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.

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 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.

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.

A new species of Trischizostoma collected at depths of 1392–1420 m from western Mexico is described. It represents the first record of the genus in the NE Pacific. The new species is morphologically similar to T. circulare, T. tohokuense and T. richeri. These species all share a large rostrum, expanded eyes and an entire telson. Distinctive characters of the new species include a dorsally unnotched urosomite 1, a subconical coxa 2, a subtriangular propodus of gnathopod 1, a single seta and one protuberance on the palm of gnathopod 2, the presence of 10 spine-teeth in the outer plate of maxilla 1 and of a large, 1-articulate maxilla 1 palp, and the telson with 2 minute simple setae and 2 minute projections distally.

Deep-sea pycnogonid material collected during the N/O Alis Campagnes Norfolk 2 to New Caledonia in 2003 and Salomon 2 to the Solomon Islands in 2004, together with two samples from the BOA0 and BOA1 Campagnes to Vanuatu in 2004–2005, has been analyzed. This includes only the second collection of deep-sea pycnogonids from the Solomon Islands. The material includes 22 specimens from seven species from New Caledonia, taken at depths from 265 to 1150 m, 95 specimens from 14 species from the Solomon islands, at depths from 336 to 1218 m, and two specimens of one species from Vanuatu (864–927 m depth). The first male of Ascorhynchus constrictus is described, including the first description of the anterior legs. A new species of Ascorhynchus is partially described, but not named owing to its incompleteness. Seven of the species are new to the Melanesia region, including a notable range-extension for Colossendeis tasmanica. The local zoogeography of these deep-water species is discussed.

High Diversity

Acteonidae d'Orbigny, 1843 is the largest family within the superfamily Acteonoidea (Bouchet et al. 2017) and includes small gastropods typical of infralittoral environments. Most acteonids living on the continental shelf or in deep water have been described on the basis of shell morphology alone (Simone 2006; Valdés 2008; Cunha 2011; Salvador & Cunha 2016), because little material with soft parts has been collected and examined. Consequently, little is known about the ecology of the species.  Recently, many new species of the genus Acteon Montfort, 1810 have been described from tropical Southwest Pacific waters (Valdés 2008), suggesting that a high diversity of acteonid species may await discovery in other deep water environments, including those of Brazil.

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).

Heteroclinus argyrospilos, n. sp. is described as a new species from specimens sampled by sled and dredge in 55–100 m off South Australia and Western Australia. The species has a strongly compressed body and spatulate orbital tentacle similar to some shallow water species, particularly those of the Heteroclinus heptaeolus complex, which is characterized by having three segmented dorsal-fin rays, with the last two rays widely separate from the first ray. It is distinct from other Australian clinids in having two segmented dorsal-fin rays, well separated from the last dorsal-fin spine and a reduced lateral line on the body. It is known from a greater depth than other members of the genus.

A New Species

The Hengduan Mountains, as one important biodiversity hotspots in the world, is notable for its high habitat heterogeneity and extreme plant diversity which including many endemics species. Incarvillea uniflora, a new species is described from Hengduan Mountains. The new species is similar to I. himalayensis in having red corolla, stemless, solitary flower, capsule 4-angled and winged seeds, but differs by the characters of stable simple leaves, long triangular calyx lobes and solitary or clustered flowers. It is considered to be Data Deficient (DD) due to the lack of further field investigation.
