Habitat. This species has been reported on bottoms of shell debris (García Raso 1996), mud, mud with amphipod tubes, bioturbated mud, mud with cold-water coral debris (mainly Lophelia pertusa and Madrepora oculata ) (d’Udekem d’Acoz 1999; Sakai et al. 2015), at depths of 13 to 1432 m (Dworschak 2000). Our specimens were all captured in muddy coral rubble, at depths between 322 and 522 m. Distribution. East Atlantic from Iceland and Norway southwards to South Africa, including Mediterranean Sea (Ngoc-Ho 2003; Sakai 2011). Previously reported from Mauritanian waters by Sakai & de Saint Laurent (1989) and Sakai et al. (2015). Remarks. This species has been reported off Mauritania at 587 to 600 m (Sakai & de Saint Laurent 1989) and between 483 and 545 m (Sakai et al. 2015), which concurs with our findings. Along the West African coast, this species has also been reported slightly deeper at 719–724 -m depth off Morocco (García Raso 1996), at 300 and 380 -m depth off Namibia (Macpherson 1983 as Calocaris barnardi ) and shallower at 84 and 162 -m depth off the South African Atlantic coast (Barnard 1950 as Calocaris ( Calocaris ) barnardi ). : Published as part of De Matos-Pita, Susana S. & Ramil, Fran, 2015, Additions to thalassinidean fauna (Crustacea: Decapoda) off Mauritania (NW Africa) with the description of a new genus and a new species, pp. 571-587 in Zootaxa 4020 (3) on pages 575-576, DOI: 10.11646/zootaxa.4020.3.9, http://zenodo.org/record/238547 : {"references": ["Ngoc-Ho, N.
