Despite the increasing number of reports on the deep-sea molluscs from the south-western Atlantic, we know very little about the protobranchs. The lack of information on the protobranch Pelecypoda off southern Brazil is reflected in the genusYoldiella. This contribution is part of an effort to increase the knowledge about this group off the Brazilian coast. Eight species ofYoldiellaare recognized here. ForYoldiella biguttata, previously reported from Brazil, the known distribution is extended southwards to the Campos Basin. ForYoldiella similisthis is the first record in the western Atlantic Ocean. ForYoldiella extensaandYoldiellaaff.jeffreysithis is the first record for Brazil. Four previously unknown species are described,Yoldiella lapernoisp. nov.,Yoldiella paranapuaensissp. nov.,Yoldiella arariboiasp. nov. andYoldiella curupirasp. nov. Considering only conchological features for the Atlantic species we could propose some clusters of species ofYoldiella.

A New Species

Despite the increase in the number of deep-sea studies, little is known about the hadal molluscs. For Brazil, only a few studies have treated the Septibranchia. This contribution is part of an effort to increase the knowledge of this group off the Brazilian coast, although it is focused only on the Campos Basin (22°S), State of Rio de Janeiro. Four species of the family Verticordiidae are recognized here. ForSpinosipella tingaSimone & Cunha, 2008, the known depth distribution is extended to 1050 m. ForVerticordia woodiiSmith, 1885, previously reported from Brazil, the known distribution is extended southwards to the Campos Basin.Verticordia quadrataSmith, 1885, is reported from Brazil for the first time. A previously unknown species,Verticordia ouricurisp. nov., is described. The presence of small spines, typically with a hexagonal column and a stellate structure at their distal end emerges as an additional taxonomic character for the verticordiids.

As a part of the Environmental Characterization of the Campos Basin project, we obtained samples from the continental slope benthos. As a consequence, specimens of Tindariopsis aeolata (Dall, 1889) and Tindariopsis agathida (Dall, 1889) were found. These species show prodissoconch surface sculpture patterns that were never seen for species of Tindariopsis. The presence of this kind of sculpture in the type species of the genus, T. agathida, adds diagnostic characters to the genus. T. agathida and T. aeolata are typical from the Caribbean Realm (Guyana and Tobago). This is the first record of T. aeolata in the southernmost area of the Atlantic Ocean, and also the shallowest record (1000 m) for this species. With this finding of specimens from the Bacia de Campos, the distribution of T. agathida can now be extended in the Brazilian coast from 7º to 22º S.

Hexactinellid Sponges

Descriptions of hexactinellid sponges collected by the RV ‘Marion Dufresne’ MD55 expedition on the Vitória–Trindade seamounts chain (off Espírito Santo State, south-eastern Brazil) in 1987 and stored in the MNHN (Muséum National d'Histoire Naturelle in Paris) are presented. Hyalonema (Cyliconema) conqueror sp. nov. (the first finding of this subgenus in the Atlantic Ocean) and H. (Prionema) dufresnei sp. nov. (the second record of this subgenus for the Atlantic Ocean) are described as new species. The holotype of H. (C.) conqueror sp. nov. was collected with a ROV at Campos Basin (off Rio de Janeiro State, south-eastern Brazil), while the paratypes originated from Vitória–Trindade seamounts chain and off Bahía State (eastern Brazil). Other hexactinellids reported here, Farrea sp., Sarostegia aff. oculata, Aphrocallistes aff. beatrix, Dactylocalyx aff. subglobosus and Euplectella suberea were known before to be widely distributed in the Atlantic Ocean. The total number of hexactinellid sponges known from Brazil has risen to 15 and from the south-western Atlantic to 23.

The Brazilian expeditions REVIZEE Central Fishery and Campos Basin Deep Sea Environmental Project collected samples from the southwestern Atlantic, between depths from 200 to 2200m. These expeditions sampled three Plesionika Bate, 1888 species: Plesionika edwardsii (Brandt, 1851), P. ensis (A. Milne Edwards, 1881) and P. miles (A. Milne Edwards, 1883). Besides that, one species of Stylopandalus Coutiére, 1905, a genus never recorded on Brazilian coast before, was collected. These four pandalids were redescribed and figured.

Cryptogenic Species

Bioeroding sponges of theCliona viridisspecies complex play a large role in carbonate cycling and reef health. In the present study we provide the first record and a description of a Mediterranean lineage ofC. viridis(Schmidt, 1862) in the south-western Atlantic. Specimens were collected in Maricás Archipelago, Rio de Janeiro State in September 2010 by scuba diving at 10–12 m depth and deposited in the Porifera collection of Museu Nacional, Universidade Federal do Rio de Janeiro. Morphologically, the specimens presently examined are very similar to those described in the beta and gamma growth form from the Mediterranean. The Brazilian and Mediterranean specimens share large and irregular papillae over 2 cm in diameter, megasclere tylostyles up to 500 µm long and microsclere spirasters with up to five twists and 34 µm long. A Maximum Likelihood analysis of 28S rDNA ofC. viridis, C. aprica, C. jullieni, C. schmidtiandC. varianswas performed for a genetic identification of the Brazilian specimens. The Brazilian material is phylogenetically closer to the MediterraneanC. viridisthan to the Caribbean and Indian Ocean members of this species complex included in the present analysis. Our results suggest thatC. viridisis a cryptogenic species with a distribution extending from the Mediterranean to the eastern Atlantic and in the SE Brazilian coast or further.

Two larval Symphysanodon, collected off the coast of Rio de Janeiro, southern Brazil (at 22º32’50.0” S, 040º04’09.0” W), beyond the 1,000 m isobath, are the first specimens of the monotypic family Symphysanodontidae to be reported from the western South Atlantic Ocean. We are unable to assign the larvae to a described species and entertain the idea that the Brazilian material may represent an undescribed species.

Copepod crustaceans of the genusGaussiainhabit open ocean waters in epipelagic and bathypelagic zones from 0 to 5000 m. They show high-speed vertical migration and bioluminescent characteristics. In the Atlantic Ocean only the speciesG. asymmetricaBjörnberg T. K. S. & Campaner, 1988 andG. princeps(Scott T., 1894) have been recorded previously. We report the first occurrence of the rarely recordedG. intermediaDefaye, 1998 for the Atlantic off Brazil. The specimens were collected around the Rocas Atoll (3°51′S 33°49′W), through the ABRAÇOS (Acoustic along the BRazilian COast) project on board R/V “Antea” in October 2015, using a micronekton net (mesh size 1 mm) and oblique hauls. Five specimens were collected at Rocas Atoll, in depths of 510-525 m. This finding expands the global distribution ofG. intermediaand is the first occurrence in the Atlantic Ocean, updating the checklist of meso-bathypelagic copepods for Brazilian waters.

Recent studies reported the introduction of non-native species on the Brazilian coast. In this contribution, we provide the first record of Cephalopholis taeniops (Valenciennes 1828) in the western South Atlantic, based on a specimen captured off the Ilhas Cagarras, Rio de Janeiro, Brazil, and discuss the potential agents for its introduction. While this single specimen was collected in 2006 in a well-known locality, no other specimen has been captured since.

Until now only six species of lithodids have been found occasionally in the Brazilian coast. Most king crabs are accidentally caught during fisheries targeting other species. Herein we report new records forLithodes confundensandNeolithodesaff.asperrimusfrom the south of Brazil, from the states of Rio Grande do Sul and Santa Catarina, respectively.Lithodes confundensis found in the western Atlantic with a previous northern limit in the Province of Buenos Aires, Argentina.Neolithodesaff.asperrimusis known to occur only along the western coast of Africa in the eastern Atlantic and this is the first record of the species in the western Atlantic.
