Two new species of the genus Austroniscus Vanhoeffen, 1914 (Isopoda: Asellota: Nannoniscidae) from the Antarctic shelf

During the BENDEX expedition (BENthic Disturbance-EXperiment) with RV Polarstern in Antarctic summer 2003/04, species of the genus Austroniscus Vanhoeffen, 1914 were sampled from the continental shelf of the eastern Weddell Sea. Besides Austroniscus ovalis Vanhoeffen, 1914, which is the first record of this species from western Antarctica, two other species were found, i.e. Austroniscus chelus sp. nov. and Austroniscus obscurus sp. nov. They both bear many resemblances to Austroniscus ovalis, but can be easily distinguished from A. ovalis by the shape of the rostral crest and the first pereonite. The two new species are very similar to each other but differ in the number of articles of the antennula and the shape of pleopods 3 to 5.

Collections made during the REVIZEE program along the continental shelf, oceanic banks of the Archipelago of Fernando de Noronha and the North Chain Banks of Brazil, revealed a number of tanaidaceans species belonging to the genus Apseudes (Apseudidae). Two new species, Apseudes noronhensis and A. aisoe, are described here as is the first record of the genus Apseudes in Brazilian waters. Several diagnostic characters attributed to Muramurina were found during this study to be inconsistent and Muramurina is here suggested as being a junior synonym of Apseudes.

The munnopsid isopod genus Bathybadistes Hessler & Thistle has undergone several rearrangements since its initial inception. This genus was originally established for Bathybadistes hoplitis Hessler & Thistle and included eight species transferred from Ilyarachna Sars. Kussakin (2003) transferred four species to Echinozone Sars and one species back to Ilyarachna; he did not examine the other Bathybadistes species. The discovery of two new species of Bathybadistes has provided additional information on this genus. Using new and existing data, the present study used phylogenetic methods to test the validity and composition of Bathybadistes. Two outgroup and 15 ingroup taxa were analysed, including all nine species originally designated as Bathybadistes. The result of this analysis supports the validity of Bathybadistes. Echinozone appears to be paraphyletic because the four species moved to this genus by Kussakin (2003) do not align themselves with its type species, Echinozone coronata (Sars). Bathybadistes is rediagnosed and two new species, the first from the southern hemisphere, are described: Bathybadistes andrewsi, sp. nov. from ~3300-m depth off the west coast of New Zealand; and Bathybadistes fragilis, sp. nov. from ~4750-m depth in the eastern Weddell Sea, Antarctica.

Additionally the first record of a male of Arthrura monacantha (Vanhöffen, 1914) is presented. The possibility of the development of eggs and mancas outside the marsupium is considered.

AbstractTwo new ancorabolid species, Ceratonotus magellanicus sp. n. and Ceratonotus antarcticus sp. n., are described from the Straits of Magellan (Chile) and from Halley Bay (Weddell Sea, Antarctica), respectively. This is the first record of the genus from the Southern Hemisphere extending its range to the extreme south of the globe. Both new species are clearly distinct, each characterized by several unique features. They share a few characters which are absent in the two known species from the Northern Hemisphere. It is, however, not clear yet whether this indicates that they represent a subgroup distinct from the northern species within the genus.

A New Species

Based on benthic material collected during the BIOPEARL (Biodiversity, Phylogeny, Evolution and Adaptive Radiation of Life in Antarctica) II expedition on board RRS “James Clark Ross” a new nannoniscid species,Regabellator brixorumsp. n., is described from the Pine Island Bay continental shelf, western Amundsen Sea (Antarctica). The new species most closely resemblesRegabellator armatus(Hansen, 1916) but can be distinguished from this species by possessing ventral spines on pereonites 1-4, the shape of the cephalothorax anterior margin and the length of the pereonite 7 ventral spine. The genusRegabellatorhas been previously recorded from the North and South-eastern Atlantic and here exclusively from the deep sea (1946 m and below). The new species represents the first record of the genusRegabellatorfrom the Antarctic continental shelf and thus greatly extends hitherto known latitudinal and bathymetric ranges for this genus.

In May–June 2017 an expedition on board RV ‘Investigator’ sampled benthic communities along the lower slope and abyss of eastern Australia from off Tasmania to the Coral Sea. Over 200 sabellariid specimens of the genera Phalacrostemma and Gesaia were collected during the voyage and deposited in the Australian Museum. Here we describe two new species Gesaia csiro n. sp. (4414–4436 m) and Phalacrostemma timoharai n. sp. (1013–1093 m). We did not formally describe another species of Phalacrostemma due to poor condition of the single specimen. Gesaia csiro n. sp. is the first record of the genus from Australian waters (only a planktonic larva attributed to the genus has previously been recorded), and it can be distinguished from other congeners by the smooth surface of inner paleae, distal thecae of outer paleae with long, irregular and expanded distal fringe and circled distal margin. Phalacrostemma timoharai n. sp. differs from congeners by the following combination of characters: presence of the buccal flap, absence of tentacular filament, 18–22 pairs of outer paleae, two pairs of neuropodial cirri on first thoracic segment, and only one pair of lateral lobes on second thoracic segment. Morphological descriptions are accompanied by mitochondrial cytochrome c oxidase subunit 1 (COI) and ribosomal (16S, 18S and 28S) sequence data. A key to all Australian species of sabellariids is given.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.
