Three New Species

Most specimens of carnivorous sponges (Demospongiae, Poecilosclerida, Cladorhizidae) collected in the deep Pacific are usually found to be undescribed taxa. New Zealand’s EEZ, containing Kermadec Trench and Volcanic Arc to the north, Chatham Rise to the southeast, and parts of Macquarie Ridge to the southwest of New Zealand, as well as parts of Australia’s EEZ surrounding Macquarie Island, on Macquarie Ridge, have produced high numbers of new species and possibly new genera, and these are presently being described. In this work, we describe three new species of Cladorhizidae, each remarkable for the ‘exceptions to the rule’ that they represent. Abyssocladia carcharias sp. nov., from Monowai Seamount on the Kermadec Volcanic Arc, has the shape of a pedunculate disc with radiating filaments, and is characterized by three types of unique multidentate isochelae. Asbestopluma (Asbestopluma) anisoplacochela sp. nov., from the southern most end of the Three Kings Ridge, is erect and cylindrical with lateral expansions. In addition to the usual Asbestopluma microscleres, this species displays a new form of microsclere, termed ‘anisoplacochelae’. These unprecedented microscleres bear a plate-like central tooth similar to that of the placochelae of Guitarridae, but the ends are dissimilar in shape and dimensions. Asbestopluma (Asbestopluma) desmophora sp. nov., from Cavalli Seamounts off the north east coast of New Zealand, Hikurangi Plateau to the east of the North Island, and the Chatham Rise extending east from the South Island (all New Zealand EEZ), and on Macquarie Ridge (Australia EEZ), is an erect dichotomously branching sponge, that has desma megascleres densely packed into the enlarged base of attachment. Implications for the phylogeny of these three unusual species are considered.

Insular Populations

The forest-dwelling skinks of the Oligosoma oliveri (‘marbled skink’) species-complex, from the North Island of New Zealand, have proven difficult taxonomically because all mainland populations are extinct, obscuring patterns of distribution and population interaction. Twenty-four small insular populations have survived off the north-east coast of the North Island, which are at present classified into three species. In this paper I re-assess the available phenotypic, ecological, biogeographic and phylogenetic evidence associated with these skinks. As a result, O. pachysomaticum (Robb) is raised from synonymy with O. oliveri (McCann) and more precise historical distribution limits are inferred for each member of the group. Implications for the conservation management of each species are also discussed.

Sex Inversion

Gonads from snapper of age classes 0+ to 10+ years sampled from the north-east coast of New Zealand were examined histologically for evidence of sex inversion. All 0+ fish were undifferentiated, and all 1 + fish were immature females. 2+ to 4+ fish had gonads that were either ovary, ovo-testis or testis. Older fish were either male or female. Snapper reach sexual maturity at ages of 2-5 years, so the developmental pattern is one of juvenile sex inversion by some of the population, and functional gonochorism.

Rock Specimens

The new material on which this paper is based has lately been received through Mr. D. Ferguson, who recently investigated the geology of the island, and collected the rocks described in an earlier paper. It consists of twenty-seven rock specimens from the south-eastern end of the island, between Cape Disappointment and Cooper Island, and nine specimens from Gold Harbour on the north-east coast between Cooper Island and Royal Bay. All these were collected by the staff of the South Georgia Co., Ltd., under the instructions of Mr. Th. E. Salvesen, managing director, of Leith.

For researchers, isolated regions at the periphery of species’ distributions hold a peculiar fascination. The causes of their remoteness vary based on: distance (e.g. the Tropical Eastern Pacific), distance and countervailing currents (e.g. the Marquesas), location in a present day gyre (e.g. the Pitcairn Group) or the absence of present day means of veliger transport (e.g. the Vema Seamount). (Daughenbaugh & Beals 2013; Daughenbaugh 2015a & b, 2017). The northern New Zealand Region from the Kermadec Islands (Kermadecs) to the coastal and shelf areas in the northernmost part of New Zealand’s North Island (Northland), including the Poor Knights Islands (PKI), constitute the distributional boundaries for a number of Cypraeidae species. The boundaries are the result of the absence of coastal shelves along the east side of the Kermadec Ridge (Ridge) and precipitous drops to abyssal depths along Northland’s east coast continental shelf. Tropical waters, with their potential to transport Cypraeidae larvae, flow eastward from southern Queensland, Australia, entrained in the Tasman Front which terminates when reaching North Cape, the northernmost tip of Northland. There, the North Cape Eddy captures most of this flow while the remainder, the East Auckland Current (EAUC), flows intermittently southward along the eastern coastal, shelf and offshore areas of Northland into waters incapable of supporting Cypraeidae populations.
