A new species of solenogaster (Mollusca, Aplacophora) from the Angola Basin is described: Macellomenia profundorum n. sp. The studied specimen was collected during the DIVA 1 expedition (Latitudinal Gradients of Deep-Sea BioDIVersity in the Atlantic Ocean). The description is based primarily on the sclerites and the internal anatomy (histological study). Macellomenia profundorum n. sp. is the first species of the family to be described from the southern hemisphere and constitutes its deepest record (5400 m deep). Even though only anterior anatomical characters are known, these and especially the radula and mantle sclerites are enough to justify that it is a new species. Amended diagnoses are also provided for the family and genus.
