@article{Hendrycks_De Broyer_2022, title={New deep-sea Atlantic and Antarctic species of Abyssorchomene De Broyer, 1984 (Amphipoda, Lysianassoidea, Uristidae) with a redescription of A. abyssorum (Stebbing, 1888)}, volume={825}, url={https://europeanjournaloftaxonomy.eu/index.php/ejt/article/view/1829}, DOI={10.5852/ejt.2022.825.1829}, abstractNote={<p>During the Census of Marine Life <em>Polarstern</em> ANDEEP I-III and <em>Meteor </em>M79/1 DIVA-3 expeditions, autonomous baited trap systems were employed to sample the mobile, necrophagous amphipods from abyssal depths. Within DIVA-3 (July 10–August 26 2009), a free-fall baited trap was used successfully at three stations in the southwest Atlantic, once in the Argentine Basin and twice in the Brazilian Basin. A total of twenty-one stations were sampled by baited traps during the ANDEEP I-III (2002, 2005) cruises in the Southern Ocean. Trap sets recovered large numbers of scavenging lysianassoid and alicelloid amphipods, including specimens of the widespread and commonly considered cosmopolitan uristid species <em>Abyssorchomene</em> <em>abyssorum</em> (Stebbing, 1888). During examinations of these and other North Atlantic collections of <em>A. abyssorum</em>, two similar new species <em>A. patriciae</em> sp. nov. and <em>A. shannonae</em> sp. nov. were discovered. Important morphological characters which differentiate the two new species from their congeners are found in the shape of the head lobe, coxa 1, gnathopod 2, coxa 5, pereopod 7 basis and uropod 3 rami length. The new species are fully figured and an identification key is provided. <em>Abyssorchomene abyssorum</em> is redescribed and for the first time, the female is fully described and illustrated from new material. The Southern Ocean endemic <em>A. scotianensis</em> (Andres, 1983) is also described and illustrated from new collections to complement the original description.</p>}, number={1}, journal={European Journal of Taxonomy}, author={Hendrycks, Ed A. and De Broyer, Claude}, year={2022}, month={Jun.}, pages={1-76} }
