A total of six genera and 10 species of marine gastropods belonging to the family Epitoniidae were collected from dredges of the continental slope off Brazil during the development of the REVIZEE (Live Resources of the Economic Exclusive Zone) Program. These species, referable to the generaAlora, Amaea, Cycloscala, Epitonium, Gregorioiscala,andOpalia,are reported from bathyal depths off northeastern Brazil.Alorasp.,Gregorioiscala pimentain. sp., andOpalia revizeen. sp. are species heretofore unknown to science. A list of the species ofEpitoniumandOpaliafrom the Atlantic coast of South America is presented based primarily on data from the literature. In addition, an overview of the biodiversity and distribution of the genera studied is presented for the Atlantic Ocean.

Abstract In this paper, we report some morphological abnormalities for the deep-sea shrimp Glyphocrangon aculeata A. Milne-Edwards, 1881, collected from the western South Atlantic. All specimens analysed herein were collected in Potiguar Basin, located in northeastern Brazil, through bottom trawls along the continental slope between 150 and 2068 m depth in 2009 and 2011. Out of 59 specimens, one ovigerous female, collected at 1074 m depth, was registered with abnormalities in some regions of the carapace, abdomen and telson. Factors such as genetic mutations, nutritional alterations, or deformities during ecdysis are suggested as being the most probable cause of the deformities reported here.

A New Species

Five species of Caprellidea (Amphipoda) occur on a benthic transect between Gay Head, Massachusetts and Bermuda. Three species, Caprella rinki Stephensen, Mayerella limicola Huntsman, and Proaeginina norvegica (Stephensen) are refigured and redescribed. A new species of Thorina and a new genus and species are described from bathyal and abyssal depths. All five species are arctic–boreal in affinities and may be expected to range south only to Cape Hatteras on the continental slope, but much farther south at abyssal depths.

Current Information

This report compiles the current information on morphology, genetics, stable isotopes, acoustics and parasites of bottlenose dolphins along the Southwest Atlantic Ocean (SWAO), which includes waters of Brazil, Uruguay and Argentina. The authors also briefly review the proposed taxonomy for the genus along the Atlantic coast of South America.

A New Species

Sediment samples were collected from the deep sea adjacent to the State of Sergipe (Northeastern Brazil) within the framework of the Sergipe Continental Slope Environmental Characterization Project (coordinated by PETROBRAS, the Brazilian Petroleum Company S/A). These revealed a new species of the family Paramesochridae (Copepoda, Harpacticoida). Kliopsyllus minor sp. nov. is the smallest species discovered in this genus, with a body length of 0.19 mm in the adult male. Furthermore, it is one of the three Kliopsyllus species registered from the deep sea so far. In almost all Kliopsyllus species, the endopod of P4 is one-segmented. Only three species, i.e. Kliopsyllus andeep Veit-Köhler, 2004 from the abyssal Weddell Sea, a new species by Veit-Köhler and Thistle from the San Diego Trough (deep Pacific Ocean) and the new species presented here, show a two-segmented endopod in the P4. Kliopsyllus andeep is distinguished by the presence of strong, chitinous processes at the telson, and additional setae at the endopods of P3 and P4. The new Pacific species and the new species from Brazil can be distinguished by the shape of the segments of the swimming legs and detailed characteristics of their setae and spines.

Both male and female of two new species, i.e. Araphura arvedlundi n. sp. and Tanaella kroyeri n. sp. were collected from the continental slope of the Atlantic coast off northern Brazil and are described. This is the first record of the male of Araphura. An updated key is given to genus Araphura. Araphura io is transferred to the genus Araphuroides.
