A new species of the nudibranch genus Doriopsilla Bergh, 1880, D. debruini, is described from Hout Bay, South Africa. The new species is distinguished externally by a number of large dark brown patches, the presence of high rhinophore sheaths and a very deep notch on the anterior foot. Internally the arrangement of the organs is typical for the genus with the presence of a large female gland and a flat prostatic gland. Differences between the known species are tabulated.
