Antipatharians are still poorly documented in the southeastern Pacific, with just eleven species reported in Chilean waters, all of them distributed in subtidal areas from 70 to 2000 m depth (Häussermann & Försterra, 2007; Cañete & Häussermann, 2012; Araya et al. 2016a). Among the family Schizopathidae Brook, 1889, which is characterized by polyps elongated in the direction of the axis and having a transverse diameter of 2 mm or more (Opresko, 2002), the recently described deep-water genus Alternatipathes Molodtsova & Opresko, 2017, encompasses two recognized species, Alternatipathes alternata (Brook, 1889), reported from abyssal basins (2670 to 5089 m depth) of the Indian and Pacific Oceans, and Alternatipathes bipinnata (Opresko, 2005), known from a few specimens collected in deep waters (1130 to 2846 m) off the Pacific coasts of northern Mexico and southern USA (Opresko, 2005; Molodtsova & Opresko, 2017).

Neomormonilla minor (Giesbrecht, 1891) is a small planktonic copepod distributed widely in intermediate and deep waters of the ocean, mainly at depths of 400-1000 m. The species was reported earlier only for the tropical Pacific Ocean (Central America, Galapagos Islands, and north of Peru). The present study provides the first record of females of the species for the southeastern Pacific, i.e., in the Humboldt Current System off the coast of northern Chile (23-27°S). Here we describe and illustrate the taxonomic characteristics of this species that will allow its identification and differentiation with respect to other species of the genus and of the family Mormonillidae.

Prochelator tupuhi sp. nov. is the first record of the genus Prochelator Hessler, 1970 from Southern Hemisphere waters, and the first record of the family Desmosomatidae from New Zealand. The new species can be distinguished from all other species of the genus by the following characters: body elongate, without spine-like ventral elongations on pereonites 1–4, pereonite 1 as high as pereonite 5, mesial lobe of the maxilla much shorter than in the other species of the genus, reaching only half the length of the lateral lobe, carpus of pereopod 1 distinctly produced at the base of the claw, propodus broadest at the articulation to the carpus, tapering distally.

Chalinidae is a family of haplosclerid sponges with a delicate reticulated chaonosomal skeleton of uni-, pauci- or multispicular primary lines which are connected by unispicular secondary lines, and with an ectosomal skeleton, if present, formed by a regular hexagonal, unispicular, tangential reticulation (Weerdt 2002). Currently, the family harbors only five valid genera (Chalinula, Cladocroce, Dendrectilla, Dendroxea and Haliclona; Soest et al. 2008), although recent molecular studies suggest that a new rearrangement of the present classification is needed (Redmond et al. 2007). Cladocroce was described by Topsent (1892) from specimens collected in the Atlantic Ocean. The principal characteristic of this genus is the presence of multispicular fiber tracts with a rather dense subisotropic reticulation in between (Weerdt 2002). After that, 10 species have been described, most of them from deep waters and cold climates (Putchakarn et al. 2004). Only three species have been found living in shallow waters: C. aculeata Pulitzer-Finali, 1982 from the Great Barrier Reef, C. burapha Putchakarn et al., 2004 from the Gulf of Thailand, and C. tubulosa Pulitzer-Finali, 1993 from the port of Mombasa, in Kenya. Sponge taxonomy studies in the Mexican Pacific coast have been focused mainly on hadromerids, and particularly on boring sponges (Carballo et al. 2008), and the current knowledge of haplosclerids is very scarce (Cruz-Barraza & Carballo 2006). In this paper, a new species of Cladocroce is described and compared with the other species recorded worldwide. With this contribution the genus Cladocroce increases to 12 species.

Upeneus stenopsis n. sp. is described based on four specimens collected off northern Australia and Quezon Island,Philippines, at depths between 165 to 275 m and compared with four closely related species: the deep-water dwellingUpeneus davidaromi (Red Sea) and U. mascareinsis (Western Indian Ocean) and the shallow Indo-West Pacific species,U. subvittatus and U. vittatus. The new species can be distinguished from all other Upeneus species by a narrow caudalpeduncle and a combination of morphometric and meristic characters. This is the first record of a deep-water goatfish ofthe genus Upeneus from the Pacific. A juvenile Upeneus collected off Quezon at 127–142 m depth was also assigned tothe new species and compared to four similar-sized (69–79 mm SL) specimens of U. mascareinsis. A diagnosis is providedfor U. subvittatus, along with evidence of its occurrence in the Eastern Indian Ocean and interspecific comparisons. Thecontinued need to screen scientific fish collections for the occurrence of undescribed species that have successfully colonized and adapted to the depth zone surrounding the ocean margin is outlined.

Collections made along the coast of California have revealed the presence of a species of Pseudosphaeroma Chilton, 1909, a genus common in New Zealand coastal waters. The genus is entirely Southern Hemisphere in distribution, and this record reports the introduction of a species of Pseudosphaeroma into the San Francisco and Central Coast region of California, the first reported occurrence of the genus as an invasive taxon, and the first record of the genus from the Northern Hemisphere. The genus is also recorded for the first time from the Galapagos and Argentina.

Psychrolutes sio, a new species of Psychrolutidae from off northernmost Chile, is described from two specimens trawled at about 770–1150 m. The holotype is deposited in the Scripps Institution of Oceanography (SIO 72-184). The only large specimen, the 22.9-cm holotype, differs most conspicuously from the other two species of the genus Psychrolutes in having the head and body color a uniform brown, skin thin, lateral line pores in small but distinct tubes, and jaws equal. Psychrolutes sio represents the first record of the genus Psychrolutes to be recognized from the Southern Hemisphere. However, future studies may indicate that other southern psychrolutids of the genera Neophrynichthys and Cottunculoides should also be assigned to Psychrolutes.

Mexicope sushara sp. nov. is recorded from southeastern New Zealand coastal waters, the first record of the genus from the Pacific and the first record of the Acanthaspidiidae from New Zealand. The species is from the continental shelf, taken in association with a bryozoan colony at a depth of 80 metres on the Otago Shelf, southeastern South Island. The distinguishing characters are a rostral spine and prominent and acute pre-ocular lobes; these characters in conjunction with stalked eyes separate the species from all others in the family.

Several filamentous endophytic genera are assigned to the Phaeophyceae, in particular to the family Chordariaceae (Cormaci et al. 2012). Brown endophytic filamentous algae are known to cause infections in host marine algae (Schoenrock et al. 2013; Ogandaga et al. 2016, 2017; Gao et al. 2019). Acting as pathogens, they may cause morphological, physiological and ecological changes in the host alga such as production of galls and wart-like spots, changes in metabolism and growth rates, and changes in survivorship and reproduction (Schoenrock et al. 2013; Ogandaga et al. 2016, 2017; Gao et al. 2019). Among brown algal filamentous endophytes, the genus Mikrosyphar Kuckuck is relatively understudied. To date, only Mikrosyphar zosterae Kuckuck (1895: 177) was studied thoroughly (Ogandaga et al. 2016, 2017).

A new genus and a new species, Haplodendron buzwilsoni, from the southeastern Australian mid bathyal are described. This is the first record of the family in the Southern Hemisphere IndoPacific. Diagnostic characters of the new genus are compared with those of other genera in the family. The possible significance of the joint possession, between the new genus and Dendrotion (Dendrotiidae), of a stalk carrying the antennulae and antennae is discussed. New observations on male reproductive structures are made.

Thambema thunderstruckae sp. n., the first record of Thambematidae (Isopoda: Asellota) from the Southern Hemisphere shelf A new thambematid species, Thambema thunderstruckae sp. n., is described from King George Island, South Shetland Islands, Antarctic. Specimens of the new species were collected during two Polish Antarctic Expeditions in 1985 and 2007. It is the first record of this family from the Southern Hemisphere. The new species most closely resembles Thambema golanachum Harrison, 1987 and T. fiatum Harrison, 1987 but can be distinguished from both species by the shape of male pleopod 1, the number of claws on pereopods 2-7 and the setation of pereopod 1 and 2 carpus, respectively. A key to all known genera and species in the family Thambematidae is also provided.
