Six new species of the family Ampeliscidae Costa, 1857 are described from Campos Basin Deep Sea in Brazilian Cost. The four new species of the genus Ampelisca herein described, Ampelisca wakabarae sp. nov., Ampelisca campensis sp. nov., Ampelisca anae sp. nov., Ampelisca minuta sp. nov. raised the total number of species of this genus recorded along the Brazilian coast to 14. Others species described are: Byblis bjornbergae sp. nov. and Haploops meloi sp. nov. These are first records of these genera for Brazilian coast. A key to the species of the family Ampeliscidae recorded from Brazilian coast is provided.

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.

A New Species

Sponges of the Family Pachastrellidae Carter, 1875 are distributed worldwide and found generally in deep water. Up to date, only four species are known for the Brazilian coast (Muricy 2018): Characella aspera Sollas, 1886, C. capitolii Mothes et al. 2007, C. pachastrelloides (Carter, 1876), and Pachastrella monilifera Schmidt, 1868. In this study, a new species of Characella is described from the mesophotic zone off Bacia Potiguar (Rio Grande do Norte State, Northeastern Brazil). The specimen was preserved in 80% ethanol and deposited in the Porifera Collection of the Universidade Federal de Pernambuco (UFPEPOR). Taxonomic comparisons were made with data tabulated for all species of Characella available in the World Porifera Database (van Soest et al. 2018).

Three New Species

Two new genera and nine new species of hydroids are described based on deep-water material collected from off New Caledonia during various expeditions of the French Tropical Deep-Sea Benthos program. Caledoniana gen. nov., provisionally included in the family Sertulariidae Lamouroux, 1812, presently comprises three new species, viz. C. alata sp. nov., C. decussata sp. nov., and C. microgona sp. nov., while an additional group of three new species, is accommodated in the new sertulariid genus Solenoscyphus gen. nov.: S. candelabrum sp. nov., S. decidualis sp. nov., and S. striatus sp. nov. Furthermore, three new species of Hincksella Billard, 1918 (family Syntheciidae Marktanner-Turneretscher, 1890) are described, namely H. cornuta sp. nov., H. neocaledonica sp. nov., and H. similis sp. nov.

The World

The family Hormathiidae Carlgren, 1932 is one of the largest families of sea anemones with ca. 130 species around the world, mostly in the deep sea. In Brazilian waters, only six species have been reported so far. Herein we record four hormathiids from deep-sea sites at the Potiguar Basin continental slope at Northeast Brazil. Monactis vestita (Gravier, 1918) and Phelliactis robusta Carlgren, 1928 represent the first records of both genera for the Brazilian coast. The new species Paraphelliactis labiata n. sp. is described. We also found another species of the genus, Phelliactis sp. The new species possesses fourth and fifth cycles of incomplete mesenteries, unlike all other Paraphelliactis species. These results increase the total number of hormathiid sea anemones in Brazil to nine and contribute to the knowledge of the Brazilian deep sea, still little explored.

A New Species

A new amphipod species of the genus Elasmopus Costa, 1853 is described based on material collected from intertidal rocky shore, near the Suape Harbor, coast of the Brazilian state of Pernambuco. The new species may be recognized by the propodus of gnathopod 2 suboval, slightly tapering distally, palmar margin not defined by a stout seta, spine, or palmar corner, with a subdistal blunt tubercle, posterior margin covered by a dense fringe of plumose setae, and posterior margin of basis of pereopod 7 castelloserrate. This is the ninety-fifth species of the genus Elasmopus described worldwide, the most diverse genus in the family Maeridae Krapp-Schickel, 2008, and the eighth species recorded from Brazilian waters. An identification key to Brazilian species of Elasmopusis also provided.

The Status

The family Harrimaniidae (Hemichordata: Enteropneusta) is revised on the basis of morphological characters. The number of harrimaniid genera is increased to nine by the addition of Horstia n. gen., Mesoglossus n. gen., Ritteria n. gen. and Saxipendium, a genus previously assigned to the monospecific family Saxipendiidae. The number of species is increased to 34, resulting from the description of five new species from the eastern Pacific — Horstia kincaidi, Mesoglossus intermedius, M. macginitiei, Protoglossus mackiei and Ritteria ambigua. A description is supplied for a sixth harrimaniid species, Stereobalanus willeyi Ritter & Davis, 1904, which previously had the status of a nomen nudum. Four harrimaniids previously assigned to the genus Saccoglossus are transfered to the genus Mesoglossus — M. bournei, M. caraibicus, M. gurneyi and M. pygmaeus, while Saccoglossus borealis is reassigned to the genus Harrimania. Notes on habitat and zoogeography are included for the seven foregoing species and a table of diagnostic characters for existing and new species and a dichotomous key to the enteropneust families and harrimaniid genera are provided. Finally, a phylogenetic hypothesis concerning the Harrimaniidae is postulated, with discussion on the evolution of the group.

The Moment

Four new species of Cumacea are described from deep-sea samples collected around Salomon Islands during the French campaign SALOMON I. Bathylamprops pagesi sp. nov. and Bathylamprops caperatus sp. nov. belonging to the family Lampropidae differ from the all currently known species by the oblique lateral carina running from anterolateral angle backwards. The nannastacid Campylaspis alisae sp. nov. can be identified by the shape of the carapace carinae, especially in dorsal view. The diastylid Oxyurostylis? salomonensis sp. nov. due to the lost of the telson tip, is difficult to assign either to the genus Diastylis Say, 1818 or to the genus Oxyurostylis Calman, 1912. At the moment, it is included provisionally to the genus Oxyurostylis and it differs from the other species in the genus by its flattened eyelobe and the higher number of setae on telson.

Deep Sea Sediments

A new genus and species of Desmodoridae was found in deep-sea sediments of the Campos Basin. Although the cuticle annulation of the new species is similar to members of Desmodorinae, many morphological features are strong enough to classify it within the Spiriniinae. Spirodesma magdae nov. gen. nov. sp. is characterized mainly by the presence of a unique form of unispired amphids, with circular amphideal fovea, and a buccal cavity with three equal teeth, one dorsal and two ventrosublateral.
