“…For example, Bamber (2005) described 24 new species from Esperance Bay, Guţu (2006a) reported 13 new species from tropical zones of Australia, Edgar (2008) reported 12 new species of the family Tanaididae in Tasmanian waters, and Błażewicz-Paszkowycz & Bamber (2012) described 42 new species from the Bass Strait. As a result, the number of the tanaidaceans known to occur along the Australian coast increased from 22 to 209 (as summarized by Bamber, 2008 ; Edgar, 2008 ; Błażewicz-Paszkowycz & Bamber, 2009 ; Błażewicz-Paszkowycz & Zemko, 2009 ; Stępień & Błażewicz-Paszkowycz, 2009a , 2009b ; Błażewicz-Paszkowycz & Bamber, 2012 ; Edgar, 2012 ; Jóźwiak & Jakiel, 2012 ; Bamber, 2013 ; Bamber & Błażewicz-Paszkowycz, 2013 ; Stępień & Błażewicz-Paszkowycz, 2013 ; Gellert & Błażewicz, 2018 ). This demonstrates the high diversity of these small and poorly recognized peracarids along the Australian coast ( Bamber & Błażewicz-Paszkowycz, 2013 ), with a high level of endemism ( Błażewicz-Paszkowycz & Bamber, 2012 ; Błażewicz-Paszkowycz, Bamber & Anderson, 2012 ).…”

Based on material collected from the shelf off southeast Australia (offshore of Portland), a new genus and new species, Muvi schmallenbergi gen. nov., sp. nov., of the tanaidacean family Metapseudidae, is described. Muvi is distinguishable from other genera within the subfamily Chondropodinae by having equally long antennular flagella. It also differs from other Chondropodinae by a combination of characters such as eyelobes with a group of visual elements, rostrum with smooth lateral edges, pereonites with lateral processes and pleotelson lacking lateral process, antennule article-1 with a single apophysis, maxillule inner lobe well-developed, labial palp bearing three distal setae, cheliped exopod well-developed and setose, pereopod-1 coxa with distinct apophysis, pleopods in five pairs, and uropod basis without apophysis. The genus Deidamiapseudes Sganga & Roccatagliata, 2016 is moved from Chondropodinae (Metapseudidae) to Apseudoidea incertae sedis. An identification key for the genera within Chondropodinae is given, and their distribution is discussed.

“…four families (Apseudidae: one species; Agathotanaidae: two species, Anarthruridae six species, Paratanaidae: one species) are formally described (three species were described from SE Australia) (Larsen and Heard, 2001;Jóźwiak and Jakiel, 2012;Bamber and Błażewicz-Paszkowycz, 2013;Gellert and Błażewicz, 2018). For this reason tanaids are regarded as a comparatively non-diverse group, especially when compared to the other well studied taxa as Isopoda being represented in SE Australia by 51 families (Poore et al, 1994).…”

In the current paper, we present the description of five new species of pseudotanaids sampled off the Bass Strait during two campaigns (SLOPE), which took place in 1986/8 and 1994 from the upper continental margin (slope) at depths 200–1550 m, hopefully starting to fill a gap in the knowledge of this major habitat. From five species, two occurred off eastern coast between Gippsland and Jervis Point and three others on the southern coast between Great Otway (Otway Point) and Kangaroo Island. These five species bring the total number of described pseudotanaid species 94 and to six in Australian waters.

“…Genus Agathotanais was established to allocate Agathotanais ingolfi Hansen, 1913, discovered off Iceland during the Danish Ingolf Expedition (Hansen, 1913). It was described and marked as the most aberrant among all tanaids due to its rudimentary antenna, cheliped attached directly to the cephalothorax, the appearance of the pleopods in juvenile males (Hansen, 1913), and the setulose surface of its body (Larsen, 2005;Jóźwiak and Jakiel, 2012;Kakui and Kohtsuka, 2015). Hansen (1913) placed Agathotanais within the family Tanaidae Dana (1849), the only existing tanaidacean family at that time, but few decades later the Agathotanais, together with Paragathotanais, was transferred to the newly erected family Agathotanaidae Lang, 1971.…”

Agathotanais is one of the seven genera classified into the family Agathotanaidae. So far, 12 species have been described for the genus, seven of which are known from the Pacific. However, considering the present poor state of knowledge on deep-sea environments, a much higher number of Agathotanais species than currently known can be suspected. Among the studied material, collected from below 1,000 m during five deep-sea expeditions in different parts of the Pacific Ocean, we identified eight species: two of them were already known to the science and five species were identified as new to knowledge and their formal description is presented in the paper: two from the North West Pacific (the Sea of Okhotsk and Kuril-Kamchatka Trench), two from the Central Pacific (Clarion-Clipperton Fracture Zone), and one from the Australian slope. The eighth Agathotanais species in our material was determined using a molecular approach, but it was represented by only one partially destroyed individual and could therefore not be formally described. The proportion of Agathotanais collected at the Sea of Okhotsk was the highest (22%), whereas the numbers were substantially lower for the Kuril-Kamchatka Trench, and the Central and the Southern Pacific. Molecular analyses confirmed the monophyly of Agathotanais and Paragathotanais and a close relationship between both genera. Moreover, a close relationship between the two Australian species was revealed. As a result of our findings, the number of species known from the Pacific increased from 5 to 11, with the total number of species in this genus increasing from 12 to 17. An updated identification key for Agathotanais species is given.
