The hyperparasitic monogenean <I>Udonella caligorum&lt;/I&gt; Johnston, 1835, was recorded from the ichthyoparasitic copepod of the genus &lt;I&gt;Caligus&lt;/I&gt; Müller, 1785, a first record from South Africa. Different developmental stages, including filamentous eggs, egg capsules, emergent non-ciliated worms and adults of <I>U. caligorum</I>, were found associated with a &lt;I&gt;Caligus&lt;/I&gt; species. Scanning electron micrographs and observations on the development of <I>U. caligorum&lt;/I&gt; are given together with different morphological features of the developmental stages.
