The genus Opaliopsis from Brazil is revised based on three deep-water species. Opaliopsis atlantis (Clench & Turner, 1952) is confirmed as occurring in north-eastern and south-eastern localities. Opaliopsis opalina (Dall, 1927) is reported for the first time in the south-western Atlantic. A new species, Opaliopsis cearense, is described from the north-eastern Brazilian coast, and is distinguished by its large number of fine spiral cords per teleoconch whorl.

Bougainvillia aberrans n.sp. is described from Bermuda in the western North Atlantic Ocean. Specimens were collected at a depth of 150 fathoms (274 m) from the polypropylene buoy line of a crab trap. The hydroid colony of B. aberrans is erect, with a polysiphonic hydrocaulus, a smooth to somewhat wrinkled perisarc, hydranths having a maximum of about 16 tentacles, and medusa buds arising only from hydranth pedicels. Medusae liberated in the laboratory from these hydroids differ from all other known species of the genus in having a long, spindle-shaped manubrium, lacking oral tentacles, having marginal tentacles reduced to mere stubs, and being very short-lived (surviving for a few hours at most). Gonads develop in medusa buds while they are still attached to the hydroids, and gametes are shed either prior to liberation of the medusae or shortly thereafter. The eggs are surrounded by an envelope bearing nematocysts (heterotrichous microbasic euryteles). The cnidome of both hydroid and medusa stages consists of desmonemes and heterotrichous microbasic euryteles. The diagnosis of the genus Bougainvillia is modified to accommodate this new deep-water species.

A new genus and species in the caridean shrimp family Palaemonidae is described based on three type specimens collected at a depth range of 208–385 m off Guadeloupe, French Antilles. Zoukaris festivus gen. et sp. nov. shares many characters with several western Atlantic deep-water species currently assigned to Periclimenes Costa, 1844, as well as with the monotypic western Atlantic genus Diapontonia Bruce, 1986 and the Indo-West Pacific genus Echinopericlimenes Marin & Chan, 2014. Zoukaris gen. nov. can be separated from all of them by a unique combination of morphological features, especially the configuration of the dactylus of the ambulatory pereiopods. In addition, Periclimenes milleri Bruce, 1986 is recorded from the French Antilles based on a single specimen, also from Guadeloupe; its colour pattern is illustrated for the first time.

Four deep-water species of stalked barnacles were collected by the manned submersibles Jiaolong and Shenhaiyongshi during recent expeditions. Trianguloscalpellum regium (Wyville-Thomson, 1873), collected from the Mariana Trench at a depth of 5,462 m, represents a new distribution record. Glyptelasma gigas (Annandale, 1916), Poecilasma litum Pilsbry, 1907 and Poecilasma obliqua Hoek, 1907, collected from the South China Sea, are recorded for the first time from a mud volcano environment. Detailed photographs of these four species are presented and their partial sequences of 16S rRNA and mt COI genes are provided.

A new species of deep waterEpimeriais described based on material collected in 1526–1586 m depth during the TALUD X expedition in the central Gulf of California, Mexico. It is the sixth species of this genus reported for the East Pacific.Epimeria morroneisp. nov. is morphologically similar toE. norfanziLörz, 2011 (New Zealand, 1268 m depth) andE. coraJ.L. Barnard, 1971 (off Oregon, USA, 2086 m depth).Epimeria morroneisp. nov., however, differs from these two species by a combination of several characters, including: vestigial eyes; multidentate mandibular lacinia mobilis; a distinct setae arrangement in palm and dactylus of gnathopods 1–2; the shape and relative size of coxae 1–5; and the shape of the telson.

A New Species

Most lithistids occur worldwide in deep-water environments, but can be found in some places in shallow water. They are not well known in the tropical western Atlantic, despite the fact that they were first described in the late 1800s. We report here two species of poorly known theonellid demosponges (Astrophorina), Discodermia dissoluta and Theonella atlantica, and one new species, Theonella wrightae, from the north-west, south-west and south Florida shelf. There is considerable variability in habitus, colour and spiculation in this species. If samples are taken randomly from different specimens and from functionally and structurally different locations on the sponge, the specimens could be mistakenly identified or individuals of the same species could be described as different species. This report increases the number of lithistid sponges reported from the tropical western Atlantic region to 30 species, but our unpublished data suggest a much higher number of species present in this region. It is also the second report of the relatively deep-water (81 m) occurrence of D. dissoluta that is mostly known from depths as shallow as 10–30 m.

A new deep-water species of the snapping shrimp genus Alpheus Fabricius, 1798 is described from two offshore localities in the northern Gulf of Mexico, south of Louisiana. Alpheus lentiginosus n. sp. belongs to the A. macrocheles (Hailstone, 1835) species group and is most closely related to the western Atlantic A. pouang Christoffersen, 1979 and A. amblyonyx Chace 1972, the eastern Atlantic A. platydactylus Coutière, 1897 and A. macrocheles (Hailstone, 1835), and perhaps also to the eastern Pacific A. exilis Kim & Abele, 1988. The new species is associated with deep-water soft sediments adjacent to clusters of Lophelia pertusa (L.) (Scleractinia) or mud-covered rocks and cobble, at a depth range of 336–438 m, thus representing the deepest-known record of the Alpheidae in the Gulf of Mexico and the entire western Atlantic.

Nongeniculate calcareous algae are bio-constructors of many marine habitats, some of which are considered biodiversity hotspots. The genus Sporolithon is widely distributed around the world. As part of a review of material from the Brazilian continental shelf we found Sporolithon episoredion, that extend its distribution range into the Atlantic Ocean, Sporolithon ptychoides, which is widely distributed across oceans, and a new species of this genus named Sporolithon elevatum sp. nov. This species presents sorus 2–3 cells elevated above the thallus that sloughs off when senescent, paraphyses with 2–3 cells and a basal layer of elongated cells in areas where sporangia develop. The new species was found at 133 m depth. This study contributes to the understanding of the diversity in this genus and indicates the importance of systematic studies in the framework of conservation programs and evaluation of impacts in an area under exploitation activities.

Zooplankton samples from inland water bodies in the north-eastern part of Borneo were collected in rivers, ponds, roadside ditches, irrigation canals, rice fields, and temporary water bodies. The harpacticoid copepods (Harpacticoida) were found only in three surveyed locations. Seven species of four genera from the families Canthocamptidae and Phyllognathopodidae were identified. Four of harpacticoid species found belong to the genus Elaphoidella. A new species, Elaphoidella fatimae sp. nov., is described. It differs from all known species of the genus by combination of the following characters: posterior margins of body somites serrate at dorsal side; anal operculum rounded, with spinules; caudal rami conical; exopod of leg 5 about three times as long as wide. Six species were reported for Borneo for the first time.

A neotype is designated for Chemnitzia puncta C. B. Adams, 1850, now placed in the genus Turbonilla and considered to be a senior synonym of Turbonilla peilei Dall & Bartsch, 1911, Turbonilla haycocki Dall & Bartsch, 1911 and Turbonilla alfredi Abbott, 1958. Turbonilla obsoleta Dall, 1892, described as a variety of T. puncta, exhibits great deal of intraspecific variation in shell morphology and is considered as valid at the specific level. Turbonilla deboeri Jong & Coomans, 1988, Turbonilla westermanni Jong & Coomans, 1988 and Turbonilla punicea Dall, 1884 share a spiral sculpture pattern very similar to T. puncta, differing in the outline of the whorls, details of the ribs and/or width of the protoconch. Turbonilla puncta, T. deboeri, T. obsoleta and T. westermanni are reported for the first time from the Brazilian coast. Turbonilla tupinamba n. sp. is described from the southeast coast of Brazil and is distinguished from the conchologically related T. puncta and T. deboeri, by the shape of the ribs, outline of the whorls and growth pattern of the shell.
