New collections made by the French research vessel Thalassa and the Brazilian Astro Garoupa on the Brazilian continental slope, between 11° and 23° S revealed a great diversity of deep-sea gadiforms obtained between 200 and 2270 m. Of the 34 species collected, 13 (38%) are being reported for the first time in the western South Atlantic and one may represent a new species. The most species-rich family in the area is Macrouridae (25 species), followed by Moridae (4), Phycidae (2), Merlucciidae (2), and Bregmacerotidae (1). Most of the species collected is also found in the Gulf of Mexico and Caribbean and have their known ranges of distribution extended into the tropical waters of central Brazil. Four species typically occur in temperate waters and were found only in the southernmost stations. A summary comparison of the bathymetric distributions of each species on the slope is provided.
