Abstract Thirteen new genera and three new families of cheilostome Bryozoa are described from the New Zealand biogeographic region, centred on Zealandia, between 26.42° (northern Norfolk Ridge) and 54.02°S latitude (south-east Campbell Plateau) from coastal waters to bathyal depths (46‒1676 m). The new genera, comprising 15 new and one previously described Zealandian species, are: Elementella (Elementellidae n. fam.), Niwapora, Quasicallopora, Quitocallopora, Judyella (Calloporidae), Ellisantropora (Antroporidae), Rhizellisina (Ellisinidae), Radixenia (Calloporoidea incertae sedis), Granomurus (Granomuridae n. fam.), Carolanna (Bugulidae), Borioplebs (Borioplebidae n. fam.), Seabournea (Cribrilinidae) and Waeschenbachia (Romancheinidae). A new Recent species of the otherwise Eocene‒Miocene genus Vincularia is also described from deep water on the Three Kings Ridge. Two new combinations are created – Judyella precocialis (Gordon, 1984) and Ellisantropora aggregata (Gordon, 1984). Ellisantropora tilbrooki sp. nov. is also introduced for a species from Torres Strait. Four of the deep-sea genera (three from one station on the northern Norfolk Ridge, one from a station on the Three Kings Ridge) have species with plesiomorphies or distinctive skeletal characters that suggest they are relict. Almost half of the new species form spot-like colonies on hard substrata.

Fifteen new genera of cheilostome Bryozoa are described from the New Zealand biogeographical region, centred on Zealandia, between 29° and 59°S latitude from shallow coastal waters to abyssal depths. The new genera are:Cavelliella,Mangana,Recapitulator(Calloporidae),Microblestrum,Stolomicropora(Pyrisinellidae),Otomicropora,Rosemariella(Microporidae),Bioptica,Caesiopora(Romancheinidae),Cheilonellopsis(Lacernidae),Xenogma(Buffonellodidae),Bountyella(incertae sedis),Taylorius(Escharinidae),Fovoporella(Schizoporellidae) andRamicellepora(Celleporidae). Several new combinations are also recognized, i.e.Corbulella fossa,Fovoporella spectabilis,Kenaplousina canariensis,Taylorius incognitus,Taylorius masoni,Taylorius waiparaensisandXenogma rhomboidale. Ten of the new genera are nominally endemic to the New Zealand exclusive economic zone.RecapitulatorandMicroblestrum(on seamounts near the southern part of the Hjort Trench) andRosemariella(seamount in the Louisville Ridge) occur in extraterritorial waters,Xenogmaextends to Australia andTayloriusextends to South Africa.Tayloriusis also known from the Miocene andFovoporellafrom the Pliocene.RecapitulatorandManganahave plesiomorphies that are novel among Recent Calloporidae (respectively a costate ooecium and ‘pelmatoporine’ elongate adventitious interzooidal kenozooids) but which are found in some Cretaceous calloporids or cribrilinids.

Coleoptera Tenebrionidae

The tribe Heleini is redefined to exclude the genera Lepispilus Westwood, 1841, and Leaus Matthews & Lawrence, 1992, which become incertae sedis within the subfamily Tenebrioninae . Four generic names are synonymised as follows: Barytipha Pascoe, 1869, and Pezohelaeus Gebien, 1920, with Pterohelaeus Brême, 1842; Euhelaeus Gebien, 1920, with Emcephalus Kirby, 1828; and Saragella Carter, 1937, with Dysarchus Pascoe, 1866. The genus Saragus Erichson, 1842, is resurrected as separate from Celibe Boisduval, 1835, with which it had been confused, and two new genera (Boreosaragus and Cillibus) are proposed for other species formerly in Celibe, bringing the total to 14 genera in the tribe, which is distributed in Australia, New Zealand, New Guinea and Seram. A tentative phylogeny is proposed for the genera, the constituent species are either mentioned or reference is made to a former checklist, and the Australian distribution of all but two genera is plotted. Hypotheses are put forward on evolutionary trends and the past history of the tribe. The 27 new combinations proposed are listed in Appendices I and II at the end of the paper.

In this first part of the World catalogue of genus-group names in Elateridae, a nomenclatural review of the genera belonging to ten subfamilies is provided. All names are given with author name, year, and page of publication, type species, and type fixation. We list 132 valid genera in Agrypninae, 2 in Campyloxeninae, 4 in Hemiopinae, 11 in Lissominae, 2 in Oestodinae, 8 in Parablacinae, 2 in Physodactylinae, 2 in Pityobiinae, 1 in Subprotelaterinae, and 7 in Tetralobinae.

Abstract Deep-sea species are generally thought to be less tolerant of environmental variation than shallow-living species due to the relatively stable conditions in deep waters for most parameters (e.g. temperature, salinity, oxygen, and pH). To explore the potential for deep-sea hermit crabs (Pagurus tanneri) to acclimate to future ocean acidification, we compared their olfactory and metabolic performance under ambient (pH ∼7.6) and expected future (pH ∼7.1) conditions. After exposure to reduced pH waters, metabolic rates of hermit crabs increased transiently and olfactory behaviour was impaired, including antennular flicking and prey detection. Crabs exposed to low pH treatments exhibited higher individual variation for both the speed of antennular flicking and speed of prey detection, than observed in the control pH treatment, suggesting that phenotypic diversity could promote adaptation to future ocean acidification.
