratus&lt;/i&gt; n. sp. They differ from other &lt;i&gt;Austrorhynchus&lt;/i&gt; species in having a triangular shape of the accessory organ of the male system. Particular differences in shape of the stylet and accessory organ clearly distinguish each of the new species. Unlike the other two species, &lt;i&gt;A. antarcticus&lt;/i&gt; lacks a hook on the stylet. The genus &lt;i&gt;Austrorhynchus&lt;/i&gt; is brief1y ,discussed. The collected material of &lt;i&gt;Gyratrix hermaphroditus&lt;/i&gt; Ehrenberg, 1831 and &lt;i&gt;Porrocystis assimilis&lt;/i&gt; (Levinsen, 1879) Karling, 1952 is also brief1y discussed.
