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.

This paper reports the occurrence of four deep waters shrimps of the family Solenoceridae in the southwestern Atlantic, Brazil. The rare Hadropenaeus modestus is collected for the second time from Brazilian waters after 138 years, filling the gaps on its distributional pattern. Mesopenaeus tropicalis is a new register for Potiguar basin, although it is common along Brazilian coast. Hymenopenaeus chacei and H. laevis are recorded for the first time in southwestern Atlantic. The records of these species in the southwestern Atlantic are an important advancement to raise the knowledge of the deep-sea shrimps.

Available Information

In this paper, we provide some available information about the occurrence and some taxonomic aspects of 19 species from the Superfamily Oplophoroidea in the southwestern Atlantic (Brazilian waters), with the update to 22 species of Oplophoroidea occurring in Brazilian waters. Samples were collected during two sets of surveys. The first was performed in 2009 and 2011 in the Potiguar Basin in northeast of Brazil (03–05°S; 38–35°W; between the States of Ceará and Rio Grande do Norte) under the framework of the project “Avaliação da biota bentônica e planctônica da Bacia Potiguar e Ceará (Bpot)”, with samples collected from bottom trawls in the continental slope at depth ranging from 150–2068 m. Second, under the in the framework of the ABRACOS (Acoustic along the Brazilian coast), performed in 2015 and 2017 on seamounts and offshore areas in Northeast Brazil (Ceará Chain, Rio Grande do Norte and Rocas Atoll, Fernando de Noronha Archipelago and Pernambuco State), with samples with pelagic micronekton and mesopelagic nets, in depths ranging from 50–1260 m. We highlight the occurrence of 14 species of the family Acanthephyridae and 5 species of the family Oplophoridae, including the first occurrences of five species to Brazilian deep waters: Acanthephyra kingsleyi Spence Bate, 1888, Ephyrina ombango Crosnier & Forest, 1973, Meningodora compsa (Chace, 1940), M. longisulca Kikuchi, 1985 and Systellapsis curvispina Crosnier, 1987. These records increase the knowledge on deep-sea shrimps occurring in Southwestern Atlantic.

Four new species of the genus Cymadusa are described from Brazil (states of Ceará, Espírito Santo and Rio de Janeiro). Cymadusa icapui is described from Ceará state, C. trindadensis is described from Espírito Santo state, C. rasae and C. tartarugae are described from Rio de Janeiro state. Two identification keys are presented: one to all known species of the family Ampithoidae from Brazil, and another one to world species of Cymadusa. Based on literary review and analysis of collection material, we extend the distribution of Cymadusa filosa Savigny, 1816 along the Brazilian coast by finding new location records of the species based on analysis of stored collection material.

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).

First Time

The present study reviews the taxonomy of the marine gastropods belonging to the family Eulimidae Philippi, 1853 from the continental slope off Northeast Brazil. The genera Abyssoaclis Barros, Mello, Barros, Lima, Santos, Cabral & Padovan, 2003 and Aclis Lovén, 1846 were not treated here. A total of 20 taxa were identified in this region, excluding Eulima hebes Watson, 1883, a species with a doubtful classification in Eulimidae. The species were assigned to the following genera: Costaclis Bartsch, 1947, Eulima Risso, 1826, Fusceulima Laseron, 1955, Melanella Bowdich, 1822, Ophieulima Warén & Sibuet, 1981, Sticteulima Laseron, 1955, Thaleia Warén, 1979, and Umbilibalcis Bouchet & Warén, 1986. The genera Sticteulima, Ophieulima and Umbilibalcis are reported for the first time in the southwestern Atlantic. Four species represent new records for the southwestern Atlantic. A redescription of the shell morphology is provided for: Costaclis egregia (Dall, 1889b), Melanella doederleini (Brusina, 1886), and Umbilibalcis lata (Dall, 1889b). Additional information to the original description are reported for other species. Melanella sarissa is considered as a synonym of Melanella cinca Dall, 1927. Six new species are described: Eulima cracentis sp. nov., Melanella paraabida sp. nov., M. adiastalta sp. nov., M. anapetes sp. nov., Sticteulima cabrali sp. nov. and S. canopusensis sp. nov. Lectotypes are designated for: Costaclis hyalina, C. egregia, Eulima ephamilla (Watson, 1883), E. psila and E. (?) hebes. Eulima sp. 1, Melanella sp. 1 and Melanella sp. 2 are potential new species, but the scarcity of material precludes a formal description at this moment.

Emended Diagnosis

A new species of the genus Cephalanticoma is described for the Atlantic Ocean in the Potiguar Basin off the continental shelf of northeast Brazil. Cephalanticoma rugatusa sp. n. is characterized by bearing head capsule ending on the level of amphideal fovea, a tubular precloacal supplement and two rows of thin precloacal setae. Cephalanticoma rugatusa sp. n. differs from all other species of the genus by having a precloacal cuticular papilla in front of the cloaca and a cuticular transversal wrinkle which extends from the papilla elevation to the conical-cylindrical portion of the tail occupying both subventral regions. An emended diagnosis and a dichotomous key to species based on both genders are provided.

Three New Species

A diverse eutardigrade fauna of the family Eohypsibiidae Bertolani & Kristensen, 1987 was collected on the Faroe Islands. The first record of Bertolanius weglarskae (Dastych, 1972) and new records of Eohypsibius nadjae Kristensen, 1982 are documented. The new genus Austeruseus is established and three new species, Austeruseus faeroensis, nov. sp., A. balduri nov. sp. and A. rokuri nov. sp. are described. The genus differentiates from the genera Bertolanius and Eohypsibius in the buccal tube. The apophyses for the insertion of stylet muscles are (two or six) lateral hooks and the entire length of the mouth and buccal tube are straight in Austeruseus, while Bertolanius and Eohypsibius have the apophyses for the insertion of stylet muscles as crests with ventral and dorsal hooks, and the mouth and buccal tube are flared or trumpet shaped. With five species the Faroese tardigrade fauna is the richest in the world with regard to the family Eohypsibiidae. The genus Austeruseus is primarily found in mosses at high mountain biotopes, and the new genus may be a glacial relic.

Two New Species

Two new species of Aclis Lovén, 1846 are described from the continental slope of northeast Brazil. Aclis macrostoma n. sp. is recorded off the state of Rio Grande do Norte at depths ranging from 375 to 510 meters. Aclis watsoni n. sp. was dredged off the state of Sergipe at depths ranging from 365 to 510 meters. There are no similar species along the Brazilian coast. Aclis watsoni is similar to Aclis angulata Smith, 1890, Aclis trilineata Watson, 1897, Aclis supranitida (Wood, 1842) and Aclis ascaris (Turton, 1819) due to the presence of spiral keels and/or indication of a subsutural ramp. Aclis macrostoma is similar to Discaclis canariensis Moolenbeek & Warén, 1987, Aclis attenuans Jeffreys, 1883 and Aclis gulsonae (Clark, 1850) regarding its circular aperture and dilatation of the peristome, with a non-thickened outer lip. The latter two species are much more slender.
