Two new species of cumaceans are described from the deep South Atlantic off the coast of Brazil, Gaussicuma dufresnae n. sp. and Campylaspides abyssotrucidatus n. sp. Both species are in genera that typically occur in the deep sea. G. dufresnae is unique in having the following combination of features: maxilliped 3 basis not distally produced, uropod peduncle as long as rami, uropod rami subequal in length. In addition, of all the deep-sea species in this genus, G. dufresnae exhibits the least extension of the telsonic somite. Campylaspides abyssotrucidatus n. sp. differs from Campylaspides grandis Fage, 1929 and Campylaspides spinifera Jones, 1973 in having a smooth carapace and having additional large spines on maxilliped 3.
