The samples were collected in two different moments, the first in the Potiguar Basin, northeast of Brazil (03/05 degrees S; 38/35 degrees W), covering the states of Rio Grande do Norte (RN) and Ceare (CE) in the year of 2011, and afterward on Rocas Atoll, located in the state of Rio Grande do Norte (RN) (3 degrees 51' S, 033 degrees 49' W; 3 degrees 52' S, 033 degrees 47' W) in the year of 2015. The occurrence of A. acanthitelsonis on Rocas Atoll and A. armata found along the continental slope in the Potiguar Basin, comprising both species, which were recorded for the first time in the southwestern Atlantic. This paper increases the number of Acanthephyra species recorded in Brazilian waters up to six and adds to our knowledge and distribution of deepsea fauna in the south Atlantic. specialized New Records Potiguar Basin Rocas Atoll northeastern Brazil Acanthephyridae ATLANTIQUE SUD BRESIL BRESIL NORDESTE 034 4184 1 193-200 2016 1175-5326 https://www.documentation.ird.fr/hor/fdi:010068300 10.11646/zootaxa.4184.1.13 1175-5326 [F B010068300] https://www.documentation.ird.fr/hor/fdi:010068300 https://www.documentation.ird.fr/intranet/publi/2016/11/010068300.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-12-06 2017-08-23 fdi:010068300 fre
