The cirripeds sampled by the RV Marion Dufresne from the Vitória -Trindade seamounts (20°S, Brazil) and from depths down to 3442 meters include thirteen species: nine lepadomorphs, two verrucomorphs and two balanomorphs. Among these are two new species: Scillaelepas rhabdota n. sp. and Scillaelepas brasiliensis n. sp. S. rhabdota n. sp. has the capitular plates with strong, radial striae, the tergum has a straight apex and the rostrum is evenly curving. Scillaelepas brasiliensis n. sp. has the capitular plates with fine, radial striae and with a medial ridge, the tergum has the scutal surface smaller than carinal. Six species are new records from the southwestern Atlantic: Poecilasma aurantia Darwin, 1852, Glyptelasma carinatum (Hoek, 1883), Neoscalpellum debile (Aurivillius, 1898), Trianguloscalpellum regium (Wyville Thomson, 1873), Amigdoscalpellum aurivilli (Pilsbry, 1907), and Metaverruca recta (Aurivillius, 1898).
