New material collected from the Western Pacific has necessitated a revision of family Podospongiidae and the establishment of two new genera, Neopodospongia gen. nov. and Diplopodospongia gen. nov. Neopodospongia gen. nov. was established for a group of sponges characterised by a leathery ectosome, strongyloxeas, aciculospinorhabds, and sigmoidal protospinorhabds. Diplopodospongia gen. nov., was established for a group of thinly encrusting deep-water sponges that have anisoxeas and dumbbell-shaped spinorhabds. Eight new species of Podospongiidae are described here: two species of Podospongia du Bocage, 1869; P. virga sp. nov., from northern New Zealand and P. colini sp. nov., from Indonesia, three species of Neopodospongia from New Zealand; N. pagei gen. nov. sp. nov., N. bergquistae gen. nov. sp. nov., and N. exilis gen. nov. sp. nov., and three species of Diplopodospongia; D. rara gen. nov. sp. nov. and D. teliformis gen. nov. sp. nov. from New Zealand, and D. macquariensis gen. nov. sp. nov. from the Australian Exclusive Economic Zone surrounding Macquarie Island in the Southern Ocean. In addition, the Irish encrusting sponge P. normani (Stephens 1915) has been reassigned to Neopodospongia gen. nov. An updated identification key to Podospongiidae genera is included.

Three new genera and five new species of epialtid majoid crabs are described from deep water in the western Pacific. Two new species of Oxypleurodon Miers, 1886: O. sanctaeclausi n. sp. and O. annulatum n. sp. are described from the Philippines. New specimens of the rare Oxypleurodon carbunculum (Rathbun, 1906) from the Hawaiian Islands are also recorded. Three new genera are established: Garthinia n. gen. for G. disica n. sp. from the Solomon Islands; Guinotinia n. gen. for G. cordis n. sp. from New Caledonia and G. lehouarnoi n. sp. from Fiji and Tonga; and Laubierinia n. gen. for Sphenocarcinus nodosus Rathbun, 1916, and Rochinia carinata Griffin & Tranter, 1986.

Two new genera and five new species of Selachinematidae are described from the New Zealand upper continental slope (350-1240 m depth). Synonchiella rotundicauda sp. nov. is characterised by cephalic setae 0.25 cbd long, mandibles each with two pairs of hooks and two wing-like projections laterally, eight cup-shaped pre-cloacal supplements and short rounded tail. Pseudocheironchus gen. nov. is similar to Cheironchus, but differs from the latter in having a cuticle without lateral differentiation, cephalic setae only slightly longer than the outer labial sensillae, and a posterior buccal cavity with three equal mandibles. Pseudocheironchus ingluviosus gen. et sp. nov. is characterised by mandibles with eight blunt teeth, multispiral amphideal fovea with five turns, and a short rounded tail. Males of this new species with 17-19 cup-shaped pre-cloacal supplements. Males of the genus Cobbionema are described for the first time; C. trigamma sp. nov. is characterised by four long cephalic setae and six smaller outer labial setae in one circle, six rhabdions surrounding the anterior buccal cavity, each with two pairs of pointed projections at their posterior extremities, posterior buccal cavity widening posteriorly, with three pairs of rhabdions fused posteriorly and widening anteriorly, males with two testes pointing anteriorly and with reflexed posterior testis, and no pre-cloacal supplements. Gammanema agglutinans sp. nov. is characterised by a short, stout body often covered in adhering mucus and detritus, cuticle with minute spines, leaf-shaped somatic setae with ducts, sexual dimorphism in the shape of the amphideal fovea (loop-shaped in males and spiral in females), posterior buccal cavity with three pairs of broad, column-shaped rhabdions fused anteriorly, intestine cells with orange-brown granules, and small tubular pre-cloacal supplements. Bendiella gen. nov. is most similar to Halichoanolaimus, but differs from the latter, and all other genera of the family Selachinematidae, in having a cuticle with lateral differentiation consisting of longitudinal rows of larger dots, and from all other genera of the Choniolaiminae in lacking pre-cloacal supplements. Bendiella thalassa gen. et sp. nov. is characterised by amphideal fovea with 5.25 turns, anterior buccal cavity with twelve rhabdions, each with a pair of pointed projections at posterior extremity, posterior buccal cavity with three Y-shaped pairs of slender rhabdions fused from two thirds of distance from anterior ends, and conico-cylindrical tail.

The munnopsidid genus Notopais Hodgson, 1910 is taken out of synonymy with Echinozone Sars, 1897. The type species Notopais spicata Hodgson, 1910 and Notopais quadrispinosa (Beddard, 1886) are redescribed and three new species described: Notopais beddardi n. sp. collected from Antarctica at a depth of less than 37 metres; Notopais minya n. sp. collected from the south-eastern Australian continental slope between the depths of 429 466 metres; and Notopais zealandica n. sp. collected from the Chatham Rise between the depths of 1386 1640 metres, off the south-eastern New Zealand coast. Notopais is distinguished from Echinozone by three defining characters: the flattened appearance of the ventral side of the cephalon, the presence of pedestal setae on the pereonites and antenna 2 article 1 with produced distolateral angle with prominent spine and distal robust seta. This genus is exclusively found in the Southern Hemisphere and is known from Antarctica and the south-western Pacific.

All anthroleucosomatids from the Caucasus, both new and previously described, are classified in eight endemic complexes, arranged as follows in alphabetic order: the Alloiopus complex, the Caucaseuma complex, the Dentatosoma complex, the Enghoffiella complex, the Flagellophorella complex, the Herculina complex, the Ratcheuma complex and the Vegrandosoma complex. The genus Metamastigophorophyllon Ceuca, 1976 (the type-species: Mastigophorophyllon giljarovi Lang, 1959, adequately redescribed from new material), is a new subjective senior synonym of Persedicus Mauriès, 1982, syn. nov., being also newly transferred from the family Mastigophorophyllidae to the family Anthroleucosomatidae, comb. nov. The following two new combinations are also proposed: Heterocaucaseuma mauriesi (Golovatch and Makarov, 2011), comb. nov. ex Anamastigona Silvestri, 1898; and Metamastigophorophyllon martensi (Mauriès, 1982), comb. nov. ex Persedicus Mauriès, 1982. An identification key to and distribution maps for all known species of Caucasian Anthroleucosomatidae are provided, as well as brief remarks on distributions and on cave-dwelling taxa.

Holothurians of the family Psychropotidae are widely distributed, but remain least studied deep-sea holothurians. On an expedition in the Western Pacific, six psychropotid specimens were collected by the Jiaolong human operated vehicle (HOV). Through morphological examination, four of them were identified as a new species, Benthodytes jiaolongi sp. nov., which was characterized as having minute papillae, narrow brims, and terminal anus; the ossicles were either rods or primary crosses. The remaining two specimens were identified as Psychropotes verrucicaudatus Xiao, Gong, Kou & Li, 2019, which was first recorded at the Kyushu-Palau Ridge. The phylogenetic analysis confirmed the classification status of B. jiaolongi and P. verrucicaudatus, and indicated a paraphyletic relationship within the genus Benthodytes. The new species clustered with Benthodytes sanguinolenta and was separated from the clade containing the other Benthodytes species.

A new endemic species of triplefin Ruanoho scurra is described from deep water (108–216 m) on the shelf region around coastal New Zealand (Northland to Stewart Island). It is differentiated from its congeners by the combination of fresh colour (bright yellow spots on the head and anterior body, oblique lines on the dorsal and anal fins, and sub-vertical lines on the caudal) as well as some proportional measurements. Comments are made on the relationship with its congeners, and evolutionary history of the family in New Zealand waters, along with observations on the habitat in which this new species is found. This paper formally describes the species first mentioned in Stewart & Clements 2015:1523 as the polkadot triplefin.

A review of species of the crangonid genus Metacrangon Zarenkov, 1965 (Decapoda: Caridea) from the Northwest andtropical Southwest Pacific Ocean is presented. Twenty-one species, including seven new to science, are recognized: M.asiaticus (Kobjakova, 1955) from the Kuril Islands and Komandor Islands; M. bythos n. sp. from Japan; M. clevai n. sp.from the Solomon Islands and Vanuatu; M. cornuta Komai & Komatsu, 2009 from Japan; M. holthuisi Komai, 2010 fromJapan; M. karubar n. sp. from Indonesia to Solomon Islands; M. laevis (Yokoya, 1933) from northern Japan and the Rus-sian Far East; M. longirostris (Yokoya, 1933) from Japan; M. miyakei Kim, 2005 from Japan; M. monodon (Birshtein &Vinogradov, 1951) from the North Kuril Islands; M. nipponensis (Yokoya, 1933) from Japan; M. obliqua n. sp. from Ja-pan; M. ochotensis (Kobjakova, 1955) from the South Kuril Islands; M. proxima Kim, 2005 from Japan; M. punctata n.sp. from Indonesia, Solomon Islands and New Caledonia; M. robusta (Kobjakova, 1935) from the Sea of Japan and theSea of Okhotsk; M. similis Komai, 1997 from Japan; M. sinensis Fujino & Miyake, 1970 from the northern part of the EastChina Sea; M. trigonorostris (Yokoya, 1933) from Japan; M. tropis n. sp. from Japan; and M. tsugaruensis n. sp. fromJapan. These species are classified into two informal species groups. The new species are fully described and illustrated.Some previously known species, for which detailed descriptions along modern standards are deemed necessary, are rede-scribed. Metacrangon asiaticus is elevated from a subspecies of M. variabilis to full species status. A key to aid in theidentification of the western Pacific species is provided. Bathymetrical and geographical distributions of the treated spe-cies are summarized. It is strongly suggested that each species is highly localized. The species richness is highest in waters around the Japanese Archipelago (17 of the 41 known species occur in the areas).

New fossils referable to the Cancridae Latreille, 1802 extend the known stratigraphic range of the family into the middle Eocene and the geographic range into South America. Each genus within the family has been reevaluated within the context of the new material. A suite of diagnostic characters for each cancrid genus makes it possible to assign both extant and fossil specimens to genera and the two cancrid subfamilies, the Cancrinae Latreille, 1802, and Lobocarcininae Beurlen, 1930, based solely upon dorsal carapace morphology. Cheliped morphology is useful in assigning genera to the family but is significantly less useful at the subfamily and generic level. Each of the four subgenera sensu Nations (1975), Cancer Linnaeus, 1758, Glebocarcinus Nations, 1975, Metacarcinus A. Milne Edwards, 1862, and Romaleon Gistl, 1848, are elevated to full generic status. Additionally, three new genera and three new species accommodate the new, as well as some previously described taxa, and include Anatolikos new genus, Anisospinos berglundi new genus and species, and Notocarcinus sulcatus new genus and species and several new combinations. Recognition of new genera and reassignment of several species within the Cancrinae indicates that that subfamily may have arisen in the southern hemisphere, contrary to the previous interpretation of the subfamily as a primarily North Pacific or Tethyan group. The Lobocarcininae was primarily a Tethyan group.
