Two species of Serolidae, Caecoserolis carinata sp. nov. and Caecoserolis bicolor sp. nov. are described from northern New Zealand waters, the first record of the genus from New Zealand. A third species, a juvenile is recorded as Caecoserolis sp. All are deep-water species. C. carinata can be identified by the median row of prominent tubercles, and was collected from the southern New Caledonia Trough, Tasman Sea at depths of 2930–3184 m; C. bicolor has paired nodules on the head linked by a V-shaped ridge, a broad body, widest at pereonites 3 and 4, and occurs off Hawkes Bay, off eastern North Island, at depths of 2119–2337 m.

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.

Among the Brachyura from the Kermadec Islands in the invertebrate collection of the National Institute of Water and Atmospheric Research, Wellington, New Zealand (NIWA), are two specimens representing two deep-water species previously not known from the region. Both specimens were collected at the same station, together with the paratypes of the parthenopid crab, Garthambrus tani Ahyong, 2008. The new records are reported below to formally document their occurrence at the Kermadec Islands, New Zealand; both also represent the first records of their respective genera from New Zealand waters.  Measurements of specimens, in millimetres, refer to carapace length (cl) and carapace width (cw).

Natatolana rekohu sp. nov. from the Chatham Rise, off southeastern New Zealand is described and figured. Natatolana rekohu was collected at a depth of 2799 metres, close to the greatest recorded depth for this genus. The species is a scavenger, and was feeding on dead fish in a sediment trap. Natatolana rekohu is characterised by: reduced eyes; strongly indented anterior margin of the head; pentagonal frontal lamina, with weakly convex lateral margins; pleonites 1 and 2 not produced, 3 weakly and pleonite 4 rounded; pereopods 1 and 2 usually with 5 or 6 setae on the propodal palm. In males the large flat and widely separated penes and the strongly curved, wide and terminally toothed appendix masculina are additional diagnostic characters. As in most Natatolana the numbers of robust setae on the margins of the uropodal rami and pleotelson are also important in making a correct identification.

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.

This paper gave evidence of the occurrence of Thamnaconus modestoides in Indonesian waters. A specimen (271.15 mm SL) was collected from the Winenet fish market at Bitung, North Sulawesi in March 2008. It was reported being caught in the depth of 20-30 m, in association with other coral-reef fishes, despite the fact that member of Thamnaconus has been known as deep water species. The morphological features of this new record species were discussed and illustrated.

Abstract The Infraorder Astacidea comprises four superfamilies of decapod crustaceans: the freshwater Astacoidea and Parastacoidea and the marine Enoplometopoidea and Nephropoidea. The gill morphology of four species of crayfishes belonging to Astacoidea and Parastacoidea, two coral reef species of Enoplometopoidea, and 2 deep-water species of Nephropoidea are described and illustrated for comparisons and to determine characters characteristic to members of the family Parastacidae (Parastacoidea) from New Guinea. Morphology of the arthrobranchs and pleurobranchs were similar among all species, having a single stem with filament, but podobranchs of the parastacoideans differed from those of Astacoidea, being corrugated and tubular and having filaments. The astacoidean P. virginalis had a plate-like lamella with filament. The two nephropoid and two enoplometopoid species were similar to each other; their podobranch had a flat blade-like lamella without a filament and a shaft with a filament. The gill formulae of the New Guinea species of Cherax were the same as those of the Australian congeners, but the formula of the New Zealand Paranephrops planifronsWhite, 1842 was the same as those of the South American parastacids.
