A New Species

Abstract A new species of Stegocephalidae, Parandania unicoxae sp. nov., is reported from hydrothermal vents in the Okinawa Trough. It is the fourth species described in the genus Parandania Stebbing, 1899. The new species is most similar to P. boecki (Stebbing, 1888), but it can be readily distinguished from P. boecki by the unilobate coxae 6-7.

A New Species

Abstract A new species of Eusiridae, Eusirus liui sp. nov. is described from a hydrothermal vent on Okinawa Trough, North-West Pacific. The new species differs from the other 30 congeneric species mainly by the following combination of characters: the acute rostrum reaching to 1/3 the length of peduncular article 1 of antenna 1; the absence of eyes; pleonite 3 without acute protrusion on dorsal margin, and the posterior margin of epimeron 3 with 18 serrations. A key to all known Eusirus species is provided herein. This is the fourth species within the Eusiridae that has been found from vent fields.

Three New Species

Five species of the hippolytid shrimp genus Lebbeus White, 1847 are reported from various deep-water hydrothermal ventsites in the Pacific Ocean: L. laurentae Wicksten, 2010 from the East Pacific Rise 13°N; L. wera Ahyong, 2009 from theBrothers Seamount, Kermadec Ridge, New Zealand; L. pacmanus sp. nov. from the Manus Basin, Bismarck Sea; L.shinkaiae sp. nov. from the Okinawa Trough, Japan; and L. thermophilus sp. nov. from the Manus and Lau basins, south-western Pacific. Lebbeus laurentae is fully redescribed because the original and subsequent descriptions are not totallydetailed. Differentiating characters among the three new species and close allies are discussed. Previous records of Lebbeus species from hydrothermal vents are reviewed.

A New Species

A new species of the neoverrucid barnacle genusNeoverrucaNewman, 1989,N. intermediasp. nov., collected from a hydrothermal vent area in the Okinawa Trough, is described and illustrated. It differs fromN. brachylepadoformisNewman, 1989 by the apical end of the inner surface of the movable scutum being in a pocket-form, with a longitudinal groove upwards, and without median ridges; the adductor ridge (or myophore) of the fixed scutum stout and the inner distal part of the scutum without longitudinal ridge.

A New Species

The molluscan diversity of deep-sea chemosynthetic ecosystems in Japan has been in general well documented with about 80 described species, of which over half are gastropods (Sasaki et al. 2005; Fujikura et al. 2012; Sasaki et al. 2016). Recently, however, a number of novel hydrothermal vent sites were discovered in the area using multibeam echo-sounding (Nakamura et al. 2015), providing opportunities for new discoveries. As a part of ongoing studies documenting the biodiversity of such sites, we present the first record of Columbellidae from hydrothermal vents, with a new species recovered from Natsu and Aki sites, in the Iheya North hydrothermal field (for map and background on the vent field see Nakamura et al. 2015).

A New Species

A new species of scale-worm, Lepidonotopodium okinawae sp. nov. from the Okinawa Trough is described. The new species differs from the other species of Lepidonotopodium by having 24 segments and numerous foveolae on the surface of elytra with one globular micropapilla in every foveola. A new record of the mussel commensal Branchipolynoe pettiboneae Miura & Hashimoto, 1991 is reported and described from the northern South China Sea, where for the first time the scale-worm is noted as occurring at a cold-seep. Keys to distinguish the species of Branchipolynoe and Lepidonotopodium are provided.

The Family

Seba longimerasp. nov., of the family Sebidae Walker, 1908, is described from hydrothermal vents in Okinawa Trough. Other two congenic species, S. bathybia Larsen, 2007 and S. profundus Shaw, 1989, are also reported from these hydrothermal vents, but the new species can be readily distinguished from them in having the merus of pereopods 5 and 6 extending beyond distal margin of carpus, coxa 4 smaller than coxae 2 and 3, and coxa 5 with the posterior lobe larger than the anterior one, rather than equilobate.

A New Species

One new species of alvinocaridid Alvinocaris kexueae sp. nov. is described from hydrothermal vents on the Manus Basin, Southwest Pacific. This is the fifteenth species in Alvinocaris Williams & Chace, 1982. The new species is easily recognized by the combination of the rostrum distinctively overreaching the distal end of the antennular peduncle, and the armature of its dorsal and ventral margins; the unarmed third abdominal segment, and by the posterior margin of the telson having one triangular tooth medially and 6 pairs unequal spines. It is morphologically most similar to A. brevitelsonis Kikuchi & Hashimoto, 2000 described from Minami-Ensei Knoll, Okinawa Trough, but can easily be distinguished from it by the proportionally longer rostrum, by the dorsal teeth of the rostrum, by the shape of the chela of the first pereiopod, and by the teeth on the fourth abdominal segment. The genetic divergence of COI gene analyzed clearly supports the new taxon.
