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.

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.

Bougainvillia aberrans n.sp. is described from Bermuda in the western North Atlantic Ocean. Specimens were collected at a depth of 150 fathoms (274 m) from the polypropylene buoy line of a crab trap. The hydroid colony of B. aberrans is erect, with a polysiphonic hydrocaulus, a smooth to somewhat wrinkled perisarc, hydranths having a maximum of about 16 tentacles, and medusa buds arising only from hydranth pedicels. Medusae liberated in the laboratory from these hydroids differ from all other known species of the genus in having a long, spindle-shaped manubrium, lacking oral tentacles, having marginal tentacles reduced to mere stubs, and being very short-lived (surviving for a few hours at most). Gonads develop in medusa buds while they are still attached to the hydroids, and gametes are shed either prior to liberation of the medusae or shortly thereafter. The eggs are surrounded by an envelope bearing nematocysts (heterotrichous microbasic euryteles). The cnidome of both hydroid and medusa stages consists of desmonemes and heterotrichous microbasic euryteles. The diagnosis of the genus Bougainvillia is modified to accommodate this new deep-water species.

AbstractAhnea keejeongi Park and Carlton (Coleoptera: Staphylinidae: Pselaphinae), a new genus and new species of New Zealand endemic beetle belonging to the supertribe Faronitae is described. Six previously described species are included to this genus and four species are synonymised as follow: Sagola dissonans Broun, 1921 and S. planicula Broun, 1921 under Ahnea ventralis (Broun, 1912); S. carinata Broun, 1912 and S. lineiceps Broun, 1921 under Ahnea lineata (Broun, 1893). A key to species, habitus photographs, line drawings of diagnostic characters, and distribution maps are provided.

The male and female of Neotanais krappschickelae n.sp., from the Subantarctic off the Falkland Islands are described from the RV Eltanin deep-water cruises of 1962. Both male and female of the new species can be separated from other species by the combination of characters including: a densely setose dorsal margin of the cheliped carpus, dactylus and fixed finger of subequal length; cheliped sclerite, all pereopodal bases, and posterior-lateral edges of pereonites with numerous plumose setae. The recent activity within tanaidacean taxonomy including neotanaid taxonomy has made it necessary to re-diagnose Neotanais.
