The identity of the pilumnid crab, Pilumnus dofleini Balss, 1933, is reassessed based on the female holotype and additional male specimens from Sagami Bay and the Sea of Japan, Japan. Three new species allied to P. dofleini are described and illustrated: P. curvipenis n. sp. from the Izu Islands, Japan; and P. armatus n. sp. and P. bohol n. sp. from the Bohol Sea, the Philippines. These four species are diagnosed, compared and differentiated from the related P. acanthosoma Ng, 2000.

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.

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).

A New Species

A new species of congrid eel, Bathycongrus villosus sp. nov., is described from the Philippines and Vanuatu. It is similar to some of the small-toothed species currently placed in Bathycongrus and to the species of Bassanago. In this paper we compare the new species to Bassanago albescens (Barnard, 1923) and to Bathycongrus parviporus Karmovskaya, 2011, which it most closely resembles. An analysis of 19 characters shows that it agrees with Bat. parviporus in 16 characters and with Bas. albescens in one. In two characters, the three species are all different. We therefore place it in Bathycongrus.

Morphological And Molecular Characterization

Members of genus Iridogorgia Verrill, 1883 are the typical deep-sea megabenthos with only seven species reported. Based on an integrated morphological-molecular approach, eight sampled specimens of Iridogorgia from seamounts in the tropical Western Pacific are identified as three new species, and two known species I. magnispiralis Watling, 2007 and I. densispicula Xu, Zhan, Li and Xu, 2020. Iridogorgia flexilis sp. nov. is unique in having a very broad polyp body base with stout and thick scales. Iridogorgia densispiralis sp. nov. can be distinguished by rods present in both polyps and coenenchyme, and I. verrucosa sp. nov. is characterized by having numerous verrucae in coenenchyme and irregular spindles and scales in the polyp body wall. Phylogenetic analysis based on the nuclear 28S rDNA indicated that I. densispiralis sp. nov. showed close relationships with I. splendens Watling, 2007 and I. verrucosa sp. nov., and I. flexilis sp. nov. formed a sister clade with I. magnispiralis. In addition, due to Rhodaniridogorgia fragilis Watling, 2007 nested into the Iridogorgia clade in mtMutS-COI trees and shared highly similar morphology to the latter, we propose to eliminate the genus Rhodaniridogorgia by establishing a new combination Iridogorgia fragilis (Watling, 2007) comb. nov. and resurrecting I. superba Nutting, 1908.

Examination of Dardanus sanguinocarpus Degener, 1925 (type locality Hawaii), and specimens closely allied to D. sanguinocarpus collected from several localities in the western Pacific revealed the existence of three hitherto unknown species superficially resembling D. sanguinocarpus. These three species are described here as D. robustus, sp. nov., D. longior, sp. nov., and D. umbella, sp. nov., and Dardanus sanguinocarpus is redescribed.

The identity of the tree-spider crab, Parasesarma leptosoma (Hilgendorf, 1869) (family Sesarmidae), which is believed to be widely distributed in the Indo-West Pacific, is reassessed and shown to be a species-complex with nine species, seven of which are here described as new. Parasesarma leptosoma sensu stricto is now restricted to South and East Africa; and P. limbense (Rathbun, 1914) from Sulawesi, which had been regarded as a junior synonym, is here recognized as a valid species. The following species are described as new: P. gecko n. sp. from Vanuatu, Fiji, Guam and Japan; P. macaco n. sp. from Taiwan and the Philippines; P. kui n. sp. from Taiwan; P. parvulum n. sp. from the Philippines; P. gracilipes n. sp. from Indonesian Papua; P. purpureum n. sp. from Malaysia; and P. tarantula n. sp. from Sulawesi, Indonesia. The nine species of the Parasesarma leptosoma species-complex can be separated by the different shapes of their carapaces, the form of the dactylar tubercles on the male chelipeds, proportions of their ambulatory legs and the structure of the male first gonopod.
